Your ignition timing is going crazy as well. At first i thought it might be a misfire.

Ignition swing at idle is due to a cam swap of some size. its a little choppy.

Ignition swing at idle is your adaptive idle control at work.

Are there any more TCC pids available? It looks like the converter unlocking and locking again.

1) trans is either just barely trying to downshift, a clutch pack is trying to slip, or as stated the convertor is unlocking for a split second.

2014 zf8, you need to do another read of both pcm and the trans

2) NO - 75 kpa at idle, 100 kpa at cruise is way wong

Ok this is the information I was looking for. Call it bias but I felt it had something to do with the converter possibly. Side note, If i read again, I have to license the trans separately correct?

Excellent information or confirmation into what i thought might have been wrong...wong. The map calibration data seems to be correct and they swear the map and injectors are stock. I have my doubts.

Looks like we're on the right path...at least I hope so
