PE adjustments on new 9t08nl update

[AJM]

I got my LTFT's and PE dialed in on my truck with the 9r07 revison and I noticed that when I upgraded to the 9t08nl my LTFT was still ok using my setting from when I had revison 9r07 installed but I had to readjust my PE settings because they were off Using my settings from my last revision. I was just curious if this is ok or normal when you update to a newer revision?

I'm new to this but in my logging's for my vette, I've learned that the slightest thing, changes your adjustments. The revision probably didn't change anything to do with your PE adj.

How long has it been since you last logged under that old revision? The outside temp. could be different, gas quality, age and maintenence of the vehicle. I am just guessing.

You can do 3 identical logging runs and get 3 different adj. for the LTFT's and PE's. As long as one finally say's, "no adj. necessary".
This was just my uneducated assumption.

Very true, not an assumption. The tunes probably have less to do with the differences in readings than the environment (temp, humidity, etc)

Alright, I'm learning!
