Thanks D. I'm really happy with the project. Mostly now I just want to make sure it's bullet-proof. Then it's on to bigger and faster things I guess. This train doesn't stop does it?
Never. |

FanTASTIC job Leroy! You should be proud. Job well done. Now you need to get a 2.7t so you can go save the completely stalled 2.7t community project  |

Logs really good.
It compares well to the stage 1 I have on my BFB running around 150maf grams as well, altough I'm guessing its quite cold where you are at the moment? During the summer when I was logging mine I was only ending up with 12 degrees timing at the top end compared to your 20 and that was on 99ron fuel as well, IATS were up to 40c though on the run...

Yes It was -2*C ambient last night. I didn't consider the effect of air temp on timing advance. Is there a correct way to tune timing for temperature variance? I know the ECU will pull timing if there is knock, but it would be cool to prevent pull if possible. |

Here's the *finished* file. I'm sure there will be 25 more revisions after this one, but it's pretty much all I can do with stock equipment. I'm going to re-name the original file in the OP "stock" and put the tuned file here, so anyone who wants it will hopefully read through the thread.
This is the 24th version of this file on my car, and that's only counting the versions that were different enough to warrant keeping the old one for comparison. It's been a labour of love, and I'm very greatful to all the great people on this forum who have helped me to learn.
I'm going to continue to "refine" the file and if I see small improvements, I'll post them.

Kftarx is about it which is load based. So it pulls load when temps rise. |

Leroy et al., thank you. This thread is great; fantastic tool for learning! I have a couple of questions based on the latest bin you posted, anyone please feel free to jump in. 1. Is it necessary to adjust KFMDS, KFZWOP, and KFZWOP2 based on the change made to KFMIOP load axis as it is shared? 2. The bin doesn't include the P1681 Work around, is the consensus still that it should be included for all 2004+ cars? |

ABSOLUTELY! The easiest way by far is to just move columns/rows around, so you don't have to re-interpolate stuff. This is generally the case whenever you change axis data that is shared.. trouble is, an incomplete mappack might not have all the maps that share a given axis, so it can be a bit of guessing game, unless you are good with IDA. 2. The bin doesn't include the P1681 Work around, is the consensus still that it should be included for all 2004+ cars?
Maybe? hopefully others can chime in on this, I have no personal experience on this topic  BTW I can't express how happy I am about this thread. Really. Truly. Thanks everybody! |

Anything >03 should include the P1681 workaround IMO. It doesn't ALWAYS happen, but when it does, it can ruin your day.
In sw 368072, it is 0x6B3AE
in sw 369307, it is 0x6B598
2D--->0D to kill the code.
I too am pleased at the direction of this thread. I think this is 100x better than the alternative. I'm going to simplify it and clean it up at some point once we have a concrete conclusion. I'd really like to see some logs of another car or two with the same file before we call it conclusive.

I didn't adjust any of the other maps that share the KFMIOP load axis. Oops. Like I said, 25 more revisions ahead. Also, the P1681 work around... this will avoid no start condition after reading back the file with nef?? I guess it's a good idea to do the map adjustments for the KF group and re-log just to check for any other ill effects. I've already started "tweaking" a few things here and there on the file anyways.....What does KFMDS do? I don't have it in xdf. Where might I find it?

I totally agree about cleaning this up. I was actually thinking of making a "walk-through" including all steps and links to theory on how to make the Stage 1 file. Then it could just be a closed thread "intro to tuning me7.5", leaving this thread for discussion and future optimizing of the file. This would be a large undertaking though, so it might take me a while. And yes, we need some logs on other cars, with different conditions than mine. I've got the advantage of cool ambient temps and decent gas at the pump. Would be good to troubleshoot and show solutions for other people's cars. Cheers everyone, lets make this great. |

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
No need to lean it up top. You'll find little gain by requesting .84 lambda. Keeping it at .82 will keep things cool and safe with little to no sacrifice in the power curve. |

I've ported your maps to an 018CH bin and looking to do some logs, what variables should I log? I've taken it for a quick drive and even not going above 3/4 throttle it feels great, but I wanna know for sure everything's safe before I really push it.
As an aside, I edited the KFZWOPs to reflect the changed axis, wanna know if I did the right thing. I moved each of the bottom 3 rows up by 1 and kept the bottom row the same. Is that fine or should I try to somehow extrapolate the bottom row values based on the previous 2-3 rows?
Also, what's the logic behind the LAMFA axis changes? Why compress the RPM axis? More mid-RPM resolution? Why stretch out the requested torque axis in the areas where it's all 1 (under 90)? Wouldn't it be better to have more resolution in the upper load range where the values aren't 1?
I apologize if these questions are stupid or have been answered in the thread, I'm just starting to learn this stuff.

Yeah, this was a bad suggestion on my part. |

The idea is to get lamfa to be as smooth as possible in areas where it will be changing a lot. I haven't looked carefully at the lamfa for this project lately, so I can't comment if it is done correctly, but from leroy's logs, the results seem good, compared to other implementations of LAMFA that i've seen (including some i've done myself lol) I apologize if these questions are stupid or have been answered in the thread, I'm just starting to learn this stuff.
They are all EXCELLENT questions, no apologies needed! |
