High IATs killing my VE table. So today it was hotter than Satans ******* and I did some VE tuning. Stopping every few miles flashing and going on. We’ll I noticed my IATs were over 100 all day and after idling a few minutes they’d be 150 ish. I had the majority of the VE table within 3 percent so later tonight after everything had cooled down I drive the car and I’m now 15 percent rich. We’ll after I let the car idle trying to figure out what happened I take it for a drive and everything fell back into line. What’s causing this? If it’s hot outside (high IATs) I’m getting mid 14s and under 5 percent if it’s cool out I’m running low 13s. It’s a open loop speed density set up 02 Fbody. Thanks.
I had to relocate my IAT for this same reason. Mine would read 130*F idling when it was only 80* outside.
The computer is leaning the mixture because it thinks its getting 150* air. You then add fuel and it makes it rich after the IAT comes down.
