Extremely high LTFT trim. What's happening ?
It mostly happens during idle. I know normally it should be +/- 10% but this is way off. Anyone have any idea?
I have oft stage 2+ E85 tune . OFT catless uel header, Test pipe, N1 cat back, K&N drop in filter. Pretty much it. I would definitely appreciate any help I can get! Thank you! I have tried to reflash it, and it doesn't work. P0171 code showed up. As well as another code too but I forgot what code it was before I reflashed it.   Sent from my SM-N960U1 using Tapatalk |

Exhaust leak near the header, maybe?

Your car must be stupid loud.
Anyway, did this suddenly happen or did you just flash it for the first time and this is happening? Need a bit more backstory. High LTFT can be caused by a few things. Where did you get this tune from? OFT does not supply an off the shelf e85 tune for 17+ cars as far as I was aware. The only way to get it is to have one modified from a different calid. EDIT: Here you go. Same issue as you are describing. https://www.ft86club.com/forums/show...=121767&page=3 Fix: https://www.ft86club.com/forums/show...1&postcount=36

Problem fixed it was all because of big ass crack from the beginning of the header all the way to the pipe. Also, it crackked before the o2 sensor.
