Gains from E85 (ethanol) on an N/A bolt on 370Z

ANMVQ

With the VVEL/VTC system on this motor, do yourself a favor and find a competent tuner with a reliable dyno. I've seen minor 2-3* changes to VVEL net 4-5tq through parts of the curve, or the opposite -- cause huge 40tq dips in the curve. The goal is to fatten the area under the curve, and you're going to have a hard time trying to get 4tq here and there (and the cumulative effect is nice).[/QUOTE]

Yea finding a local tuner is a 0 to NO shoot for me Mass has NO ONE.

My dyno and TW curve is flat

That's good, however that graph has no context for me -- looks like some sort of base and then a "tuned" pull -- looks very similar to the last G37 I did on UpRev.

My point was I can post overlays of 5 pulls for you and show you how little changes in the VVEL made minute gains between pulls but the cumulative effect was greater than the starting point -- you don't have that kind of precision and repeatable doing a street tune.

In an case, I'm not going to argue the merits of street tune (etune) vs dyno tune. They both have their niche.

no agreed about the Street vs dyno thoughts, I should have been more clear about the graph. The lower WHP line was my finished UPREV tune and the other "Higher" line was my finished ECUTEK tune. I pick up 15 WHP just swtich from UPREV.

We made 10 pulls total, 5 on each software

That makes sense. The lower graph really looked like the motor wanted more timing. That's been one of the most frustrating things of dealing with UpRev -- you can tell the motor wants one thing, and no matter how hard you faceroll on your laptop, the ECU would fight you the whole way.
