This is going to be a tough one, but here I go.

I have an LS6 in a Porsche 944 and want to install a CAN Bus data logger. I know GM did not provide CAN Bus on its PCM's till 2006, and I'm trying to figure out if there is a way to convert ODB (J1850-VPW) to CAN.

Has anyone hooked up a CAN Bus logger to an early GM LS PCM?
