Here are my God awful logs before switching tuners... Notice the -5 knock events. Cruising, WOT, everywhere, didn't matter.

Got a new file in over the weekend. Still a tad of knock but much better. Knocked once over a two mile drive to work. at low rpms low throttle. Logs are attached. @mad_sb here is a pic of the IAM value resetting from .94 from before I cranked the key to .7 on start up.

I will need to take a look. Here is the thing. I flashed back to the old tune, prior to my last one, and that issue is gone, so seems to be a tune issue? I will post logs of the "old" tune later today. |

It might have something to do with your tune and intake combo.

Site only accepts .zip, what people do is post a .csv, change the extension to .zip and then you download it, change it to .csv and it opens in your computer. Might be, true but since his "old tune" does not show the behavior seems to be isolated to that specific tune.

True, it's somehing changed in the tune, but i had a similar issue in the past at a lower rpm. It was intake related, but only happened at wot, and caused the same issues. My tuner later tuned it out.

Exactly what i was thinking. I was really hoping it was a tune issue and not an engine, connection, etc.. issue. I went through all the engine double checking all my hoses, connections etc. Everything looked solid and secure... So my next thought was it was that wacky tune. Flashed back and sure enough, running much better. I will post logs soon, but from what i saw running the old tune yesterday, my knock correction was at least only a -2 at the most. So a bit of an improvement. |

Its weird, and something i dont notice all the time, especially since i dont really drive around WOT usually. Only noticed while doing the datalogs... Got an appointment on Monday with my tuner, hopefully we can resolve all this, if not, its off to Toni at FA20 for a remote tune. |

A little bit....what would you consider a little bit? My tuner has had my car for around 20 days total. Shouldnt that be enough time to work out any bugs and get it tuned properly? Or is this car just too new?
My tuner has actually said he doesnt really want to tune twins anymore after working on mine and a couple others...says they are just too hard to tune, and the software is a pain. Is the consensus that this is true? Or is my tuner maybe just not a good fit for me and my car? Thoughts. Hope to not derail the topic too much. Last edited by gdrider77; 10-02-2013 at 06:26 PM. |

Tuner is not a good fit for your car or any of the newer management systems. They are not a difficult car to tune, especially if you are not doing it remotely.
