I think you mean IAC valve (idle air control valve) which I doubt is broken. This is just a guess but I am guessing tom bypassed the cold air bypass valve and put your little ballcock device in the middle of a hose going from the outlet on the snorkus and the inlet on the throttle body. It sounds like you just made that a straight hose going from the snorkus to the throttle body. That will give you way too much air at idle. The hose from the snorkus should go to the cold air bypass valve and then a hose from the cold air bypass valve should go to the throttle body. The cold air bypass valve is underneath the manifold on the driver's side.

My only issue was with the isis valve. I removed the bypass that Tom and I put on and replaced it with a straight piece of hose. But then the car was idling at 3K. Is my isis valve messed up from the bypass or do I need a check valve in the hose?

Gotcha, makes sense... I didn't pay attention when we took the hoses off. But other than that, the new software is awesome!

Have you fixed your hoses yet?

I've been super busy with work and getting my old tranny packed up and ready to ship. I plan on putting her up on a stand this week to check some things underneith and I'll fix the hoses then.

Does anyone happen to have a picture of the Cold Start valve?


Other than that I love the new chip! My fiance even noticed a difference in the car, lol.

Any more feedback? I'd like to hear impressions from everyone running 2v6?

Michael,
I'll have to install one first

Mike,
I'll be autoXing with the 2v6 software this weekend. Going to be a different course than last time but I'll def. be able to notice any difference. I'll post up some results after Saturday.

So far I really like how the chips work. You can fell a ton of tourque even in 6th up hill.

Just passing through, and I've not waded through half this thread, but to revisit the E85 issue, I think it's noteworthy that Subaru specifies up to 10% ethanol is cool. If anybody cares what the manufacturer thinks, there you go. (Pardon me if this has been mentioned.)

ethanol better be good because I run 10% all the time with the fuel in Jersey. Sometimes it can be up to 15% but mostly 10

This looks good. I spoke with the head of the chem. department who instructs my environmental chem. class at su, he has some concerns about the possible wear on the fuel system, but we didnt have time to go into details.

[TomsSVX]

Thats why I sent several parts to PhastSVX to be tested in a corrosive batch of E-85. Fuel pump, fuel rail, o-rings, etc.... with a dash of water mixed in, we will see what our fuel systems will do with E-85
