Quick question here hopefully it's an easy answer. Can I still use the IAT sensor located in the MAF while also having said MAF failed in the tune in order to run in SD?

Basically, I have the MAF completely removed now and just have the external IAT sensor plugged into the intake tract. However, it seems that the sensor is bad and I have to replace it. But it will take a little bit for it to ship and get here, meanwhile I am left without a working IAT sensor. I'm wondering if I can put the MAF back in temporarily just for the purposes of using its built in IAT sensor but still have the MAF failed in the tune. Or do I have to re-enable the MAF in the tune so I can use the IAT functionality?

I'm going to say yes because I used a ls2 maf on my ls1 car and the car only saw the ls1 iat.The maf and iat even though they are in the same housing are still 2 different sensors.

You can put maf back in to use the IAT if you have the maf failed in the tune you'll still be in SD. To be 100% you can either unpin the signal wore for the maf or zero out the maf table to insure it's not messing with your fueling.

Yeah. I have the LS3 combo sensor. It works fine.
