FiTech EFI system

Not trying to start anything as I am not an expert but, Just to add to the above, You can retain an aftermarket ignition box to fire your engine, even if you want Fitech to control how much timing you use. Their instructions show both without, as Johnny explained, or with an MSD or other ignition box.

For me, I already had my system set up with an MSD 6AL and high Quality Coil, so I am using Fitech to control my timing, but have retained my MSD 6AL box for multi spark etc. I use a locked Mopar performance Distributor.

Should the MSD box fail at some point, I will use the Fitech for everything.
