8.8 is super rich...I've ran e85 on my mazdaspeed 3 and I never changed my target AFR based on fuel... I would still want to hit 11.7 - 11.8 even on my corn tune.On E85??

Educate yourself a bit on data logging and what e85 is. Not sure how accurate the stock gauge is, but 8.8 a/f is more then super rich. It could actually cause damage to your motor. Put the 93 octane tune back in until you can get it sorted out. That is where the missing power is at.On E85??
Agreed. I just went with the pack when it was released :/Educate yourself a bit on data logging and what e85 is. Not sure how accurate the stock gauge is, but 8.8 a/f is more then super rich.

stoich at idle (and for part throttle) is lambda 1 which for E85 is 9.85. 10:1 is around E75 probably.Whats ideal for idle and wot?
Idle I see 10.1-10.5 I assume the quality of e85 would affect that. And also affect the wot values if its not pure e85 right. That's the whole FF principal??
it reads correctly on a flex fuel tune, not excessively rich. pure E85 should show 9.85 on the stock gauge at idle and part throttle.Pretty sure on E85 the stock gauge reads excessively rich.
no he's not.Contact Lund and tell them you're running super rich on your e85 tune..I'm sure they'll sort you out.
incorrect. that's a great way to learn about preignition. best power lambda for ethanol is RICHER than gasoline.E85 can run leaner than 93 at wot
Deleted my post due to misinformation...I didn't realize the wideband read the AFRs like thatno he's not.
they read lambda. AFR is always a calculation off lambda, which means there is always room for error in a calculation.Deleted my post due to misinformation...I didn't realize the wideband read the AFRs like that
Running the same E85 as another local here running a Bama E85 tune.. 117mph tune and intake only. Don't think its fuel quality. WOT A/F on 93 is 11.2... think its fairly rich to say the least.start with datalogging.
there could be a million things going on , fuel quality could be crap, could be getting false knock, etc....
first place to start is always with vendor and lund on stuff like this.
Sick03L,I'm a little disappointed to say the least. After seeing all these cars running 115-117mph with a FF tune and intake only..... this is not my case.
Had some killer high 50 degree air last night down here in FL. Car consistently trapped 113.xx all night on E85. 2016 PP, with JLT, FF tune and CB.
2 BONE stock auto GTs with 3.55s were trapping 113 all night as well. Figured since I was not mashing shifts on the track due to wheel hop that I was leaving some mph on the table. Well I got to make a quite few pulls with one of the stock auto cars leaving the track..... with him having a passenger and 2 rims in the trunk I barley **** haired pulled on him ( Fender )
Im figuring there HAS to be power left in this tune and /or that my car is just an under performing pig from Ford.
Now the question is do I try to find a tuner to dyno tune this car here in FL or data log with the PITA xcal 4 and send logs to Lund for review. I don't even have a lap top lol.
