I am currently working on a project where I am trying to set the gauge values on an IPC from a 99 Vette, its stand alone outside of a car. I have the circuitry that allows me to send and read the class 2 serial data. I have found some of the commands online and I have been able to get the DIC to display door and trunk ajar. I was hoping someone had access to the data commands to set the water temp, the fuel level, and the oil pressure gauges. Is there someone who has access to a class 2 serial data sniffer that could record the first few minutes of a power up cycle, or is there someone with a Tech2 that can find the commands that set the gauge positions?
Thanks
