Hello Everyone in the group,=0D

I am in the process of retrofitting a 1988 vintage 318 with=0D
Throttle Body Injection into a Bombardier Tracked=0D
vehicle called a " Muskeg ". We have been using this vehicle to log with=0D
and up till now had been using a Holley 2bbl=0D

happens, the float sticks and the vehicle stalls.=0D

With all of the recent discussion on Mopars, and with the ECU=
=0D
internals I was hoping that you folks might=0D
be able to point me to where I can find info on the SCI interface /=0D
protocol etc that would let one retrieve codes etc from the=0D

I am aware that I can using the ' flashing light ' method an=

I have saved this part of the wiring harness to use=0D
for that purpose. But having a hobby in MicroControllers and such, I woul=

if I can. Up till joining this group, I have not been able to find much =
