A buddy of mine has a H/C/I 2SS Camaro that we've worked hard on to get the best drivability possible. It has the GPI stage 1 NA cam and the comp cam limiter in the VVT phaser.
I've noticed for a while that in first gear it pulls a bunch of timing when going WOT. I've tried several different things to fix it.
The knock detection is telling me that that there are events in cylinder 1 and sometimes 2. It only does this in first gear, and traction/stability are off. I logged the cam position and the KR does tend to correspond to the cam moving from the lock pin position. Has anyone seen this and if so found a solution?
Car has 100 Octane in it.
