Megasquirt looks like a very nice system and I have nothing personally aganst it. But in the back of my mind I just dont want to run a fully custom ecm. I cant help but thinking if something freak happens and the ecm get fried (bad alt, idiot hooks up booster cables wrong, many things could happen) I am now stuck with a jeep I cant drive untill I order a very expensive replacement. If I use a common junkyard sourced ecm/pcm, if something happens I could go into most any parts store or junkyard and get a replacement, I can also buy and keep a couple of spares.

Looking on tunerpro at nothing but the dowload page, I saw a couple V6 ecm's that are supported. (but didnt dl and look at the definations) Plus I dont know much about these engines either.
