Can IAT be disabled on 1227747

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

The '7747 doesn't use an IAT sensor.

What is the code you're getting exactly?

Both injectors will fire (alternately) as long as the engine is running.

Swap the connectors between the injectors and see if there's any change. It's possible that you have a stuck injector or a bad connection. Are you running the 4.3 bin or is it possible that your bin is setup for a single injector throttle body?

The code I see is 23- IAT Lo.
Concerning the injector, I started with the EBL_F_2002.BIN: from Dynamic EFI. Says its : LB4 4.3l, 5-spd, Fed, '91 1/2 & 3/4 ton truck. I changed the bin to 4 cylinder, but otherwise haven't changed much. I didn't even see a setting to control the number of injectors, but I'm sure I could have over looked it.

I swapped the injector wires but still only get fuel from one side. The Fuel stayed on the left side and didn't follow the wire, so looks like a stuck/bad injector.

Wait, are you using a box stock '7747 or are you using an EBL? There's a huge difference in what each system is capable of using.

I am using an EBL supplied ECU. I figured if it could be done in 1227747, then I could do it in EBL. Sorry for the confusion.
Question is the same, how can I disable the IAT, as I dont have a sensor, nor a wire in my harness to add one.

I haven't used the EBL, but I believe there is a setting that will turn it off. Look under flags.

Why do you want to run without it?
