I picked up a cheap OBDII reader to work with my data logging software:--
Amazon.com: ELM327 Bluetooth OBDII OBD2 Diagnostic Scanner Can ELM 327 Scantool Check Engine Light Car Code Reader: Car Electronics
Seems to work great on a RAV4 and a BMW 328i, but on a 2006 Boxster I see the OBD clock running, but no data--coolant temp, fuel pressure, revs, etc..
Does anyone have any experience with one of these devices ( or similar) on a Porsche?
Thanks for any help.
