Today I successfully read the ROM off Pearl's ECU. The file has been uploaded to github so people can assist with hacking it so we can tune our VK56VD engines to their full ability.
This is a dedicated thread for this so that anyone interested can assist. To start with I would apreciate anyone who is using a scan gauge or equivalent could post up the hexademical addresses for each of the items in your gauges.
All help is greatly appreciated and credit will be given in the hack or README.
