I'd be surprised if anyone is up-to-speed on deleting all teh stuff you need to disable in a 2005 4.7 ECM (trans, evap system, anti-theft, speed limiter, ABS/throttle overrides, cruise control, and some of the OBD stuff).

Even if so, it's gonna cost as much as a MS-II and you'll spend more effort to hack the OEM harness as if you made/bought a new one for the MS.




There are only two real downsides to using the megasquirt or any other aftermarket EFI controller in this application. One is the transmission. If you want to use the dakota transmission, the megasquirt can not control it so you would need to either run a different trans unless someone makes an independant trans controller for it. Second is the tuning. The factory efi computer will run the engine smooth as glass and will require you to put no thought or time into that aspect of the conversion. Did you try contacting that hemi fever guy?
