ok i have 94 ls w/ gsr swap chipped ecu, i/h/e. and when i drive my car i get up to the 5500 rpm range and my check engine light comes on and then cant rev past 3500 could it be i have it wired backwards or would that not affect it? let me know what you guys think it could be?

 

pull the code first...Oil pressure switch code probably...faulty solenoid, or dirty...just pull the code then post again

 

i get code 16 and 21, but the engine is '01 and has 88k on it and nothing was wrong with engine b4 just smashed!!!! but gonna swap out a few injectors or is there a way to see which 1 it is? any way of testing the vtec ??

 

The IAB will not affect the operation of the ECU, as it provides no feedback. Check the Helm manual for the trouble shooting flow charts for your codes. If you need one, search google for "hondahookup manuals".
