Well I talked to a few people running the mefi ECU and they all said it was weird to program and the same price as the FAST to get everything hooked up the way I wanted. They are rock soild reliable. I also found out I can hook up the FAST ECU directly to a RACEPAK unit with a 375.00 adapter. I'm trying to make this as easy as possible and cheap so I don't have have double sensors on the engine for each item. RACEPAK makes a connector for most major ECU's. The cost of the MEFI and the FAST are about the same once you get everything you physically need. Plus I cannot find out if the MEFI could ever run a Kinsler crossram, and if it could who in the world would have a base tune for a MEFI with a Crossram. I also found out that MSD sold the MEFI system to Painless Performance and I prefer not to deal with them.

Not sure if that is useful info, or just BLAH, BLAH, BLAH.

But I'm now installing the FAST and hooking it directly to the RACEPAK with an LS7 and someday and Kinsler crossram.
