AFR help E85 watermeth supercharged

ZStalker505 · 03-22-2023, 10:04 PM

Looking for info please! I have a 630+whp supercharged e85 water meth 4bar map car. Car was tuned in FL it's now at 5300ft elevation. Had a local guy check out the car and he thinks it's running a little lean monitoring afr via ecutek app he thinks he saw it go to 12.3 wot said he thinks it should be 11.7 11.8. What's an opinion on that given the setup?

Given gas, E8, meth has different afr's I assume the readings are taking all that into account since the o2 sensors provide the afr.
WOT GAS 11.5-13.3 E 7.7-8.8 METH 5.1-5.8

I'm changing the pancake k&n to the soho intake and also looking at changing the borla (for sale)2.25 to atleast a full dual 2.5 since the headers go into 2.5 test pipes. What should an ideal afr be?
