Hi, wonder if someone could look into my logs. The timing is not stable, new coils and ngk 95770 gapped to 0.6mm.
Slight hesitation at high rpms.. Bmw 435i 2015 ewg with 11200miles Vrsf catless dp Vrsf 5" hd Intercooler Latest bm3 91 octane map https://www.bootmod3.net/log?id=5f81...90c66c1601b315 https://www.bootmod3.net/log?id=5f81...90c66b7ec5f86b |

Aside from that, boost control, fuel trims, etc, all look good. You do have a throttle closure in one log but not the other so it could have been a fluke. |

I run 91 octane fuel with 5% in it I have tried different fuel stations but all are the same. When i put stock tune in the timings har 100% even. Here is a pull on stage 1 93 ron to compare with https://www.bootmod3.net/log?id=5f22...0b4326f0572a0f |

There's plenty of people here that have trouble getting clean/even timing on the 91 map even running 93 octane pump gas. The pursuit of perfect timing will only drive you crazy; don't expect to have 100% even timing across all cylinders unless you are running fuel with significantly higher octane than the tune you are running (or have WMI, etc). The fact that you have even timing on the stock map is likely just because its running much less boost. It doesn't mean there's a problem with the stage 1 map causing the timing to be like that, its likely just that your fuel quality cant support the boost and timing targets of the stage 1 map. If you email PTF support, they will probably tell you to run the ACN map. I'm not sure what else you are looking for here. I don't see anything else in the logs that you suggest an underlying issue with the tune or car. You can always email PTF to confirm. |

I just tought is was more serious problem with all the timing corrections when I have changed the plugs and coils. Can I increase the octane a bit with 1-2litres of E85 to see if the timings Will be better? |

Yes, adding some E85 is common to improve octane and timing. 1-2L is basically negligible when added to a full tank of gas... you will need more like 1-2 gallons to probably make any difference at all. If you are unsure about your ethanol content, i suggest getting a kit like the link below or equivalent to test both your pump gas and E85 for E% to take some guesswork out. Otherwise, just add 2 gallons, fill the rest with pump gas, log again, and watch your timing and fuel trims. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 |

I will definitely invest in a E85 tester kit since I am interested in bm3 e30 map |
