Timing problem? 4agte

[dickhead]

HOLY SHIT! Sorted! the wire from the knock sensor wasn't connected to the ecu, holy shit it goes good now!!
Thanks guys for all the help!!!!!
I CANT BELIEVE IT GOES GOOD!!
Does advancing the timing slightly past 10 degrees make any difference to performance?
Also, I have a bigport bluetop head that i've ported and had plained, was thinking about putting this on...? Would that make much difference?
ahhhh :):):):):):):):):)

If you advance it too far the knock sensor detects knockand the ECU reatrds it all again.
Sometimes just less than factory is best, sometimes bang on is best, some models go better again with more.

Yea those cars go like crap with no knock sensor eh? Its happened to me and they dont go anywhere

Good to see its going all good.

Air temp sensor is no biggy, TPS is easy to callibrate, just read that thread and move the venier adjustment on where it screws. AFM error... hmmmmm maybe take the battery off for a while (resets the ecu) and put it back on and re-check the codes.

10 degrees is good, 8 is probably better. Only advance past 10 if you'll dropped the compression ratio.

what sort of head to you have on the car now? I doubt a bigport head will be better than a smallport head (map sensor 4agze). If anything just use the bluetop cams on the smallport head.

sweet, i'm pretty sure its the standard gze head. I thought bigger ports would be better? plus its been skimmed,would a higher comp ration be better?

some guy on the garagedori forum is making 283 rwkw using bigport head

other extensive mods but still....

Unless your going for big power stick with the smallport head, it'll be more responsive and make more power to a certain point, however bigport will have higher maximum power capacity. (unless you port the smallport motor)
