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

njobe89

which injectors do you recommend?

do i need to switch from uprev to ecutek for the tune or is staying with uprev fine?

i know ecutek offers launch and few more things, but i don't need that

Whatever your tuner is comfortable with.

You'll make more power on pump just switching to ECUTek. With the timing control being garbage on UpRev you probably will only seem the initial gains from the fuel itself. On top of which you can't really do a true E85 tune without screwing up the load scaling on UpRev IIRC (been a while since I looked).

Thanks for posting Vit. Also saw this on your blog. Wish you were down here in AZ so you could mess with my tune! You've tuned like 4 of my friends k20s hah!

I should be visiting Phoenix sometime soon, Andrew should be wrapping up his turbo K20 MR2 sometime soon -- we'll see if we can get 900whp+ out of it this go round!

My friend was telling me to take a road trip to OR for a retune from you lmao. I've asked about sending logs but it is a little more difficult platform it seems like to etune. Nice! Sounds awesome.

Yeah if you really want to get all you can out of it you have to sit down and dial in the VVEL. The Honda stuff is relatively simple in comparison to the VVEL system on these motors -- and you're better off using ECUTek on the 3.7 motors at this point.

I used GTR's.

What timing are you running? My tuner cant get over 28 on any of the cars. He can tell it to but it wont. Im stuck at 28 on both 93 and e85. E85 lost me around 15hp. It just cant burn the mix soon enough. Is this what you're seeing or talking about with uprev?
