adjustable setting problems

[justinesky]

Hi!
My problem is when i try to adjust my settings under adjustable setting it does seem to take. It i try to change my timing or P.E. or anything it just goes back to 0 after i click save. it use to show what everything was set at like my ltft were st to -6 and my P.E was at -3 and so on. NOw everything is at 0. I updated my intune today but it didnt help. My TCM (trans tune) Is working normal. I can make adjustments in that. I also made changes to my ECM 2 weeks ago and all was normal so I am not sure what changed. Any ideas?

My car is a 2008 escalade 6.2L

THanks,
Justin
