Ls3 slot syle on e40 (possibly other OSes).. Found an issue.

Woo hoo! I happened to take a peak at the file size of the beta file, it appears we have a new beta available.. E38 IAT cals for everyone.. Sorry if I gave away the surprise, what a nice treat to come home to. Thanks guys!

On the frowny side of things, the 2008 Corvette M6 IAT cal is the exact same thing (scale and everything) as the E67 2008 Hummer H3 that we have been able to read for some time.

What REALLY throws me off is the IAT2 table for the 08 Vette has a different scale with the same values!

Update: Looking at the values, there are more than a few that match up against the stock Delco cal on my 06 E40 TBSS.. 12261, 1806, 334, 133, and finally, 78 (ohms).. The resis and the corresponding temp are the same. Perhaps this was a backup cal for the PCM in case it was fitted to a car that used the Delco cal? Whatever the case may be, I'm 99% sure thats not the slot cal I've been looking for.. I'm going to stick with the IAT 1. duhh .. Just thought I'd mention that to clear things up.

I still cant get my LS3 style mafs IAT to read right on my E40, as the scales are not linear, or the same scales from the E67 compare file to the E40! Any ideas to get this to work right? I have a feeling the 2006 trailblazer 4.2L IAT would be the same scale we need in the E40, it still uses the old P12 which was similar architecture to the E40.

Did you change the headers too? You can't just change the values as they are based on a different scale.

I've had better luck just opening an LS3 file and an E40 file separately when doing this instead of trying to use compare. Have you tried using the values from IAT 1 and IAT 2 just as a test?

How do you know they're wrong?

I put LS2 IAT1, LS3 IAT1 and ZR1 IAT2 all on top of each other on one graph

The first one goes down to 40C (104F)

Then I did one graph that goes down to 15C since I figured that's the lowest most people really see in normal operation after cold starts. I guess in some climates you'd see lower

The next one goes down to 0C

Then last one uses the full IAT tables.
