Default Okay this scares me

Looking through a log I made tonight. At 150K map I am commanding 11.75 (Boost Enrich) in the tune. 6000 rpm, 7psi boost and I'm at 12.7 commanded and actual. It does fall into place right after this but damn a bit late. Is this some sort of lag or something. I don't likey.

post up a pic of your power enrichment tab. Specifically all of the enablers.

I assumed this value would ramp the AFR faster, ONCE the AFR is commanded. In my example I am not commanding the 11.75 that is tuned.

kill the TQ enable. Zero that out. Not that you aren't meeting it, and not that the TQ enable is the issue, you are obviously in PE, hence the 12.72 commanded AFR, but why bother with it? I am not to sure the enrich rate will help you change your commanded, just like you said. I may be wrong, enrich may be how long it takes to change the commanded. But I'd be looking for more specific things keeping you from commanded. Post a screen shot of both PE and BE tables. I see your cold/hot select is at 220. Are you running at 220? I doubt it, just curious.

Lower the MAP enable about 5 kpa and get rid of the torque enable. Also max out that enrich rate, being boosted, you want it to ramp in to power enrich as soon as possible. This way you know you will meet PE as soon as you need it to. What does your TPS enable table look like?

I do not know what you are talking about. But, here is a little secret. If you hold the the ALT key down and press the PRINT SCREEN button on the keyboard, it will only copy the active dialog box.
