The TEC³ Engine Management System will run the following configurations:
4 Cylinder, 6 Cylinder, 8 Cylinder, 4 Cylinder (Dual Plug), Staged Injection, Sequential Injection
(From Lambchop)
Installation
In theory, the TEC3 only needs 2 sensors to get a motor up and running...the crank trigger and MAP sensor. The TEC3 uses a 60-2 trigger wheel, the wheel has 60 teeth with 2 of them missing, each tooth represents 6 degrees of advance allowing the TEC3 to have very accurate timing. A crank trigger sensor reads the wheel, the wheel needs to be installed in a specific orientation relative to piston 1 TDC, this tells the TEC3 engine speed and piston location/stroke. The MAP sensor is needed to tell the TEC3 engine load.
Pros: Very easy installation, accurate timing with high resolution.
Cons: Trigger wheel wobbles a little bit, cannot use stock crank wheel/sensor.
Tuning
The TEC3 has 2 main tables for tuning, VE and Ignition Timing. Once you install the TEC3, you can use the Tuning Wizard software to create a base map for you. You enter the injector size, MAP sensor size, horsepower level, and a few other injector parameters. From these inputs a raw fuel curve is created. You alter the VE table by either adding or removing up to 50% of fuel from it. Altering the Ignition Timing map is pretty straight forward, set the timing angle to ignite the air/fuel mixture.
Pros: Tuning software isn't too difficult to use, pretty straight forward.
Cons: The VE table allows a max of 50% of fuel modification. If you find yourself needing more than 50%, you'll need to alter the pulsewidth offset. If you change the pulsewidth offset, you'll need to go back and redo the rest of the VE table. Since the VE table is just a raw fuel curve, if you have an inconsistent MAP reading, you'll see your injector pulsewidth constantly change. This makes it a little difficult to get a very smooth idle. There's a way to work around this though and that's to use the TPS blend feature. The TPS blend feature allows you to use the TPS sensor voltage as a percentage of your MAP reading.
Inputs/Outputs
The TEC3 has 4 GPOs (general purpose outputs) and 4 GPIs (general purpose inputs). Two of the GPOs can be used as a PWM output. One of the GPIs can be used for auto-tuning another fuel map called the EGO table. There are some nice features of the GPIs like using a toggle switch that triggers a "Valet Mode" that will activate a RPM limit. Another feature is enabling a onboard data logger.
Fuel Enrichment/Cut off
The TEC3 has fuel enrichment for acceleration, intake air temperature correction, coolant temperature correction, battery voltage correction, deceleration fuel cut off, and over boost fuel cut off.
Knock Control
The TEC3 has a knock control feature that will retard timing and slowly add it back.
Pros: You can splice your stock knock sensor to it.
Cons: Reads only 1 knock sensor, the 2JZ has 2 knock sensors. There's no way to calibrate the knock sensor voltage.
Sensor Calibration
The TEC3 has a calibration option for TPS, knock, MAP, coolant, intake air temperature, and EGO.
Pros: Stock sensors can be used for most of the sensors.
Cons: The calibration is very limited, you can enter a min and max voltage value as well as a default error value.
Overall Opinion
Pros: The TEC3 has an unbelievable ignition system. It's very powerful and works well in the IS300s wasted spark setup. It's very easy to tune, easy to setup, is pretty complete (no need for an ignition amplifier or knock retard system), and works pretty well.
Cons: The tuning software is pretty buggy and the firmware has quite a few bugs. Granted all software in the world has their share of bugs but it comes down to how severe the bug is. Upgrading the firmware can cause the TEC3 to lock up, it's documented about 5% of the units will lock up...pretty scary statistic. Can't retrieve the cal file once it's downloaded on the unit.
E-Manage Blue
GReddy’s e-Manage is a cost effective programmable engine management system that allows you to properly tune your factory engine control without having to change the entire factory ECU system to an expensive "stand-alone" unit or the inconvenience of sending it out for a full ECU reprogram. The e-Manage system is a true universal "piggy-back" type unit that taps into most Japanese factory ECU wiring, by utilizing the vehicle’s existing sensors (or optional upgraded sensors if factory sensors are maxed out). The major benefit is the factory ECU settings become your "Base-MAP" for tuning. There is no need for extensive tuning for normal driving conditions, but does allow the tuner to fine tune, adjust for injector changes, and add new MAP(s) for situations the factory ECU is not capable of (like on-boost conditions). And as technological breakthroughs are achieved, we offer FREE updates via our greddy.com website’s Tech page. Basic functions will allow the tuner to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. An option for Honda VTEC cars will allow you to even adjust the VTEC shift point. Additional features are built into the system but are only accessible through the use of the e0-1, PRofec e-01 programmer or our PC-Windows based "e-Manage Support Tool" communication software (sold separately). There is a 16x16 airflow adjustment map, a maximum 50% larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 injector duty cycle map and the controls for adding up to 2 additional sub-injectors. If the "Optional Ignition Harness" and the software are used the unit has the ability to control a 16x16 ignition timing map. All of the above maps can also be map-traced in real-time as well. If the factory range of map or airflow meter is surpassed, you can incorporate a larger airflow meter or our "Optional GReddy Pressure Sensor and Pressure Harness" to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
(injector and ignition harnesses are separate from what i see here on their page, along with an array of other options. They dont come standard.)
E-Manage Ultimate
The GReddy e-manage Ultimate is as close to a stand-alone management system as you can get while maintaining the best features of a "piggy-back" engine management; an economical price, the usage of existing sensors, the ability to easily alter factory settings and not having to tune from scratch. But unlike the original e-manage, the Ultimate is more refined, requiring specific application usage (which we are constantly adding application updates that you can download FREE via greddy.com, Tech WebPages.) The benefit of this is, the included PC-based USB "Ultimate Support Tool" allows for even finer tuning capabilities, improved flexibility in fuel & ignition control and adds impressive data-logging qualities to make tuning quicker and easier. The increased number of input and output ports of the Ultimate, along with new built-in adapters add many new options to the unit. In addition to standard e-manage airflow-based adjustments, the Ultimate version includes new and upgraded features. The Parameter Set-up, tab menu format of the Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition. The ability to switch between 2 preset tuning Maps (i.e. Street or Race program) via externally mounted toggle switches. There are Maps for Individual cylinder adjustment for both Fuel and Ignition. There are also options to convert injection and ignition systems (i.e. group or sequential injection and group or individual fire ignition.) An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. There are also built-in Boost, Rev and Speed Limiter-Cut features. To create super smooth operation, there are various fine tuning Correction Maps to adjust for Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti Engine Stall, and Idle. To further aid in tuning, e-manage Ultimate’s improved integrated Monitoring, Map Tracing and Datalogging features far exceed any other piggyback controller on the market. Even when not connected to the software, 8 channels of datalogging (at 20msec intervals) can be recorded and stored to be reviewed later. With the Support Tool connected, over 30 channels can be covered. Other new features include: Improved RPM recognition, Warning Settings, Password Protection for individual tuning Maps, NVCS (Nissan), VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and numerous others in future updates. Ideal for optimizing and fine-tuning for performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers, the e-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
(same thing about harnesses from the blue apply here, along with an array of different sensors.)
Map ECU
The MAP-ECU replaces voltage and frequency based air flow meters with Manifold Absolute Pressure (MAP) based load sensing. Voltage types include the spring door flap and hot wire types used by numerous manufactures. Frequency based units are commonly known as Von Karmen Vortex Frequency air flow meter as used by Mitsubishi™ or DSM vehicles and some other manufacturers.
This MAP-ECU combines the functionality of other manufacturers Air Flow Converters and Vane to Pressure Converters into the one unit, plus more. It is supplied with a blank table for professional engine tuners who have the experience to customise the configuration. Pre-programmed units will follow for popular vehicles with starter tables, depending on demand. The MAP-ECU is programmed using a 2D Table Mode or the 3D Graph Mode. Both views allow real-time editing of the MAP-ECU configuration.
The MAP-ECU has a built in serial port which is connected to an Industry Standard PC running Microsoft(™) Windows2000(™) or WindowsXP(™).
Configuration and monitoring is accomplished using our proprietary graphical user interface. The graphical user interface allows real-time configuration and monitoring of the MAP-ECU, even while running the vehicle on a Dyno, etc.
The output data is computed from a 374 Zone table at over 100 times per second based on Manifold Absolute Pressure (-10 to +30 PSI) and RPM (0-8000).
Map ECU V2
The MAP-ECU2 replaces voltage and frequency based air flow meters with Manifold Absolute Pressure (MAP) based load sensing (Speed Density). Voltage types include the spring door flap and hot wire types used by numerous manufactures. Frequency based units are commonly known as Karman Vortex Frequency air flow meter as used by Mitsubishi™ or DSM vehicles and some other manufacturers.

Some other comments would be try to download the software for each of these engine management systems and play around with them a little to see if you like the feel of the set up. I found the user interfaces for some of these engine management systems rather clunky and non-intuitive. I felt that way about the AEM at first until I started using other emses. If you don't tune yourself, this is a don't care if you like to tinker, defiitely look into this.
Advantages of AEM:
1. Most things are user definable which is why you can use all stock sensors. a. If you have non-plug and play then you can wire into almost any car since cam/crank parameters can be set up to sync correctly.
b. You can tweak almost any parameter to get things running better.
2. Lot's of tuners around and forums with info.
3. Good bang for the buck
Disadvantages:
1. Because everything is configurable, setting it up for initial use for any car is a big task. Once the base map is done though, it's good to go
2. Questionable reliability. Some people have complained of poor reliability. I have not had this issue myself. My only complaint is that AEM cheaped out on some stuff such as high and low impedance injector drivers, and direct ignition coil drivers. Arguably this should make it more reliable since those things can produce more heat inside the box, but still!
3. Lack of ability to lock calibrations. Most EMSes can lock parts or all of calibrations, the AEM cannot easily be done especially by a regular end user. Some would argue why do you want to lock a cal anyway? Well, I would like to have the choice myself. The AEM was architected with this function but it was disabled.

The TEC³ Engine Management System will run the following configurations:
4 Cylinder, 6 Cylinder, 8 Cylinder, 4 Cylinder (Dual Plug), Staged Injection, Sequential Injection
(From Lambchop)
Installation
In theory, the TEC3 only needs 2 sensors to get a motor up and running...the crank trigger and MAP sensor. The TEC3 uses a 60-2 trigger wheel, the wheel has 60 teeth with 2 of them missing, each tooth represents 6 degrees of advance allowing the TEC3 to have very accurate timing. A crank trigger sensor reads the wheel, the wheel needs to be installed in a specific orientation relative to piston 1 TDC, this tells the TEC3 engine speed and piston location/stroke. The MAP sensor is needed to tell the TEC3 engine load.
Pros: Very easy installation, accurate timing with high resolution.
Cons: Trigger wheel wobbles a little bit, cannot use stock crank wheel/sensor.
Tuning
The TEC3 has 2 main tables for tuning, VE and Ignition Timing. Once you install the TEC3, you can use the Tuning Wizard software to create a base map for you. You enter the injector size, MAP sensor size, horsepower level, and a few other injector parameters. From these inputs a raw fuel curve is created. You alter the VE table by either adding or removing up to 50% of fuel from it. Altering the Ignition Timing map is pretty straight forward, set the timing angle to ignite the air/fuel mixture.
Pros: Tuning software isn't too difficult to use, pretty straight forward.
Cons: The VE table allows a max of 50% of fuel modification. If you find yourself needing more than 50%, you'll need to alter the pulsewidth offset. If you change the pulsewidth offset, you'll need to go back and redo the rest of the VE table. Since the VE table is just a raw fuel curve, if you have an inconsistent MAP reading, you'll see your injector pulsewidth constantly change. This makes it a little difficult to get a very smooth idle. There's a way to work around this though and that's to use the TPS blend feature. The TPS blend feature allows you to use the TPS sensor voltage as a percentage of your MAP reading.
Inputs/Outputs
The TEC3 has 4 GPOs (general purpose outputs) and 4 GPIs (general purpose inputs). Two of the GPOs can be used as a PWM output. One of the GPIs can be used for auto-tuning another fuel map called the EGO table. There are some nice features of the GPIs like using a toggle switch that triggers a "Valet Mode" that will activate a RPM limit. Another feature is enabling a onboard data logger.
Fuel Enrichment/Cut off
The TEC3 has fuel enrichment for acceleration, intake air temperature correction, coolant temperature correction, battery voltage correction, deceleration fuel cut off, and over boost fuel cut off.
Knock Control
The TEC3 has a knock control feature that will retard timing and slowly add it back.
Pros: You can splice your stock knock sensor to it.
Cons: Reads only 1 knock sensor, the 2JZ has 2 knock sensors. There's no way to calibrate the knock sensor voltage.
Sensor Calibration
The TEC3 has a calibration option for TPS, knock, MAP, coolant, intake air temperature, and EGO.
Pros: Stock sensors can be used for most of the sensors.
Cons: The calibration is very limited, you can enter a min and max voltage value as well as a default error value.
Overall Opinion
Pros: The TEC3 has an unbelievable ignition system. It's very powerful and works well in the IS300s wasted spark setup. It's very easy to tune, easy to setup, is pretty complete (no need for an ignition amplifier or knock retard system), and works pretty well.
Cons: The tuning software is pretty buggy and the firmware has quite a few bugs. Granted all software in the world has their share of bugs but it comes down to how severe the bug is. Upgrading the firmware can cause the TEC3 to lock up, it's documented about 5% of the units will lock up...pretty scary statistic. Can't retrieve the cal file once it's downloaded on the unit.
E-Manage Blue
GReddy’s e-Manage is a cost effective programmable engine management system that allows you to properly tune your factory engine control without having to change the entire factory ECU system to an expensive "stand-alone" unit or the inconvenience of sending it out for a full ECU reprogram. The e-Manage system is a true universal "piggy-back" type unit that taps into most Japanese factory ECU wiring, by utilizing the vehicle’s existing sensors (or optional upgraded sensors if factory sensors are maxed out). The major benefit is the factory ECU settings become your "Base-MAP" for tuning. There is no need for extensive tuning for normal driving conditions, but does allow the tuner to fine tune, adjust for injector changes, and add new MAP(s) for situations the factory ECU is not capable of (like on-boost conditions). And as technological breakthroughs are achieved, we offer FREE updates via our greddy.com website’s Tech page. Basic functions will allow the tuner to slightly alter factory injector duty-cycle (± 20% at 5 preset RPM points) by intercepting and altering airflow or MAP sensor signals. An option for Honda VTEC cars will allow you to even adjust the VTEC shift point. Additional features are built into the system but are only accessible through the use of the e0-1, PRofec e-01 programmer or our PC-Windows based "e-Manage Support Tool" communication software (sold separately). There is a 16x16 airflow adjustment map, a maximum 50% larger main injector correction adjustment, upgrade air flow meter adjustment, boost limiter cut, anti-engine stall, VTEC-fuel adjustment, real-time map trace, real-time display, real-time communication and basic Data-logging. With the use of our "Optional Injector Harness" and the software, the unit has the ability to control an additional 16x16 injector duty cycle map and the controls for adding up to 2 additional sub-injectors. If the "Optional Ignition Harness" and the software are used the unit has the ability to control a 16x16 ignition timing map. All of the above maps can also be map-traced in real-time as well. If the factory range of map or airflow meter is surpassed, you can incorporate a larger airflow meter or our "Optional GReddy Pressure Sensor and Pressure Harness" to set larger scales of adjustment. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
(injector and ignition harnesses are separate from what i see here on their page, along with an array of other options. They dont come standard.)
E-Manage Ultimate
The GReddy e-manage Ultimate is as close to a stand-alone management system as you can get while maintaining the best features of a "piggy-back" engine management; an economical price, the usage of existing sensors, the ability to easily alter factory settings and not having to tune from scratch. But unlike the original e-manage, the Ultimate is more refined, requiring specific application usage (which we are constantly adding application updates that you can download FREE via greddy.com, Tech WebPages.) The benefit of this is, the included PC-based USB "Ultimate Support Tool" allows for even finer tuning capabilities, improved flexibility in fuel & ignition control and adds impressive data-logging qualities to make tuning quicker and easier. The increased number of input and output ports of the Ultimate, along with new built-in adapters add many new options to the unit. In addition to standard e-manage airflow-based adjustments, the Ultimate version includes new and upgraded features. The Parameter Set-up, tab menu format of the Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition. The ability to switch between 2 preset tuning Maps (i.e. Street or Race program) via externally mounted toggle switches. There are Maps for Individual cylinder adjustment for both Fuel and Ignition. There are also options to convert injection and ignition systems (i.e. group or sequential injection and group or individual fire ignition.) An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. There are also built-in Boost, Rev and Speed Limiter-Cut features. To create super smooth operation, there are various fine tuning Correction Maps to adjust for Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti Engine Stall, and Idle. To further aid in tuning, e-manage Ultimate’s improved integrated Monitoring, Map Tracing and Datalogging features far exceed any other piggyback controller on the market. Even when not connected to the software, 8 channels of datalogging (at 20msec intervals) can be recorded and stored to be reviewed later. With the Support Tool connected, over 30 channels can be covered. Other new features include: Improved RPM recognition, Warning Settings, Password Protection for individual tuning Maps, NVCS (Nissan), VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and numerous others in future updates. Ideal for optimizing and fine-tuning for performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers, the e-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications.)
(same thing about harnesses from the blue apply here, along with an array of different sensors.)
Map ECU
The MAP-ECU replaces voltage and frequency based air flow meters with Manifold Absolute Pressure (MAP) based load sensing. Voltage types include the spring door flap and hot wire types used by numerous manufactures. Frequency based units are commonly known as Von Karmen Vortex Frequency air flow meter as used by Mitsubishi™ or DSM vehicles and some other manufacturers.
This MAP-ECU combines the functionality of other manufacturers Air Flow Converters and Vane to Pressure Converters into the one unit, plus more. It is supplied with a blank table for professional engine tuners who have the experience to customise the configuration. Pre-programmed units will follow for popular vehicles with starter tables, depending on demand. The MAP-ECU is programmed using a 2D Table Mode or the 3D Graph Mode. Both views allow real-time editing of the MAP-ECU configuration.
The MAP-ECU has a built in serial port which is connected to an Industry Standard PC running Microsoft(™) Windows2000(™) or WindowsXP(™).
Configuration and monitoring is accomplished using our proprietary graphical user interface. The graphical user interface allows real-time configuration and monitoring of the MAP-ECU, even while running the vehicle on a Dyno, etc.
The output data is computed from a 374 Zone table at over 100 times per second based on Manifold Absolute Pressure (-10 to +30 PSI) and RPM (0-8000).
Map ECU V2

Some other comments would be try to download the software for each of these engine management systems and play around with them a little to see if you like the feel of the set up. I found the user interfaces for some of these engine management systems rather clunky and non-intuitive. I felt that way about the AEM at first until I started using other emses. If you don't tune yourself, this is a don't care if you like to tinker, defiitely look into this.
Advantages of AEM:
1. Most things are user definable which is why you can use all stock sensors. a. If you have non-plug and play then you can wire into almost any car since cam/crank parameters can be set up to sync correctly.
b. You can tweak almost any parameter to get things running better.
2. Lot's of tuners around and forums with info.
3. Good bang for the buck
Disadvantages:
1. Because everything is configurable, setting it up for initial use for any car is a big task. Once the base map is done though, it's good to go
2. Questionable reliability. Some people have complained of poor reliability. I have not had this issue myself. My only complaint is that AEM cheaped out on some stuff such as high and low impedance injector drivers, and direct ignition coil drivers. Arguably this should make it more reliable since those things can produce more heat inside the box, but still!
3. Lack of ability to lock calibrations. Most EMSes can lock parts or all of calibrations, the AEM cannot easily be done especially by a regular end user. Some would argue why do you want to lock a cal anyway? Well, I would like to have the choice myself. The AEM was architected with this function but it was disabled.
