I'm using a 1227747 to run an old Pontiac Iron Duke, 4 cylinder. The car didnt originally have an IAT input to the ECU. Also the new wiring harness I bought for the 1227747 didn't have a wire for an IAT either. So....is there a way to tune it out with TunerPro? It looks like I am getting a CODE23 (LOW TEMP WARNING)


Also another question this project. I am using a dual TBI setup from a 4.3 Chevy S10 Blazer. Only 1 of the injectors is firing. Is this to be expected, since I am just idling in the driveway, and the 2nd injector will kick in when the ECU senses the engine is under load?? Or do have another issue? Bad injector?? Something not right on my tune setup??

Thanks
