Ford vs Chevy Build-up

Rich looks like you created some of your own problems should be easy to fix with some time. I believe you o2 sensors are daisy chained together in the wiring so if one is not plugged in the other one will not work. Some of the years of cars are wired differently on this circuit. if you are missing the engine coolant sensor you will have problems, your after start enrichment table is like a choke will not change your fuel going to the motor as it warms up. Have not used the system you are working with just the stock computer with a chip. hope this helps. good luck
