this same thing happened to me

the engine wasnt recognizing the higher CC of the new injectors....replace your factory MAP sensor with a 2 bar MAP sensor off an mr2 turbo or supra (depending on which ct26 turbo you're using)

i used the 3sgte 2 bar map out of mr2 turbo and it fixed my problem....i didnt run the car long on the new injectors but it still ran!


This will have absolutely NO effect on how the car idles. The stock map sensor will work just like a 2bar map sensor at idle. When you're boosting you'll either need a 2bar map, or check valves on the stock one, but this doesn't matter at idle.

Also, the engine will never 'recognize' the injectors, neither will the ECU. It will always assume you have the factory injectors, thats just how it is programmed. That is why you have the SAFC to fine tune the fuel curve and to compensate for different injectors.
