Picked up this devil and it's actually a really cool tool with the torque pro app total cost $27. Screenshot of CDS running 2500 RPM on TM panel, motor 2042 RPM. I'm going to get a lot of use from this thing I think.
I put a HUD speedometer on our shop truck when the dash instruments on the trailblazer gave out a year ago, the one you posted is even better.http://rover.ebay.com/rover/1/705-53470-19255-0/1?icep_ff3=2&toolid=10001&campid=5337618551&icep_item=281904662870
I've been looking at these

It plugs into the van OBD port, but since my CDS is van powered it tells me all kinds of cool stuff in real time. Everything available that my ECM supports you can view as it's logging it. I have always done all my own repairs, rear ends, transmissions, etc... So it is a neato addition to the tool chest!What TM do you have that has a Bluetooth port?
