So I have a 2006 tC thats supercharged and im currently running the TRD reflashed ECU with the NST 9.5 psi pulleys and a few other bolt on mods. I like to leave room to expand just incase I ever want to upgrade my pulleys again and run more boost.



My question is even though my ECU has been reflashed, can I run an AEM FI/C with the reflashed ECU or will I have to buy a stock ECU then go the FI/C route??

 

Shiznami, you can try adding the fi/c to your supercharged ecu, its just more compliated this way because the s/c ecu is already modified and may act funny.

 

Buy a junkyard stock ECU, then add the FIC to it.

 

X2, case closed. $60 for ecu.

 

You do not need a stock ecu. I believe the AEM F/IC allows you to work together with the trd reflash so you do not need a stock ecu.

From AEM's website: "This system works parallel to the factory ECU preventing tuning limitations due to complex factory timing patterns." "http://www.aemelectronics.com/engine-management-systems-9/fuel-ignition-controller-f-ic-12/"
