you can simplify this to a TBI setup, that way you can easily sell this as a conversion kit to EFI, you would need to fabricate a holder that bolts in place of the carburettor and has an injector, a throttle blade, the TPS and the ISCM,
btw what kind of motor are you utilizing to stablize idle speed, and how many pulses are you reading for the crank and how many for the cam and how is your system determining TDC - missing tooth, coinciding pulse?
I was also a part in something similar - made good money from it too.
