i recieved one car yesterday for tuning, the car has an ls1 block (sync sensor in the backside) and a 60-2 ref trigger. Sync sproct is 2 signal. How can i set the trigger for this engine?
Are you sure you have 2 teeth on the cam? The early LS1 should have the "24X" pattern, this is 24 teeth on crank and a half moon on the cam, this is ref/sync mode 23. The later ones (2006+) should use "58X" pattern which is 60-2 on crank and 4 teeth on the cam, this is ref/sync mode 17.
Yes it has 2 teeth on the cam but the crank shaft was changed into ls2 crank shaft with the trigger of 60-2
