There is only one type of timing advance on the GM (as of v13), which is turned on or off using the 'high speed timing' option. The amount of timing advance is then set using the 'fixed timing' variable.
Not sure if this was answered before...
Am running profile 1 and 2 with a 4.5t
the default is 30 in fixed timing software version is 13.1
Is there any boost enabled ? or does it require the high speed timing option to use that?
