Default AFR Lean safety on map 4 - 10-06-2021, 02:25 PM

Hi all, finally found an e85 pump near me so I got a mix of 93 and e85 (think around e30) and the car was running great for a while and all the sudden it dropped to map 0. AFR Lean safety :/. what went wrong? How can I fix it? Log is too https://showbox.bio/ https://tutuapp.uno/ https://vidmate.cool/ long to post but I’ll try to get a map 4 log if it’s advised.

Get a 3rd or 4th gear log from 2k to redline at wide open throttle, in MAP 4, with traction control off for proper review. Thanks!

If I was a betting man, you mixed a bit too much E. very common if you don't have a tester or the fuel it sensor. Fuel pump can't keep up with the demand. In addition, Map 4 is pretty heavy on boost, especially without a proper octane boost. I would start with Map2 or Map3 before you try map 4 again and let someone here look at it.
