Megasquirt fuel injection

I have ordered a megasquirt kit and will experiment around with this fuel injection controller this winter. I plan to test it with a gm TBI unit on my 258. If I can get it to run well I will shared the code with all. I plan to use as much gm and univeral replacement parts as possible to keep the cost down and make duplicating the sucess as easy as possible. Would like to see a homebrewed TBI for under $500.00.

Re: Megasquirt fuel injection

I'd be interested. How much is the Megasquirt system?

Re: Megasquirt fuel injection

well my homebrew (aka ghetto) tbi was going along pretty cheap, but for some reason (oh yeah my stupid carb blew up) i had to expedite things and broke down and called howell. so basically i paid $100 for a really nice TBI unit and ECM and howell is charging $620 for the rest (entire kit minus tbi and ecm). so i still come out at $720 for the entire thing and all howell stuff except for the tbi and ecm, guess i cant complain, at least ill be able to get my jeep running again.

what the heck is a megasquirt?

Re: Megasquirt fuel injection

whoa, needed some coffee before that

nice concept though, seems like it would eliminate alot of the "complication" of the tbi conversion not having to deal with ignition stuff and stick strictly with just fuel/air, essentially like a computer controlled carb, but with the benefits of fi, hmmm

Re: Megasquirt fuel injection

I emailed a guy in Russia that installed a TBI unit on his 258 CJ using megasquirt and he says it runs great. Sent me pictures and all. I hope to get the ecu kit some time this month. I'll start gathering the other hard parts before snow hits the ground. I will use a new fuel pump of course, and the custom efi site has info on stock pumps that will work well for a gm tbi. I want to avoid using anything oddball, other than the homemade ecu, that way it will be easy to get replacement sensors, etc. I'm lucky to now have a heated garage to work in this winter, so I can do some jeep projects as work slows down and winter sets it. Worst case scenario, if it doesnt run on Sunday night, I can slap the MC2100 carb back on and drive it for the work week.

Re: Megasquirt fuel injection

I'm on the current list to get a MS, and I am plan on having it operate a 4.0 intake manifold on my 84 CJ-7. I'll definately keep the board advised with my progress and my experiences. A local friend of mine is buying one for his 304 as well.
