I'm going to need to compare with a log from another car to eliminate the possibility of a sensor or other flaw on my hardware. Until then I'm just gonna drive it.
how did you work put your KFMIRL? theres a whole chunk in the 3000-5000 rpm range 70-85 % that is 160, I don't belive this will help you... Have you tried the 225bhp KFMIRL/IOP..? |

I put those 160's in the KFMIRL in areas where I wanted more load than the stock map requested. These were the areas (at the time) that had less requested load than the maximum allowed by LDRXN. I haven't tried the TT 225bhp KFMIRL/IOP yet, but I might as well to see if it's better/worse than what I have. Once the snow is cleared (maybe on the weekend) I'll try this out. Could you send me the TT file/xdf you use for comparison? |

I have used this TT 225bhp BAM ols posted here before clickThanks Rich  . Unfortunately I got a message from SB_GLI saying he tried the 225 IRL/IOP on his jetta and it wasn't very good, part-throttle issues and such. I went back to the IRL and IOP tables and re-did the previous modifications with a bit more patience and smoother transitions etc. I also re-did the KFZWIOP1/2 tables as well. I'll log tomorrow hopefully, and if it's any better than before I'll put the log up for further evaluation. |

yes.  Had a lot of part throttle issues with it. Axis were set correctly. |

It was probably more due to the 8psi cracking pressure of my frankenturbo wastegate. too much boost @ part throttle, too much load, bottom dropped out on the ignition advance. I've had better luck with maps I made myself than the tt maps. |

I flashed the changes I made to IRL/IOP/KFZWIOP(1&2) and logged the file. A bit smoother through the pull maybe? The log looks ok, except.....
The big timing swings are still showing up. I can't say that the engine isn't performing, but these timing swings are getting annoying. I expect to see 2-4*, but 6*+ in some areas is driving me nuts when I review the logs.
any ideas?

If you look at my logs from a few pages back I'm getting even worse timing swings, so I doubt it's a hardware issue with your setup. That being said, could you post the changes you've made recently?
Also, just tried TT225 KFMIRL/IOP and it's perfectly fine, no part throttle issues. Maybe a bit of bucking at low very RPM/low throttle, but that could be because I have a ton of drivetrain slop. I'll try to get some logs soon, I'll post them in the other thread when I do.

Here's a few pictures of the tables I modified for the last log. I smoothed out the KFMIRL values in the 75, 80 and 85 columns, with the 75 column closer to stock. On a second look, I didn't do anything to KFMIOP compared with the Tuned_v3 file. The KFZWOP1/2 tables were modified to reflect the new 160 load row: I followed the curve in graph view and ended up lowering the values by 2.25* for KFZWOP1 and 1.5* for KFZWOP2 in the 160-load row. I think I'll just try the 225 values. Might as well. |

Just a suggestion but have you tried increasing the timing values slightly, as the only thing I can think off is that I run 1-3cf where as you have 0 |

Yeah, the timing is increased vs stock. I had a bit more timing in it before I modified IOP/IRL to allow more requested load, and when I got a few more PSI boost out of it the timing corrections started. I pulled timing back in those areas a bit to clean it up. I'm also running 94 octane, so I didn't want to push too far if someone running this can only get 91.

Ok, I tried the 225 KMFIRL/KMFIOP values and the results so far are good.
The timing swings are much less, average about 4* through the area that used to get 6* (4000rpm up). Drivablility (so far) is fine. I'm going to run this file a bit more and do some more logs. Not sure why the timing swings are better, but they're better and that's good enough for me.
Here's the log from this morning, I'll post the file soon if it works out. Might put a bit more timing up top and see what comes back.

mifa is still awful close to miist.... if you can get mifa up a bunch more relative to miist, you might see this clear up.
I'd underscale the MAF a touch maybe? Just to experiment? Your actual load is consistently over requested load.
THIS IS JUST A GUESS! Don't read anything into it heh. Trying to figure out the source of your torque intervention...
