Does the Manual IS300 ECU have only one part # from 2002-2005 or did they make a change in 04/05 possibly? thanks

Any 2002-2005 manual ECU should work and be plug n play. However the part numbers have changed throughout the years. I don't know if the software changed, I would think it did, but also the new numbers superseded the old ones.
These are all listed under a manual IS.
Car production year(s)--part number--ECU production dates
(2002) 89661-53310 (07/2001 - 01/2002)
(2002/3) 89661-53311 (02/2002 - 07/2002)
(2003/4) 89661-53490 (08/2002 - 07/2003)
(2004/5) 89661-53540 (08/2003-07/2004)
(2004/5) 89661-53450 (08/2004-)

Jason, is it possible that the different part numbers have nothing to do with internal changes and are different to meet some CARB mandate to have a specific ECU for each year, to match the Engine for that year?

^ haha, I have owned a sedan IS, I prefer the SX.

Mine is also going to be AR5 swapped, how long have you had yours swapped? whats the setup you are running, maybe you could write your thoughts on it in the AR5 swap progress thread.

P0500

I got this code after my swap.
I also got an abs code that shows C1203 with my TRAC light on.
I did a W55 swap on my 02 is300 and installed the MT ECU.
i wired from my cluster to the ECU aswell.
Any help would be great.
The P0500 comes on about 10 miles of driving ( 15 KM's roughly)

I believe P0500 is related to the speed sensor and the 2nd code has to do with the ABS like you said. I believe the manual is300 get their speed signal from the ABS so somehow these codes may be related. Does your speedometer work? I'm also waiting for someone else to help with your answer. You should list which wiring you did after the swap so the guys like Jason can help figure out where you may have gone wrong or if your ABS ECM may be bad or a bad wheel sensor. Sorry I couldn't be of more help as I haven't done the swap so I'm not 100% where you could have messed up a wire.

I've got a side question. Can that gear shift decal on the console for the manual IS300 be bought by itself or do you have to buy the whole console cover/plate or w/e its called?

I believe 02's get the speed off the transmission?

The automatics have 2 speed sensors, one for the input shaft and one for the tailshaft. The tailshaft sensor is how the ECU notes the speed, even for the 01's. The dash on the 01's is driving by the ABS but, the ECU is reading the transmission speed sensor.

I know this because the speed reported over OBD2 on my setup is different than the dash speed. My ECU is looking for a 3.26 diff, not the 3.73 I have.

So, my question is, did you hook up the transmission speed sensor when you did the swap? The manuals have one in the tailshaft.

My speedometer works, although I'm not sure how accurate it is.
I wired this way:

from A13(had to insert a pin) in the cluster to the connector B11 (had to insert a pin)

I did not hook up the speed sensor from the w55 transmission.
How do I do this?
I read that there is 3 wires coming out of it, where do they go?

So you converted to manual right? If you have the manual ECU and a manual W55 or so wouldn't the car no longer be looking for that sensor from the automatic? Does the manual ECU also look for a speed code in the manual transmission? If you get a diff from the same car you got the manual ECU for the swap it should be good then right?

I am swapping to manual, but I noticed the difference in reported speed from my V8 swap with automatic. I have an 01 so, it's possible things are different between it an the 02+ (besides the ABS). The speedometer will show, 60 for example but, the OBD2 stream shows 72. That tells me the ECU speed data is coming from the tailshaft sensor because the speed is off because of my diff ratio. At least with this ECU.

So, I'm theorizing that the ECU doesn't know how fast the car is going if you've only hooked up the ABS to the speedometer and not also hooked up the transmission speed sensor to the ECU.

Easy way to tell is hook up an OBD2 scanner and see what speed the ECU thinks the car is running compared to the speedometer speed.

The wiring harness for the automatic that you disconnect for the manual swap contains hookups for both speed sensors. It's the tailshaft sensor that measures speed.

BUT...After doing this and going on the test drive, it was still having a little bit of hesitation. Then I realized something....VERY loud exhaust noise coming from UNDER the car...this whole time there's been an exhaust leak between the down pipe and the exhaust pipe. The car was running like crap because the O2 readings were off and it was running crazy rich! aaaaaaaAAAAAAAAHHHHHH hahahahahaha

I never noticed it as I gave the car back to my mom right after doing the swap and obviously didn't hear the exhaust leak at that time. She didn't notice because she's simply used to driving old loud cars. Over the past year the leak has got loud enough for me to finally notice today on my extended test drive late at night with no other traffic around.

Wow.

Anyways, wiring is done. I know what the final issue is. Thank god.

True story

Thanks again for all your help Curran!!!! The Sportcross will finally be a little rocket!

I BELIEVE THAT I AM HAVING THE SAME INFORMATION,
where do these 3 wires tap into?

Wow, allot of reading there.

Did you have the C1203 code before the swap?

You do NOT have to wire the manual transmission speed sensor to car. the Combo meter already has its signal from abs.

Your Guages/ Combo meter get speed from the ABS. so it should be accurate as long as your tire size is appropriate.

Have you checked to see if your ECU is getting its speed signal?

I can guarantee that either the wiring is not done correctly or the pins you used are not the correct size. Atleast that is always the case when someone has problems. If this C1203 code your having is because a faulty abs ECU then I could see that also being the problem, but seeing your combo meter is getting speed atleast that part of it is working and if wired correctly your ecu will also get the speed signal.
