Hi Guys, After sorting out most of my KR problem i found that somthing else is retading spark. after some help from swingtan i have narrowed it down to pid GM SEMRET. I have managed to log this pid and it seems to be able to remove up to 20 deg of spark leaving me about 3deg at times. The caption says Tourque reduction spark retard. I have tried adjusting,B2502,05,10,11 and 1914 to name a few, to no avail. please if anybody has had this problem, or has any idears i would love to hear from you, the car has not got traction contol fitted to it.and is a auto.
Any help would be great, Thanks Ian
