ANY leak after the MAF will cause your issue. You talking about where the intake pipe connects to throttle body with the rubber coupler? |

If the exhaust and intake piping doesn't do it, I don't know what to do. |

A Leak at the header to engine gasket could effect LTFT some, but not that bad. Maybe 5-20% depending on how bad the leak is. But if it’s bad enough to effect it 10%+ you should be able to hear it pretty obviously. |

here's my latest log on E85. It appears that I'm running rich now, right? Still got the P0171 code. |

A little history...
Been running Delicious Tune stage 2 (93 octane) for several months now with no issues. Decided to go with the FlexFuel BT kit and have gotten some revised tunes for it based on that install. However, once I got the ok to add E85, I wanted till my gas light came on then added E85 - nearly a full tank. That's when it started - hesitating and bogging - felt like the a/c was being turned on and off or someone had been jerking the parking brake. I really only feel it under 3k rpm, partial and full throttle. I have a silicone inlet tube, afe panel air filter, FT86SF catted UEL header. Again, it was running fine on 93. Only started having issues on E85. I've attached some logs with multiple scenarios. Not sure if it's the tune or the E85. https://datazap.me/u/ba9092/log-1563...?log=2&data=22 |

Anyway you are quite rich in some areas. Around 5400 rpm you command afr 12.24 and measure 11.25.. thus 100-(11.25/12.24)*100 = 8.1 means you are 8.1% + 2% of negative ltft richier. 10% is quite much and you have to reflect it in your maf scaling. |

Currently running stage 2+ OFT tune with 93 octane gas from Canada. Only mods are catless headers, drop in apexi air filter and a catback.
I can't seem to get anywhere close to 1 IAM. After driving at least 20 minutes and even driving the car hard and going through the rev ranges, I can't get IAM to move. The highest I've seen it is .78, I've tried 94 and 93 from two different gas stations. Any reason the cause of this could be? Is it purely based on bad gas? Anything else that's alarming based on the log below? https://datazap.me/u/lc300/oft-v4 Last edited by lc300; 08-08-2019 at 06:55 AM. |

Any intake mods? Does IAM drop at all or just not go up? |
