IATs pull timing. The whole intake tract heat soaks, especially when you're stopped. I've been wanting to experiment with some well placed louvers to aid with heat extraction but I haven't got around to it.Could it be related to the reduced intake air density of hot air? Maybe a reduction in ignition timing due to hot air bringing on ping/knock?
The green connector fits perfectly after grinding off the tabs although I have a stash of all 3 these days. The yard I frequent butchers harnesses anyway. I bought 4 of the Green/Blue P59 PCMs with IAC drivers and analog a/c input with the connectors yesterday for $35 each. 2 came out of 2003-2005 DBC Express vans and 2 came out of DBC 2003 Tahoes. The 2003 4.3 van one I bought is getting swapped into my buddies S10 Blazer with a turbo 4.3. I have a 350 that is going to run with one. More than half the trucks there had 0411s including a couple 01-02 van ones that already had the right pcm file to run L31s. Yard probably had 100 LS PCMs.I'm all in on the 0411 swap. I ordered one on ebay loaded with the 01 van vin that Supercharged posted in the base tune thread. I also got a red and blue connector set coming from ebay. Today I bought another connector pair and an obd2 port at a local yard to make a bench tuning harness, like this yt video:

Wrecking yards won't cut up a complete harness, so I had to find a damaged one to get just the connectors. I could only get blue and green connectors. I hope the only difference is the position of the guide ribs on the colored plastic. If so I will grind the ribs off the green one and just hope it's willing to self-identify as a red..
