Glad to see you making progress! Is this full E85 or a blend? Did you end up with final numbers on pump gas?

This is on E50, and I have not run pump gas since the clutch install.

Is running in the mid 12's for AFR becoming the new norm? I remember when 12 was considered lean and 11's was the norm.

I've tested into the mid 13's, with no indicators the engine didn't like it. Especially when running a dense mix like E50-E60, you can get away with leaner AFR. Plus it gives that little extra injector headroom up top.

Does it look like 390-400whp is possible with 34-35 psi or is that stretching it?

Adam already dyno proved it at that power level at ~36psi. But over 32psi ur in head lifting territory and also the crazy low end torq is a recipe to throw a rod.

correct me if I’m wrong but i believe he also said the turbo wasn’t efficient running that fast to redline.

Yeah your defiently running past the turbos efficiency zone but it was still making power. Turbo technics I think says past 26psi is considered overspinning territory which is nonsense. I was running 35psi.

Thanks to Jason and those who blazed the trail... 300+ WHP after only 3 maps!

Are you seeing any ignition correction on cylinder 1 in these logs? Or any cylinder for that matter? I am still have some sporadic false? knock with cylinder 1 that I have been troubleshooting forever.

Hey Jason I've been running your e50 tune with e60. Should I see a comparable gas mileage to the 93 oct tune (or Better) with the leaner afr's? I noticed the 93 oct tune runs in the 12's as well and I haven't really been able to tell which fuel does better.

I have some plots and feedback from Jason, will PM you in a bit.

This S280 setup is an absolute beast! Really enjoying going for cruises.

The spool is amazing (will check/compare again after winter). 26 psia boost at 3k RPM, 300 Ft-lb torque! Love the sound of the exhaust during logging, or anytime the foot is heavy.

For 93oct, we’re stopping here @ ~27 psi boost up top. I think the HP rollover up top is Timing, and I appreciate Jason’s tune here. This will be my travel map, for when I can’t count on E85 being readily available, so I’m glad we’re not pushing it.

This is Rev1E or 5th, 1st with increased range MAP & TMAP sensors – getting ready for ethanol blend tuning next. Skipped posting as Rev1D it is the same except has the older cals for the MAP and TMAP.

Onto E40!!! Goodbye knock threshold…

I’ll be hitting the dyno in the next week or two. Stock fuel on 93.

Was run 3 in 3rd gear and the first 2 runs were 4th?

Yes, that’s correct.

You can see the difference in the spool up so I guessed you use different gears.

She likes E85 and cold weather...

 

[M-Sport fan]

Yeah, it is a shame that the ambient temps which yield the maximal power, are the same ones which prohibit any traction, even with the stickiest of 'warm' tires.

You said you need AWD now? Go for it!
