Quick Update:
Very productive weekend so far. Just got logging/viewing access to all the CAN channels necessary for v4 tuning logic:
-Actual dbw throttle
-Oil temp
-DME boost target
-DME actual boost before throttle blade
-Air intake temp
The CAN logic is a bit different from that of the n54 so this job was harder than expected. The scaling is also different on many of the channels which came as a surprise. But so far, I'd say we are 80% of the way to have a fully functional v4 tune for the n55. With autotuning to follow a few weeks after (firmware update only).
