IAT Sensor I have installed a LS6 into a Cobra replica. I am using the stock PCM and wiring loom.
The only wires I can't find a home for, are for the IAT (intake air temperature) sensor. Do I need to run one, and what effect does it have on the engine. Can I just by-pass it?

IAT Sensor I have been told it is possible to bypass the sensor using a resistor. I know someone who has run his engine without it, so it would be really useful to try and understand what it is doing exactly.
Does anyone know where I can buy the sensor from?

I should have said I am using a mechanical throttle (LS1) on my LS6. I think this may be why I can't find a home for the IAT sensor. What do you think?

I think I am going to fit an IAT sensor in the air intake tube. Does anyone have a good source for GM parts, as I will need to get it shipped to the UK, and I don't think this is a part that I can source over here.

My Camaro was running like garbage, it was braking up (spark knock). I scanned it no codes, just for fun I unplugged the IAT it started to run smoother. I drove it for 3 days like that it ran alot better, Then I got a check engine light. I put a resister on and cleared the code. What I dont understand is when you put the resister is it adds timing, but for some reason if pretty much eliminated my spark knock!? I know it wasnt bad gas cuz Ive been running 93 with octane boost.

No I haven't had a chance . I'll try and investigate further over the weekend. At the moment I am thinking that the resistor will be the simplest solution.
