I recently was in the middle of installing a turbo on my car but ran out of time before the cold rainy months here so I want to go back to stock and wait for summer. My question is I installed 750cc injectors and removed the resistor box as it was not needed. I have a chipped p28 ECU but it has a turbo fuel map installed can I use that to tune the injectors back to stock or do I have to buy stock injectors and resistor box? I have the stock ECU installed right now for a F22b2 engine. Teach me to throw away stock parts! I dont have the injectors and the resistor box has been removed and thrown away. Can anyone install a street tune with that size injector? Thanks for looking.

 

I'd just buy an ECU for cheap from the junkyard and use that. They shouldn't be expensive at all.

 

I have the stock ECU for a f22b2 engine and I have a chipped p28 ECU. I was thinking the stock ECU wouldn't be able to compensate for the larger injectors.

 

Use the P28 and tune it to run the 750cc injectors in the stock engine, if you don't want to buy new injectors.

Or you could find 4 used high impedance 240cc injectors, throw them in with the P28 ECU and run it on an F22B2 tune for the winter.
