FiTech EFI system

Ken, thanks for the detailed write up and pics. I've got a FAST EZ EFI and Aeromotive Phantom Stealth fuel pump still in the box that I'll be returning.
I have a question about the wiring: all the EFI mfgs require hot electrical source in both On/Run and Crank positions. When I talked to the FAST tech last month he said just that split second in between is enough to disrupt the ECU. Yesterday when I asked the FiTech tech the same question he said it wasn't going to be an issue. Did you modify your wiring at the ignition switch? If not, do you notice anything happening to the system during starting?

I think the stock ignition switch will work OK - I was worried about the same issue when I did my GM TPI conversion on my Valiant, and the switch generally operates as make-before-break... that is the ignition circuit is made before the power is fully pulled over to the starting circuit. Starting has not been a problem for me using the original 1969 key switch.
