I am selling a silver Blitz R-VIT Type I Gauge for $300 obo. I had it on my STi and it would monitor:

Boost, Injectors, Water Temp, RPM, Speed, Battery, Intake Temp, Ignition, and some other stuff. Check http://www.blitz-na.com/Blitz_RMonitor_Rvit.htm for a full list and pictures.

Installs easily by plugging into OBD-II port.

Will also work for most imports (Evo, RX-7, etc) except Nissan and Toyota.

I am in Fremont. Let me know if you have any questions.
