Local Pittsburgh meet part deux
didn't really see that much of an improvement using lean burn while DD - I played around with a lot of settings etc and would see a 1-2mpg improvement here and there but it wasn't always repetitive......staying out of boost as much as possible is the best way to save fuel (what fun is that?), or leave the evo at home and get another car.
Best highway I ever had on e85 was 19.8 mpg and that was on the stock narrow-band sensor....it was purely highway on a trip staying out of boost pretty much the whole way -just cruising.
You can use the AEM wideband to control your part throttle fueling, it takes over the stock sensor......did it with my LC-1 and ZT2, but never had the best results vs. the stock sensor due to the sensor being further down the exhaust stream as Ian mentioned. I had plans to move the wideband sensor up closer to the stock sensor but my time with the evo ran up.
One thing you can do also is mess with ignition timing in the cruising areas of the map, I saw some nice drive-ability results doing that on e85, most only worry about WOT but a lot of improvements can be made on cruising with enough time spent. Same with 93 octane......just need to spend the time.

Haven't gotten it done yet. Just ordered the tires and hope to have the wheels here shortly. That way we the wheel/tire combo to make sure it's done enough. I'm having Ryan Moore do mine.
this is true! what i was thinking is IF i was to tweak the map around cruise i would have to run in open loop the whole time. then id have to tune the whole map, making it more trouble then its worth. thats why i was saying i wish i could simulate the o2... i guess its possible... but still more trouble then its worth
ill keep this in mind. yeah the fuel economy is just a consideration if i switch. I dont DD the car so that is really the only reason i would even be able to do this. Basically it would be driving to and from races (beaverun is about 100m both ways) and the e85 pump is 10 miles from my house off the turnpike i take. I can probably work this out if i feel like it. Im really curious about this, its interesting

I had Ryan roll mine. He did a good job but got a little over zealous on the passenger quarter and creased it. Just a heads up.
Ryan Moore has done plenty of cars, and is the one I'd let do mine if I didn't do it myself. 
the evo has a bolt near the rear that usually causes the problem. I would never do this to someones car without them knowing that these things happen.
Jer and I both run the a6 285 30 18 and it makes me sick that they cost that much new and wouldn't last me a season.

well between the two clubs (SCCA & NHSCC) there are approximately 20 events (+/- 2 or so)....
you get an average of 4 runs per event (usually 3 for the SCCA and 4 or 5 for NHSCC depending on turn out)
so in a season you have roughly 80 autocross runs.
80 / 2 sets of tires = 40.
you should get around roughly 40 (again +/- say 10 depending on variables like driving style, surface, car prep, etc...). for example Beaver Run tends to be much more slick than North Park, so you probably won't lose quite as much tire at BR as NP.
just rough guesses, but then maybe throw in a Wilson Circuit event, and a Time Trial or two, and you're looking at quite a bit of money spent on rubber over the course of the summer.

not a bad estimate though.
Whats a decent tire for track/autocross and then DD also?? Have all seasons on the car now, my stock advan tires were worn down to the metal strips! Of course i dont want to spend $1200 for tires and they will be gone over the summer/fall!
