nope still the same

a little update - got off knocking sensor connector (it was real pain - couldnt get my hand on it) - it is tarnished as hell, maybe thats the reason (hope so). I'll clean it and do test ride.

Actually Im pretty sure now it is because knock sensor, all symptoms match - jumping rpm's, too much fuel, problems with ignition timing and I got error 34 on ecu - knock sensor send signal to ECU which gives more fuel and retards timing for safety. The possibilities are:
1. broken knock sensor
2 ...

Got the same issue! I've just mounted h-dev stage 3 chip with whole setup. Has some problems with air leaks, needed new ECU etc and now Im in quite the same place.

When engine is warmed up Idle RPMs jumps betw 500-1200

Got problems with timing - once I've set it to 15deg and started the engine ...
