Omg I forgot: turbocharged my 2.4 but didn't swap ECU

[TopDowngst0803]

Ok I turbo charged my 2.4L Spyder.....Everything is great an all but I just read that I was supposed to change my Non turbo ECU for a GST one. I never did that, so im guessin the computer i have is only programmed to give enough gas to the old 275cc high impedence injectors. I have a 255 walbro, an 450cc injectors. But i feel like im not gettin nearly enough gas, am i supposed to change the ECU or am i wrong here? Anyone that knows ### im talkin about an can help i would appreciate it.

You need a turbo ecu, the fuel maps are gonna be different. Try to find a Eprom ECU and get dsmlink or a keydiver chip to.

Wow, please don't drive the car until you get this straightened out.

You are running really lean and that is very dangerous. Also, I would look into an AFPR for that 255lph FP.

Ditto to everything Spyderturbo007 said. If you cherrish your engine, don't drive it till you fix your ECU and fuel pressure problems.

I have a MAF Translator installed too, do i still need that GST ECU?

 

[Spooling99]

Yes cause the lowest setting you can compensate your injectors for on that is 450s. Your gonna need a turbo ecu because the fuel maps and octane value is gonna be different. Just buy a Eprom off the classifieds and call it a day. You'll be much happier later on.

* seeing that your 2g, FFWD connection has socketed ecu's for 250$. Might want to check that out.

I second Spoolin99 on the FFWD Eprom ECU. Bought mine from there, it looks like every part was went over and inspected as needed.
