ODBII question
Can a/f, boost, and/or oil pressure be monitored via the ODBII port?
I know I probably sound naive, but if the ECU is regulating/monitoring these through existing sensors, are the results readable without installing extra gauges and tapping pipes, etc? Or, alternatively, are there any gauges that function through the port?

A generic OBDII scan tool can monitor MAP readings which correlate to boost. It cannot show A/F because generic scanners cannot read data from the wideband front sensor. You will be able to see short and long term fuel trims, and the ECU switching between rich/lean status. Oil pressure is not monitored by the ECU.
A Delta Dash would be able to read A/F and boost, as well as all other ECU parameters, but it requires a laptop so you wouldn't want to use it all the time. Also the OBD port is right above your feet so the cable would be in the way unless you relocate the port. There is a digital gauge unit that operates through the port and reads some of the sensors, there are threads about it but I don't have time to look right now, gotta go. |

yea you can, you might take a look atmaxqdata they have a moudual that plugs into that port, then you just plug it into your PDA, and read almost every sensor on your car
