How bad are my timing corrections?
https://datazap.me/u/phax/3rd-gear-p...24-25-26-27-28
2013 BMW 135i N55 MHD Stage 2+ ACN 91 VRSF 7" HD FMIC VRSF downpipe VRSF chargepipe Berk catback exhaust 3rd gear pull. New Delphi coils and Bosch spark plugs gapped to 0.022". Walnut blasting done. If these corrections are bad, what do you guys think might be causing it? Aggressive tune? Hardware? Fuel injectors? Bad Cali fuel? |

1. It seems even on the factory tune timing corrections happen frequently 2. You are in CA; the gas is likely what is giving you so many My personal solution was to run the 91oct map while continuing to use 93oct gas. The timing corrections have decreased quite a bit, albeit they still happen, but rarely beyond -3. Additionally it is infrequently on seemingly random cylinders most of the time. Also, some gas stations seem to be better than others from my experience. If you can, get your hands on higher octane gas and you can test the bad gas theory easily. if your unable to find good pump gas you may be able to get a 5 gallon can of 96oct race gas. |

Put some ethanol in (2-4gal) drive ~15 miles and relog. My bet is it will be pretty clean.
