ok ok i know there's a lot of these out there. but its hard to get a straight answer. i know what i need. except the ecu! i need to keep it obd2 cause i have emissions. is there any ecu i can use that basically plug and play besides wiring the vtec in?

 

Any OBD2 vtec computer will work, but try to get one for the head you are going to use.

 

No obd2 ecu will properly run a b20 with vtec head. Being a tuner I can't believe I'm gonna say this but, I think your stock ecu and a vafc is your best bet. Fuel should be pretty spot on before the vtec crossover, then you will have to add fuel after the vtec point.

Sticker bomb is right that they will all run it, but none of them will provide enough fuel.

 

so with the stock ecu and the vafc, how would you wire in the vtec??

 

The vtec wire from the vafc will activate the solenoid. Back before obd1 chipping that's how a lot of us ran vtec engines in non vtec cars.

 

godpeedcrv has that set up... vafc and oem ecu on his auto b20V...
look for his write up, i really didnt catch how he wired the vtec but im assuming it should be
integrated w/ the vafc or even manually by using those shiftlight module and tapping the signal
from there... good luck!

 

whos write up qwrty?
