I got a custom made converter in late December, installed it myself and have only run on e85 since. Works great. As I understand it, any car made after 1992 had to be ethanol compatible. So my '99 should be fine. Gas in my area already has up 10% ethanol.
I ran some serious cleaners through my fuel system and crankcase. The guys I talked to say the problem with converting to ethanol is that, it is alcahol, which act as solvent. There is a lot of crap in gasoline, parifins, waxes etc, they get built up in the fuel system. When you start running large amounts of alcahol it breaks up these build ups, and they inturn clog the fuel filter and injectors.
The first converter I got, sucked. It was analog. I got a second converter made that was digital and had flexible parameters that could adapt to different fuel types. In my area it is all e85, 85% ethanol - 15% gasoline. I gather this is the most common ratio. However if I ever can't get any ethanol I can just put 100% gasoline in and it will be fine. It will adapt to the new inital ratio of 50/50 or what ever it will be, and then if I keep filling up with 100% gas it will just stop intervening.
I can adjust the rich/lean, but havn't yet. I'm going to open it up when it gets a little warmer. I'm going to try to lean it out a little.
It gets silightly worse milage, however it has a little more giddy up, which inturn effects the milage. I'm stop and go traffic, I havn't used a tank up on the highway, but I can get 25+ mpg drafting a semi at a reasonable distance at 65mph, and thats on 32" with a 4" lift, not bad. e85 is always 30 cents cheaper than reg87. So I figure its probably a wash, but at least the money stays in the country, probably even stays in the state.
