IM new to all this tunning stuff just got the efi live the other day with a wideband set up and now i need osme basic tunning info to get my car back to normal because its a 2002 ls1 and tranny in a 1986 iroc.. need some codes taken care of and to clean up shifting. I figured the easiest way is to get the computer back to normal operating then log a bunch then see what i can do after ?? if anyone has time to help a newb please do this is alot of info to soak up thanks.

hey bif - scan your DTC's, then type the code in the navigator bar and hit search. should take you right were you need to be to do what you want.
