AutoVE tuning newly boosted car

[Jim_PA]

Would I be better off with an e38 PCM? It seems like they have several problems of their own. Maybe a GMPP PCM?

It would be nice to get rid of the TAC module and my stand-alone reverse lockout controller.

Most recent tune and log attached.

When does PE "turn off" Or is it always on once the PE enable conditions are met?

PE is active until any one of it's enabling conditions go away.

Are you getting a MAF DTC...?

P0102 and P1637 are currently read from the scanner

Try the attached tune file.

also log KR.

[Jim_PA]

Try the attached tune file.

also log KR.

Seems to run pretty well, seeing some KR in the higher maps where I think timing seems somewhat conservative?

Here's a really short log, I will have a much better one tomorrow.

Appreciate the help!!

I did pull spark timing down a little... with boost you have to run less timing.

What fuel are you running (octane rating)...?

93 Octane -- It's running pretty good!

Attached is a much better log...LS1B_0137.efi

I did alter the boost timing table to this:
0.507813
6.738281
7.773438
8.808594
9.296875
9.785156
10.292969
10.781250
11.269531
11.757813
12.265625
12.753906
13.242188
13.730469
14.238281
14.726563
15.214844
15.703125
16.191406

Looks much better...

there are two places in the log at steady throttle (approximately) where wideband indicates lean... post your new tune file.

also there are twp places on boost up where some small KR occurs, it doesn't look real, so I think it's ok.

Oddly, the car suddenly doesn't want to idle before it's warmed up with the AC is on. Hit key, fires up, and just falls down and dies. Have to either keep it running with the pedal or turn the AC off. Hasn't done that before, but nothing should have changed that.

I added some extra idle airflow and selectively multiplied 50% error correction -- It was still stumbling 1500-2000 in most gears when you get into the throttle.

Will flash this file tonight and see how it goes tomorrow.
