Quote: You can't use a distributor. The EFI needs to know where #1 is.
Regular MSD crank trigger doesn't work either because the EFI watches for 28 (can't remember the GM reluctor wheel count?) pulses per rev.
Ati and innovators west (i believe) can make you a balancer with all that built in. And you use the distributor for that cam sync but cutting off 7 reluctors and using the one left to dictate #1
