i have a 99 ss 6 speed with nitrous i need to pull timing i had done this with the map/spark advance table on my lt1 car but that table isn't listed for the ls1. Also any ideas on where i would find the table to shut off the skip shift or would i just unplug it and shut off the code that comes up.



Thanks for all the help

 

I don't have the JET software but skipshift should be in the ECM Switch table. On Tunercat it's called C.A.R.S (Computer Aided Ratio Selection) and you just disable it.
