I've had my car code for awhile now and have issues using device controls like TDCO takes awhile to get setting I want.

I'm running a gear set instead of timing chain and find that the gear manufacture (DSG) states timing on 1996 and newer 6.5's should be between -1.70 & -1.90 while 1994 & 1995 6.5's only -1.95 is recommended.

Anyway, with all the features the Car Code now has for resetting I wonder where to learn how to use it correctly?
