I installed a Baron Bullet Tachometer on my '06 softail with EFI yesterday. I hooked up voltage and ground, and I attached the signal wire to the Front Cylinder wire on the connector going to the coil.
The tachometer works, but it is only reading 1/2 the rpms it should (idleing at 500 rpm and redlining at 2800ish. cruise is at 1500 instead of 3000)
Does EFI use a single fire coil? Do I need to buy the "converter"? How exactly does it work?
My first thought was to slap a diode on the wire going from the coil to the signal wire for the tach... if I did this with both coil wires, then the tach would see the signal from both cylinders and read the correct rpm, maybe.
