Start enrichment at say, 70% pedal position and ramp towards 100%?
Richest at peak load. You want AFR to decrease as boost increases. Sort of inverse. Don't go too rich too soon. It might not matter on a K03, but that can hurt spool. |

on the rpm axis.
Agreed, if you do it on the pedal axis you'll get terrible gas mileage. Also, doing it via pedal input doesn't even remotely compensate for time based smoothing  |

Definitely not.
you don't want to add any fuel anywhere except for last column.

Disagree with nye. 90 percent should request enrichment. Just not the same as 100 percent, and not as early.

works for me, but enriching in 70% makes no sense  |

You're a prince! Now I understand what you guys meant  Before I had only 1 lambda and .85 lambda, the latter was the ENTIRE last two columns at any rpm above 1000. What I needed to try is smooth out the transition between 1 lambda and maximum enrichment as rpm increases, still in these two rows only. We'll see how it goes! |

Agreed. LAMFA first, BUT:
From comparing lamfaw and lamfaws, TLAFA seems to be zeroed properly.
ZK is getting there. We aren't that far off as far as LAMFA goes... i think it would be safe to start addressing BTS onset as well, even now.
Looks like IDC is maxed as soon as BTS comes in, but we're still close to requested, so we aren't entirely f'd. Might want to tone down req load near redline anyway.
nyet: You think i should ramp down ldrxn a bit more towards redline? |

I think you will end up needing something like this in order to get lamdba where you want it at .85 with those time delays active 1k .80 3k .76 4k .79 5k .83 6k .84 |

Actually, with stock ZK you don't really  It will do the smoothing for you ... but the concept is correct. In any case, you may actually HAVE to make it a cliff if you keep ZK stock. nyet: You think i should ramp down ldrxn a bit more towards redline?
Let's hold off on that until we see what IDC looks like w/o BTS |

Log from this morning, with aef's lambda values and a *very* slight ldrxn decrease through redline (sorry nyet, already logged before I caught your post). Let me know what you think

I want to see an AFR of 12.5 at 2500rpm. I think LAMFA is coming in too late. If that doesn't knock EGT's down a bit, then it's time to raise the threshold for BTS enrichment.

I guess I need to alter zklamfaw to allow faster onset of lamfa fuel map? Is this parameter a map or scalar? I saw you posted the address a few pages back.
Or maybe just try to cludge the numbers in the lamfa table and log until it works? I'm starting to think I should run the stock file for this road trip if ive got lean burn issues

No. What you have there is reasonably safe, just not ideal.
Nye will chime in.
