EZ-EFI only controls fuel, and as was said, any other EFI system can ignore ignition timing if you want. But if the system can control timing I would use it. It's interesting to see the affect that timing has on mid-range torque that most people never knew was there.
next question,i would like using my MSD 7 with one coil,this has a lot of fire power and multiple sparks per cycle, can these systems keep up with it?
I know the FAST XFI has inputs for just about any type of trigger, Crank or distributer. The XFI would then trigger the MSD though a "points" wire output. Now you have your MSD ignition but timing control through XFI.
