I've got the ECU setup for it already. I'm using huge BigShot solenoids from my previous 4150 plate system, so progressive at such a small shot probably wouldn't work well at the tiny duty cycle. I'm going to try it off the EFI fuel system as a wet-shot since I'm running a 255LPH pump on an otherwise small engine, and I don't think the injectors have enough capacity to provide the extra fuel. 1 switched input to arm it and the rest is ecu controlled to 85% and 4000 rpm to activate. Progressive and delay are just programmed inputs. I have a low pressure pump and standalone cell (also from the plate system) for the fuel if it needs more. I got rid of the megasquirt because it was TOO adjustable and opensource. I needed better baseline.
