2016 Camaro SS Cammed. Some sort of timing limiter

There is some sort of timing issue going on. Stage 3 cam, Hi-Ram Intake, E85, Long tubes exhaust and CAI. It's a stick car. When you go to take off it seems sluggish as heck sometimes. It will then all of a sudden come to life. The timing is dropping to around 5 degrees and then shoot up where it is supposed to. There's no timing retard going on . I'm absolutely lost. I will post tune and datalog of it happening. You can see it in the last 15 seconds in the log and several times during the test drive. :banghead:Attachment 91190Attachment 91191

torque model is wrong and/or VVE is not tuned

Is this corrected in the Virtual Torque Tables? How do I set up a PID and histograms to set that up properly? Where do I source the torque to enter into those tables?

Are you logging immediate torque source?

Yes and it is Torque Management Advance is taking all of the timing out of it until about 3,000 rpm. Does it in 1st and 2nd gear mainly. Is that the virtual torque tables?

You probably need to tune your VVE before you worry about your VTT

since the original post I've gone through and tuned the VVE and tuned the MAF as well. Still does the same thing but only in 1st gear.

if your traction is not completely off that could also pull ignition

I agree but this is just a minor takeoff. Literally just letting out the clutch and gas at about 25-30% throttle it pulls Tq Mgt Adv at about 20*ish of timing to where the car is trying to accelerate on 5 to 8* of timing. Then BOOM at about 50% throttle it disappears. I looked through everything in the tune and I still can't find anything indicative of this action.

Log Immediate torque source.
