Default 1989 Supra 7M-GTE - AEM EMS

This car is running 550cc injectors, 57trim wheel, full exhaust, and was running the stock ECU with a Lexus AFM, SAFC, and an AEM Tru-Boost controller. I upgraded it to an AEM EMS system with a 3bar MAP sensor and AEM wideband. Also, the car has aftermarket forged pistons running stock compression, in a freshened otherwise stock bottom end.

On the stock ECU we quickly found the stock ECU's boost limit and the resultant power output left alot to be desired... So in came the AEM EMS. The only other changes were the deletion of the AFM and adjustments to the boost controller.

Before (stock ECU, AFM, SAFC) / After: (AEM EMS)
