I got my PBD e85 tune worked out and the car runs great just wanted to know what you guys are reading on the dash for e85 afr's. At wide open throttle ill see 8.1-8.5 afr's. Is that pretty normal ? thank you in advance.

thats my run showing 8.1-8.2

Thats a pretty good afr number for an NA car on E85

Thank you, i did several data logs going back and forth with pbd. Trevor there was pretty specific. Only issue i have is after the last tune the car surges forward if i slightly tap the gas or even when im slowing down it will seem like it will shoot forward for a split second and even if im on the brakes i have to slam it and triggers abs, seems like its downshifting to accelerate. Mostly happens here and there at low speeds but when it gets bad its bad.

I believe Ive seen someone else describe the same situation as you are having with their car. Ill see if I can dig it up
