Depends on the IM you are running and IAC that goes with it. If the AEM can control it, you'll be OK.

I was just wondering for those that got the AEM Temp sensor, which one you got, 1/4" or 3/8" and where everyone installed it? Pic is worth a 1000 words

I currently just got the car put back together, 367whp and 333wtq on a mustang dyno. have TT internals now, w58 supra tranny, aem V2 from dezod, hks intercooler and bov, Precision 46 wastegate, comp TBB 6767 billet turbo. this is running at 14lbs boost, controlled with aem boost controller, also have aem wideband and running 91 octane fuel. Hoping to get temp sensor installed and fix temp as soon as i find out what size and where people are installing. Hoping to get meth injection and maybe up boost towards end of season this year.

Probably be quite difficult with a stock rad, but not impossible. I have no pics.

LOL Yea so not that easy fix, just like i was thinking. Anyone have schematic for changes to the AEM. I am electronics tech trained to IPC-610 Surface mount soldering. Would make it easier for me to just mod the AEM. I dont really feel like sending the aem away when i just got the car back together and tuned.

Not that simple. We can not provide a proprietary schematic and wiring info to you to do so on your own.

Should you want to take the matters into your own hands, you have voided your warranty with us and AEM.

Should you still chose to proceed, the simple modification would be remove the tap/splice into the factory coolant temp signal coming out of AEM C26. This signal would go directly to your chosen external ECT sensor. Let the factory remain untouched and the AEM will have it's own independent signal to read.

I just added a T fitting in the coolant line to the throttle body to install the AEM coolant sensor.
If you want a cleaner install, you can always use the second port next to the factory coolant temp sensor in the cylinder head. Not sure what thread it is though.

From AEM, I believe it's one year. From us on the harness side, it's 1 year free from manufacturer defects.

Alert: potential poached and attempted impersonated AEM EMS for the IS300 have been detected on the market. Buyer be aware. Recall that we have been doing this since 2006. Buy from the source. The originators...Dezod Motorsports.
