Hi mates,
I have some issues with MegaSquirt and I need some help.
It's MS-I v3.0 board, code 029v, runing fuel and spark, car is Proton Satria GTI - stock engine.

I've finally instaled MS in my car for good, but engine is not working OK on idle. I've tuned my AE and VE tables, spark table is partially tuned (low kpa part) and generally I'm very satisfied how the car is going. Nice pickup from low RPM and crazy respond at 4k RPM. But when i take my foot of the throttle and let it idle it becomes unstable. RPM is constantly going up and down and misfires occur. This stops only when i set my AFR to 12 or lower at idle. But idle should be lean, not so rich.
Running on 4 squirts/alternating...

So I've changed these things without improvement:
- new injectors
- new spark plugs and leads
- new fuel pressure regulator
- changed number of squirts and fire mode, tried changing VE and spark tables
- even tried the Alpha-N mode, same thing when trying to get stoichiometric or leaner
- checked all the connections, grounds, and power supply - everything OK



I'm going crazy, PLEASE if any of u know the solution help me...
I've attached a datalog so you can see what is happening...
