FiTech EFI system

if you're looking to push the timing control to the peak... these (assuming SB)

or...lock out a stock unit, or i believe some have opted for a parts store lean burn unit, which come fully locked.

in theory....if your engine's initial timing is over 15 degrees, and the unit throws full cruise advance at your engine, it can spark jump. (without rotor phasing) we have never seen or heard of this happening. and if it did, youd simply bump down your max timing at cruise a few degrees.

pm me or contact me below if i can help further!

Well I started without the timing control running fuel only and the factory electronic ignition that ran great with the carb but the fitech only ran maybe 4 times for 50 cranks. When it runs it runs well and will idle forever, but once I shut it off and try to start it again it'll never run. It fires but immediately stalls. Completely fed up with this I swapped in a lean burn distributor and tried to let the fitech control timing but once the lean burn is plugged in there is no spark. And occasionally the handheld says 615rpm annd the injectors fire like its running but the engine is not.
