I am running 1.5 jz with 1jzgte ecu and 550cc injectors on the stock rail with the mapecu 2. I got a set 850cc rx7 sidefeed w sard adapters and I want to run these on my bored out stock rail and the mapecu 2. My main problem will I be able to control my 850cc with the 1jzgte ecu and map ecu 2, since this exceed the map ecu 2 recommendation? Your advice will be greatly appreciated.
