Originally posted by Tired2 I could be wrong, but I think that is a feature of MS3, a "finer" table just around Idle that it switches to under certain conditions. You won't need it anyway probably, I think I read that it was for trying to tune in cams that don't want to idle nicely.

Yeah, I will just keep an eye on what bins I am in during which stages of idle. Thanks, I will let you guys know how it goes...

Quick update...

I kept and eye on the bins and tweaked the VE table a tad bit... Worked so far! The car has been running nice... Once it is warm I am much more confident driving it and it is feeling similar to stock ECU. Still fine tuning the VE table at the top end (haven't been able to make many ramp runs).

Quick question...

During warm up... The car idles smooth (no oscillation). Starts at around 1200/1300 RPM (depending on temperature) and slowly creeps down with coolant temps rising... Where I get into trouble is when the coolant temp kicks the idle advance. Let's say idle advance is set at 160. When the temp hits 160, the advance kicks in. And then the PID freaks out and oscillates. The only way I am able to get out of it is to tweak the PID gains (lower them slightly) until it stops oscillating.

Do I just keep repeating this every warmup cycle until it doesnt oscillate when idle advance kicks in or am I doing something wrong?

Check out around the 426 second mark on this log:

Notice the drop in advance to 6 and then the oscillation begins...

Any ideas?
