I have done the simple traction control module, well, PCB for now, based on ATmega128. It has 4x20 LCD incorporated, 2 UARTs, SPI, 7 0.5A outputs, 7 analog inputs, digital inputs/outputs, etc..
The primary goal is calculating wheel's speed, and putting the information to the VEMS. The secondary goal is calculating 0-60-100mph, 100-200kmph, 0-200-400-1000m, average consumption, trip times, etc...
Question: AIM protocol on VEMS doesn't have all the information. Can the AIM protocol be expanded for this information (injector time, etc)?
