New 4150 style Sniper EFI

Edelbrock EFI uses mostly GM sensors and a Magnetti-Marelli controller, same as Fiat/Chrysler. That stuff has a pretty good track record nowadays if you dont look too closely at M-M's past history. Sort of the Lucas of Italy.

Yes, most all of these systems utilize OEM sensors. Edelbrock looks like the most promising unit, as the ECU is remote mounted, no different than the Terminator kit from Holley. I haven't looked into it, but from what I've heard you cannot data log on the Edelbrock, is that correct?
