Will there be CAN at all in VEMS?I work in top level motorsport on a daily basis, and essentially/literally todays race/club cars wouldn´t work without CAN of some sort.
With proper GUI implementation it could be an incredible asset to the ecu and allow VEMS to develop additional hardware to go with it.
number one would be SD card logger via pre-defined CAN stream, allowing high speed logging and instant offloading. It also allows the ECU to be used with any of the video recording loggers for race cars. VBOX , RACE KEEPER and so on, they all accept CAN streams and could receive the basic signals from VEMS.
It would also allow a 1MBIT CAN stream to the Laptop. This can provide high speed logging as well as alot more detailed data stream from ECU - LAPTOP without lack of stream speed.
The possibilities become literally endless.
Output to CAN logger, to dash, to car electronics, gearboxes, diff controllers, other VEMS designed hardware
Input from CAN analog/digital expansion box, from ABS modules ( wheel speeds , ABS activity, G sensors ), from OEM control modules, from Lambda boxes, from EGT sensor boxes and so on and so on.
Ideally ditching the whole AIM protocol to the VEMS round would be the best starting point and use CAN. Any channel from the ecu without limitations could be sent from the ECU to the Round for viewing.

So you would simply load the ecu with a .dbc file and jobs done.
