Hey all, I'd like to buy a Scan Guage II which hooks up to the OBD2 port and tells you instant fuel economy and a whole bunch of other things. I'd like to do this to increase my fuel economy. Will it work on my setup? I'm running a Type S engine in my lude which has been converted to OBD2a by swapping over all the required parts. I wanted this so I can pass smog inspections. In order to get tuning though, the whole rest of the time I use an OBD2a to OBD1 conversion harness and run a P72 ECU with Hondata S200. So does anyone know if the OBD2 port works with any scan tools when the P72 is plugged in? Thanks!
