Holley Sniper EFI

I finally made some progress on the install this weekend and after a few issues with fuel fittings and the corvetter fuel pressure regulator/filter I managed to get the unit to the point were I have installed the engine parameters and am now in the process of trying to start for the first time. I called it a night tonight after the engine tried to start and a puff of white smoke came out of the unit when the key was returned to the run position, maybe a timing issue?? I'm trying to start the engine with the timing control added. I'll check the timing again tomorrow. I found the instructions weren't very clear and I have had to connect both pink wires, the one from the igniter unit and the one from the main harness.
