I may try a spark only to get my feet wet with prom burning.- And get the wiring sorted..
I'd prefer to not buy 2 different ecms. Learn 2 codes and wire the car twice.
So the 730 & s_aujp.

Can this be done?

I looked through the 7747 spark.txt and bin. I didn't see anything that obviously turned off the fuel. But that was the first time I looked at that code hac & bin.

Do you need to do anything with the fuel code?

Is a resistor or something required on the injector circuit?

 

Should work. Can't think of any reason why not. For fueling just need to turn off the O2 DTC's for the SES light. No code changes were mode for the 747 spark only.
