The E85 tunes are awesome. My car loves right at 33* of timing. Makes tons of airflow all the way to 7850 now, and I shift it at 8000 to drop back into peak tq. The 93 tunes are about 28* total advance in comparison and even in those situations, I'd always say you should blend to e20 at least...

More control with manual.

Bye

It’s been figured out since 2018 smart guy. We just choose not to do them because the majority of users out there struggle with understanding how to handle a flex setup with a defined learn trigger and a finite learning window. That’s also exacerbated by DFCO skewing learning in the lean...

I considered doing like a 13.00 afr tune and trying both 93 and E85 on it. Again it wont be full spark, but the stoich is close enough to the median that the fuel trims will compensate in either direction easily and you'd never know the difference. But I dont like the idea of a car adding fuel...

Robert Papini. Hes the tuner. Jon is great too with flex. Personally inferred flex has always been more of convenience and not performance. Since you are blending in most cases, you are not getting to full E levels and the car is never giving you full spark/power if set up correctly. If you...

I really dont get your hardon over the flex tune. But if you REALLY must have one, this person is the best at them. The best tuners are the ones you've never heard of, and Robert is one of those. Or Jon at Juggernaut. Both have flex tunes that are as good if not better than any straight E85...

If you stay stock mechanically, then no issue at all swapping back to the stock tune. And most of your knock protection is from e70+ anyway. So you would be safe there. I could do a closer to e70 stoich tune to get your fuel trims closer to zero if you know your local station is like e70. I...

It does happen, but I try to be as responsive as I can be. Im on a device or computer basically every waking hour, so its virtually impossible for me to miss a notification - sad I know. My kids are mostly grown and the wife is very happy with the life I provide, so they are all very...

No we arent doing flex tunes. Im with P1. Flex tunes are very inconsistent and not user friendly. If you think it safe to run one, thats fine I know you have a hardon for them since you ran one on your last car and it was perfect. In reality they have been very problematic and 9/10 tuners...

Being a tuner and having my own car turned up to 11 on E85 for the last several weeks, I decided to flash back to the stock tune but keep the stoich set to 9.80 for e85 so I could still run E, but the car's calibration was otherwise completely stock engine and trans. WOW was that eye opening...

Absolutely. Check this out.

I just enable it in the tune.

Their prices are retarded. Huge mistake charging whipple money.

When I do my tunes, I just set all modes to track active exhaust settings - basically all open all the time if that's what my customer asks for. Super easy in the tune.

FYI you dont need pure e85 to get the complete knock protection you get from higher E content. You are not going to see any knock no matter what from anything E60+. You might get false knock from something like headers, but not actual spark knock. Anything e70+ is safe with most e85 tunes you...

If you want to run PCMtec then we can do a real flex tune with sensor - once they support gen4. But on gen3 they do. Everyone else doesnt do them anymore. They are very finicky and rarely work as intended and no you and everyone else isnt watching datalogs to make sure the inferred blend is...

The point is having quite a bit more power on tap for any situation you might want it for. LOL is this a serious question? You also realize you can swap back to 93 once you run the e85 down to E. Then just fill up on 93, and after a few miles flash your 93 tune. You realize that right?

no. And I posted my results of e85 on a stock car weeks ago lol.

We've been doing these like 2 a day. Ive got maybe 50 done now since release. We perfected the ghost cam drivibility and its PERFECT. Even on the auto cars. If you guys have tiktok, I have my page just loaded with pop flame, ghost cam cars and tons of driving videos with my stuff on it so...
