detonation/pre-ignition... HELP!!!
hey guy i need ur help bad!! im almost 100% sure im hearing detonation from my motor.. if i hold my revs at 4.000rmp my exhaust starts to pop like crazy.. also once i reset my ecu im only throwing a code 20 but then once i've started my car up and reved it a lil it throws the knock sensor..
ok this is my setup - 94 eg hatch 0BD2 b18c4 motor (same as a gsr motor but with lsd) OBD2 engine harness, OBD1 cabin (underdash harness) harness and a JDM OBD1 P72 ecu..
now im still running a OBD2 distributor, so could this possibly be the problem??
how can i fix this problem guys? wot do i have to do?
any help would be very much appreaciated... Thanx

Do you have an aftermarket exhaust? If so how large is the piping.
Detonation would be heard coming from the engine, your not going to hear it out your exhaust pipe.
If anything you could have a slight miss-fire thats causing a poping sound in your exhaust.
With a motor thats damn near stock, I seriously doubt your experiencing detonation.
