I have a dm-200 obd multigauge
comes with the dm200(60mm) mount I used to attach to steering wheel
egt sensor
boost sensor
wideband afr
With this gauge you can create custom backgrounds read obd2 trouble codes and all kinds of random stuff like that. I used it for 8-12k or so. When it was purchased it was around $1100 worth of stuff currently sells for $800ish.
I'm asking $500 OBO my car with this installed is sitting at Evolution Dynamics, I would rather do local if possible.
