Hey man, you should take another log with both lambda bank AFRs and STFT 1 & 2 and LTFT 1 & 2. Without seeing those, it is sorta of hard to help. Having your AFR at 13 is a bit high, but it'll be hard to point you in the right direction without the rest of that information.

Got it will do. I went back to my 93 octane ots map the car had kept feeling like misfire during wot. Its been my second fill up drained all the gas and the misfire is gone at wot.

I would also recommend on a E30 map you show the WGDC bank 1 and 2. These are all fueling metrics that will help us see the condition of your fuel pumps, trims, AFR, etc. Did you just get the car?

No offense…
But are you sure you had the correct amount of ethanol?

I had the same issues when I first went e30 with mhd…
What I learned through logging and those that knew better.

1. Make sure you have fuel lines capable of handling ethanol
2. Make sure you know your mix, sometimes you have to drive around and let fuel mix
3. Get a ethanol reader of some sort, only if you want peace of mind to know what your mix is
4. Make sure your fuel system is running efficiently…fuel pressure regulator, lpfp, hpfp, injectors.

Maybe you know all of this…no offense if Im just preaching here!
