Too bad there is nobody here with logging software that can log an APR car  Generally 15-16psi, IIRC. Here's a log from my allroad on APR 91 oct tune for comparison. |

Uh. 11 psi vs 16?
I don't think we should stop here for stage 1.
IMO we need to massage HBN, bring up peak req boost to 15 or so, possibly iron out the VVT load->boost wrinkles (i'm sure purists will cringe, but IMO I don't gaf), work on fueling, then timing.
hmmmm i thought we hit 14 psi my mistake, ill have to take another look.......i agree with you otherwise bring load up notch |

If we start breaking this down, is HBN an issue at this point? In Flyboy's last log (me7log_20141016_214741) I don't see HBN intervening. The corrected load follows rlmxko so it's most likely the KFTARX map, correct? Do we want to modify that map to at least keep our requested boost at lower temperatures? We should probably log frxta_w to see what it's doing. Even at stock boost levels I've had this cause throttle cut on cold days. |

Agreed on all points, after reviewing that log. I think before messing with LDRXN we really should consider flattening all the KFP maps 3krpm and up... makes tuning LDRXN much more sane. |

What does rlsol_w look like?
The requested load (rlsol_w) follows the corrected load (rlmax_w). It's included in the log I posted if you want to take a closer look. The math works out for the IAT correction factor. |

I've noticed a number of misfires at cylinder 5 in Jeff's latest logs (up to 11). Are these normal? |

The misfire is not unique to the Nef tune. I think it's caused by a poor fit on a phenolic spacer that I'm trying out. Oddly VCDS calls it out on a different cylinder, 4 I believe, even though it is in the same cylinder that it is occurring. It's most prevalent at idle.

Thanks for sharing the insight Jeff. It's good too know that it is not specific to the Nef tune. I also experienced a very similar phenomenon on a L-box except on VCDS is showing Cylinder #5 where Me7Logger shows #4 consistently lol... Would you say that it's most prevalent at idle AND only when the engine is warmed up / running in closed-loop? And so I guess this is caused by some type of leak at the intake manifold? Cheers! |

So this what im getting when adjusting boost and fueling im not sure as to why im not getting full boost but am absolute sure its not a boost leak (my other logs/tune show this) id like to continue to try to help but this is what im getting, if i load my other tune i see 17 psi and it follows requested......just trying to gain some momentum

Looks like his I-limit is too low. |

By that do you mean the input value of 191, or the axis at 191? If so how do you modify it ? |

I mean KFLDIMX is too low. |
