I have just installed a Blitz R-VIT meter, and thought you may like a conclusive list of which features actualy work with a subaru (MY01 WRX JDM).
I will list all the features, and show if they are functional. Some of them I dont know what they are measuring, and others, I need guidance on what the outputs should be.

Speed: MPH or KPH functional
Tacho: RPM functional
Water: degC or DegF functional
Ignit:deg functional
Injct: m/s functional
Intake: degC or degF functional
Air Fl: V functional (what is this?)
In-Mf: HKPa functional
O2: V non functional (just reads max volts constantly, so dont think it is functional)
O2R: V functional (is this the lambda sensor reading? what should it be normaly, and what setting should I set the alarm point for a lean mixture warning)
A/F-C: % functional ( is this the air fuel ratio, is it just a calculated value, should I set a warning alarm on this, if so, what percentage?)
Batt: V functional
Throt: V functional
WGV1: % functional
WGV2: % non functional
AT-FL: degC or degF non functional (doesnt work, but what is it?)
Gear: non functional
4WD: % non functional

If you can answer any of these questions then that would be great, we could come up with a list of settings that other users could use.

Thanks, Rob.
