using 14.047 for desired AFR and not 14.63?

You would have to leave the Tractor

I saw that you are from Washougal. I like Washougal. I live 45 miles east on the WA side and then up in the mountains.
I think that Chevy366 thinks that I was making fun of Country folk because of the granola head label you get from fox news about the NW. I don't think he knows how many of us country folk there are in or from the NW.
BTW there is a somewhat new tuning outfit in Washougal I have heard some Ok things about.
I run into some of there customers at the races. One guy has a 07 ZO6 that he claims has 630 RWP dynoed by them. Thats around 700 hp+ at the crank on E85. His only improvement are a cold air intake, Headers and a Cam and only E85. LS7 injectors cant handle that not even close. Your earlier post (and link) in this thread exposes the guys that make these types of claims. There is no way the fuel system, pump, injectors especially can support that on E85.
I do not know if it is the tuning shop or the customers as I have heard good things about the shop. We just do not have very many tuners out here in the NW and you could do very well here. Something to consider! Also allot of us hot rod guys out here have Harleys too.
Maybe we could get Chevy366 to move out here too!
Take care in the City,

I can vouch for that...the standard injectors on an LS7 are hitting the wall at 500HP crank on E85.

I worked for Nutter Racing Engines for a few years before moving to Wisconsin. I have friends in Stevenson, Carson, and White Salmon along with Washougal, Camas, Vancouver, and Portland. Back in the early 90's I did a lot of work for a guy with a orange 70 Road Runner and a 76 T-Bird that was in Carson at the time. I think he is in White Salmon now.

I need to do the Math on the Theoretic HP for fuel blends. It is all math so it should be very hard to do a spread sheet. E85 or E100 just simply has more BTU's per volume. End of story.

These are E85 compatible Delphi injectors
They look a little different and some flow a ton.

Cool. Apart from flow rate, it would be interesting to know whether they do actually use different materials to the regular current injectors.

I pulled my gas tank yesterday to check on a possible leak and at the same time, as there has been a lot of E85 through the tank, checked for corrosion effects.

There is bare steel in the tank on the sender bracket. No corrosion. Just normal bare metal. No evidence of any effect in the 8 months running E85 and mixes. The tank should be fine for a long time. Stainless from Rock Valley/DSE.

I think engineers are over engineering the fuel systems for that what if situation. I have ran e85 on my s-10 non flex fuel truck with a 4.3l for over a year had no problems what so ever. Truck is still running it today.

Did you tune it for E85?

[chevy052500hd]

yep did tune the pcm for e85
