LAN, would it be safe to say that the stage 2v7f (obviously with MAF and injectors) would outperform stock even while using E85 fuel instead of 91?

I suspect so but don't have any data on it. Unfortunately e85 is not available ANYWHERE around here. Phastsvx is the only person I know of running it in an SVX so I would ask him. The feedback I've received from him was good.
The vanagon guys haven't given me any performance feedback. They are just happy to be able to distil, drive on, and drink their own ethanol. |

So these roms will NOT work with a 96+?

I'm not quite sure what you meant to ask. AFR and lambda are the same thing expressed differently. AFR is the expression of the ratio of fuel to air. Lambda is the expression of afr as a ratio of the stoichiometric ratio of whatever fuel you are using.
In 2v7F runs approximately the same ignition timing for e85 as it does for gasoline. It's quite possible there are gains to be made by optimizing the ignition advance specifically for e85 but I don't have the fuel to work with. I can build you a high compression engine for $6500. Quote:

I would totally take you up on that engine to test out the possible benefits of E85, if I had the coin! Is there any way to bump compression on the cheap?

Ya, that doesn't really make much sense to me. Anyway, just fyi when you get into running an alcohol rich fuel like e85 afr/lambda becomes much less important than it is with gasoline. With gasoline if you go too rich you loose power. With alcohol if you go too rich you just don't get much more power. The only reason not to run rich with alcohol is it's a waste of fuel. For racing purposes you generally tune much like with diesel--throw in extra fuel just for the **** of it and don't wory about it. This is a result of the much larger spread between lbt and rbt. That would be more fruitful reading for you.

I generally run my wideband in a lambda reading all the time. I would prefer 40 points of usable feedback rather than the 20 or so Air to fuel mode will display on the readout.
I must admit I have not run it in a year. When testing , we were still in the testing phase of the software and had not made the jump to the injectors. My impressions where the low end had a noticable amount of tq. Also, while running the fuel i could grab the intake manifold and hold onto it. Gotta love the combustions temp of alcohol. Ask me again how it runs on the new turbo with injectors, fuel pump and software in august. By then we should have some drunk-fueled track numbers.

Is it possible to run 2v7f with larger injectors?
Preferably 500cc+ injectors. Dustin

Stage 2v7 was made for 370cc injectors so I would not think you could use any others with it.

Re: ECUtune Stage 2v7 & Stage 2v7F
just received a chip and installed it but , : Clear memory using Subaru select monitor ... Whats that ? Is that the same thing as to clear the engine codes ?

Re: ECUtune Stage 2v7 & Stage 2v7F
Hey Normand,
You don't REALLY have to worry about that. A select monitor is the factory licensed diagnostic and communication tool for communicating with the ECU. Clearing the memory with the select monitor makes it easier for the ECU to learn the correct ignition advance correction to match the new software but even without it, given enough time, the ECU will learn the correct values. |

Re: ECUtune Stage 2v7 & Stage 2v7F
No but i may be releasing software for dual intakes with two svx maf meters and sti yellow top injectors.

Re: ECUtune Stage 2v7 & Stage 2v7F
Thanx a lot , ill let it lear then !! I'm very satisfied with all that i've purchase so far ( and it's not the end .. ) with ECU tune . I've just changed a wheel bearing , they asked me 4.5 hour of time . I know that it takes a bout 2 hours ... If you had a garage near my home , maybe i'll move for that !
