Working on tuning my first l83 with the E92 PCM. I had a couple questions before i start.

1. Is there a limited to the number of PID's you can log? the LS1 pcms was always suggested a max of 24.

2. To correct the VVE tables, do you run the same basic procedure as a calc.maft or a autove, as I haven't found much for write ups on how to correct the VVE, just explaining how the VVE works.

3. I am seeing knock when i initially punch it from a stop, i assume this is burst knock and i can zero out all those tables like when tuning an ls?

4. Do these DI motors like running at a higher temp? I assume its for emissions, but i noticed how hot it was running then in the tune it's "ideal" temp is 221. Will i loose fuel mileage turning the fans on sooner and running it around 190 to 200?
