Elmer, so the one that produces correct IAT is the .tun file from post #2...?
Elmer, so the one that produces correct IAT is the .tun file from post #2...?
I asked for his files during the dyno runs we made on Monday. I haven't received them yet. The IAT in post 19 seems reasonable and was going up as I drove. The entire scan was ~5 minutes and the full heat of the engine and the current temperature seemed like a valid reading. Yesterday it was around 80 outside and my IATs were much higher as the sunlight was direct and helping to warm things up in the engine bay. The car had been sitting in the garage after the test drive and the heat had built up. I averaged 166F for the short 1 minute recording. I simply was looking for the IAT change as the previous IAT was averaging 46F. I stopped, put in the e-force tune, immediately started the scan and the temp immediately was different on the IAT up to 166 AVG.
As a sanity check, while set the scantool logging, and wiggle the IAT connector and its wiring, see if the logged IAT is steady.
Well, I am driving the car over bumpy roads during the scan. IF there was a "wire or sensor condition" wouldn't my IAT be spiking high or low as I drive? The temp is rock steady. It's just stupid wrong for my ambient temp. The time I changed the tune yesterday, I was sitting still in the garage. The only wiggle to the engine would be the starter engagement.
If you really want me to wiggle the IAT I will but I can get the IAT to change at will with the tune change in the ECM.
I don't need no steeeenkin sanity check! I'm old! I have a good excuse already!
Lol, ok, I was eliminating any possible extraneous causes.
I pm'd Tech Support, if they see something they will let us know.
Sounds fine to me. When I noticed this, I was totally flummoxed. I didn't have any sane reason why it was doing this. Good luck. If you need more data, I'm available.
Right now, I running the E-Force tune and ignoring my DIC readings.
Later,
Elmer
So just to confirm; you are seeing a difference between flashing two calibrations both with the same OS#?
