my guess is your LDRXN is set up wrong. request more load earlier.
It's not LDRXN, rlmx_w and rlmax_w look fine. What does rlsol_w look like? Definitely doesn't look like the problem is on the desired charge side to me. |

Boost is getting closer, I still need to tweak the VGT opening PSI and the N75 some more to dial back the boost spike.
Load and AFR chart shows fueling to still be retarded, but not totally leaning out now that I am not boosting to who knows where.
AND.............now that I have some other people to reference I am thinking my timing is really low.

You are requesting too much timing.
Check your timing retard.

I thought I was running pretty conservative. I know part of the reason is due to the lean spot.

yea sorry, didn't see that. DEFINITELY make actual AFR match requested fuel before going further. That should be the FIRST thing you fix, not the last  Don't BE LAZY HERE! It should be consistent regardless of boost levels. |

I am trying to not mess with the kfkhfm map at all. The map is set to all 1's right now since I am running the hpx in blow through. I think I might use one of my user inputs to my ZT-2 to log MAF voltage so I can see where the fueling is going off compared to the voltages at MAF and dial in the MAF better.

I went to my first MLHFM that I interpolated from the original HPX 30 point transfer function and original KRKTE and it got me a lot closer to where I needed to be.

Going through my last log of the night. Not too bad for a couple of revisions. Timing is still really conservative.

I am wondering how my car compares to the s4's given I am running a 2.8 5speed trans and 19" wheel/tire combo.

Well I run 3.4-3.5 fats with K04's however timing and boost is not fully dialed in yet (the car is 1800 kg including me). Of course britishturbo has been running way better fats than this with his single turbo and I guess he is still not ready with his tune.

That lean spot is likely because you are hitting the ps_w cap. |

I Kind of figured this was the case considering it was really lean right where the boost goes off the scale. Until I figure out the hack, I did what I have been doing to fix 22+psi weirdness. I scaled KFKHFM down in those areas and scaled KFLF up. |

2.8 FATS now at ~22psi of boost :-) I'm getting my tune a lot closer to where I want it now... And today my new MAF showed up... so I get to start over with my MAF too lol  |
