I used to be able to reproduce it every time, now I always fail at doing that like 1 in 20. Like once in a week of driving, and only tiny as well.

You mean you could always reproduce it when on 98? Or when you first started using E85?

Yeap, 98.

Your log should tell you this, provided you have selected it as a parameter to log.

I don't think anyone is running ethanol to save money. The mileage is not as good, so fuel costs end up comparable anyway. The whole point for people like us is power, although some would do it for the perceived drivability improvements.

I just went back last night, and gas price was one of many factors for me. 27mpg/93 vs 21mpg/E85 and here E85 cost more right now than 93. Add to that, that only 1 station that's out of my way has it, as winter is setting in cold starts are getting to be a pain in the rear, and I have a long trip coming up that I don't want to fill up my trunk with gas cans of E85 or map out places to fill up along the way. I just have to wait a few days for my computer to relearn before I can test the performance difference, and feel.

Over here it is a lot cheaper so I gain financially (medium term). I love the added driveability and power is nice but far from my main objective.

Also as far fetched it may seem to a (US?) car forum, I actually care that it reduces my carbon footprint a little bit and provides some form of alternative (far from the best but still). Owning a car is my biggest impact, otherwise I live in a small house with geothermal heating, bike shortish distances quite a lot, eat mostly vegetarian and avoid unecessary flights. As for satisfying my driving hobby, this car combo has a very high fun to impact ratio, and suprisingly practical/usable to boot

Please no flaming, not judging anyone here, just want to show what a wide public this car has

I have trouble wrapping my brain around 93 being less expensive than ethanol. I suppose I should check locally what with the price of gasoline dropping and all.

I knew the car is pretty well global in popularity, but I made the narrow minded mistake of thinking locally. Ethanol is a pain in the butt between getting it and redoing maps to make it usable, at least around here. It's hard to imagine doing it for anything other than an increase in driving pleasure.

It wasn't always cheaper. It used to cost about $3.05/per gallon while 93 was $3.50 per gallon, which still works out to cost more per mile. But right now according to these online sources:
http://www.altfuelprices.com/station...Warner-Robins/

E85 is sitting at $3.25 per gallon

http://www.georgiagasprices.com/inde...s&dl=Y&intro=Y

93 can be as low as $2.95 per gallon

Others have pointed out that they can get E85 for $2.50/gallon and If I could get that price I would just adjust my tune for cold starts, buy some 5gal tanks, and stick with E85. But right now with it being about 22% less mpg, and 9% more expensive, It adds up to about $12 more per tank. (assuming my math isn't screwy).

also without wanting to flame, I think it's been proven that the manufacture of E85 produces more carbon than it's use saves.

Yeah was about same cost per mile but now tempting. I ran on empty light for about forty miles and finally broke down and had to pump 93 since no one had ethanol

After driving for a few days with the edited Crank Pulse Width tables, I can say that it was a definite improvement. After editing, every time I started the car cold, it took two attempts. Didn't matter if it was 40 or 60 degrees out. It was like the system needed to be primed or something. It beat the heck out of the half dozen or so it used to take.
I've since gone back to 93 because I got tired of being late for dinner at least once a week because of the lousy availability.

I wish I could get RR working again because I am down to click click vroom on ever start down to 30 degrees (the lowest it has been this season). If I remember correctly from last winter, I have never needed more than two tries to fire up the car down to I believe as low as -10F.
