OK guys, I have not been able to get Garratt or anyone else to help with the serial link or CAN bus link to get at the relevent data on our cars. I am now going to go another route.

I am plan to connect directly to the signals feeding our systems, looks like it has most everything we need.

I can see the following signals.

ABS
yaw sensor
steering angle
4 wheel speed sensors
brake pressure (I think)

MFI
oil temp
oil pressure
throttle valve position?
engine speed
charge air temp
charge air pressure

Has anyone done this or am I blazing the trail? Any suggestions or input?
