Hey,
Yea you can set-up megasquirt to trigger an alcohol/water injection set-up. My megasquirt is running fine, but i havn't really done to much with it. The power inlet on my girlfriends laptop got messed up so it wouldn't take a charge, so i only had about a week to play around with it, and now that we have the laptop back my jeep sits at my parents house, where i've been wanting to work on it but since school has ended i've been busy with the holidays, i'll be out of town again this weekend lol.. I have it running fine right now, i leaned out the cruise to about 16:1 AFR, and WOT to about 12-13:1 (didn't get much of a chance to datalog and adjust the WOT settings). I am goign to be doing EDIS ignition also, havn't decided if it will be before or after I turbocharge the jeep. For the price i think megasquirt is great, I built mine myself and i had only limited soldering experience. The instructions are REALLY good.
Where do you live? i'm assuming in florida somewhere? I live around Orlando.
