You will have to contact them to find a distributor.

Two ideas I had were liquid injection and gas injection.

I've seen three types.

Even if you researched the VW MAF signal, and built the circuit to adapt it to the MS input, I don't think you'd want to for this application.

These are typical DC voltage Thu, 11 Jun 2009 12:34:55 GMT rpborthw http://autos.groups.yahoo.com/group/megasquirtnspark/message/3952 http://autos.groups.yahoo.com/group/megasquirtnspark/message/3952 Steve is correct on this. Not just in tractor pulling but in Diesel engine research and development there is work being done examining the premixing of fuels Thu, 11 Jun 2009 12:17:55 GMT Marco Fischer http://autos.groups.yahoo.com/group/megasquirtnspark/message/3951 http://autos.groups.yahoo.com/group/megasquirtnspark/message/3951 By the way:   Ever heard of E95 fuel? In Sweden the public transit busses, which have stock Diesel-engines, run this fuel. It's 95% ethanol and 5% additives.

I suppose you want to use it on your diesel for the same reason.

Indy cars, Alcohol Funny cars, Super Modifieds, etc...
