So, as an update... I'm having trouble getting the vanes to open and close how I want them at idle (open for Temp 1, gradually more closed for Temp 2/3, same for Temp 4 as it's rarely called up). Can't quite figure out the VGT learning/temperature/allowed difference logic, without potentially messing up the driving portions of the tables. It's really challenging to figure out which parameters the truck prioritizes. The other thing I found strange is that there's more EBP at a warm idle with the vanes "open" than at a cold idle during which there is a couple psi of boost.
Attempted to strength exhaust brake torque tables. Still undecided if that made a noticeable difference. Probably have to start closing the vanes more at a 0 load in order to really see this difference. Was hoping the computer would take over there.
Dropped the shift points for 1-2 up shift by 6 or 7 mph. Happy with this, as it doesn't feel so jerky and tow-haul-like. Much better for icy roads. Much less of a waste gate release too, as it no longer builds >10 psi boost in such a short time.
I understand the relationships involved with timing calculations, however I'm unable to get Excel to use the IF arguments required to behave like the ECM at this point. Ran out of patience on this, so hopefully torquebeast pulls through for us. From what I gather, it actually seems like the timing at cruising is really conservative on the H&S tunes... But I can't back this up with concrete figures, so take this with a grain of sale, as I'm not claiming to be an expert.
Definitely open to questions/concerns/comments! Sorry for the rambling post fellas.
