Just put to gether Ls/vtec so not using knocksensor. I have not chipped the ecu yet so i have a code 23(knocksensor).
The question is.....When every thing is lined up at top dead center, cams are set correct and everything looks great, why when I start the car shine the timming light on the crank it is perfect and when i shine it on the cam gears the exhaust is fine but the intake is like 2 teeth off ?
I then turn the car off turn the crank with a wrench until the gears are pointing towards each other and they are dead on, scratching my head but, is this normal?

please let me know
Justin

 

the ecu is doing the timing it sounds like youhave a p72 gsr ecu . the ecu is looking for the knock sensor that is why you get the codeand the car goes onto limp mode that retards the timing .the easy to fix it would be to try a p28 ecu it has no knock sensor but you will need to up the rev limit ok

 

I have an rare obd0 XSI ecu cause it is a B16a and i just got lucky with the ecu
