LCD Gauge Update #3: 35 Data Items on 16 Pages!

Small update:
Wouldn't it be nice to have a "VVEL Gauge" that shows the requested and actual valve lift/duration?
Well, since the ECU controls the VVEL module using a dedicated CAN bus... that got me thinking.

From a past trip to the scrap yard, I have a VVEL module which I wired up to a G37 ECU on my test bench. This allows me to verify wiring and CAN bus IDs by module.
There are just over 1,200 CAN bus messages per second *just* on the VVEL CAN bus, which is a data exchange of about 170,000 bytes per second.

The next step it to record my G37's VVEL CAN bus and then start the reverse engineering!!

NOTES:
• The "ELM327" looking device is the CAN bus to Wifi tool I made.
• I am aware that the typical tuning apps show these values
However, it may be a useful troubleshooting tool as the VVEL CAN bus messages are sent 100 times per second, so you can see everything that is going with quicker updates than an app.
