I just installed the Dynojet Power Vision 3 on my Talon yesterday and haven't had a chance to really try it out yet but it looks like the coolant temp gauge is one of items from a list of 30 different items that works. Doubt if anyone would want to spend 400 bucks for just a temp gauge but I wanted it for the ability to upload tunes. Dynojet claims they have a tune that smooths out the shifts, raises the rev limiter by 300rpm, raises the mph governor among other things, I also wanted to add the launch control tune that they offer (still waiting on that tune). It has 4 gauge screens you can configure, each screen has 4 gauges you can set up. So I added things like RPM, MPH, coolant temp and gear indicator (it also has oil temp gauge but not sure if the Talon has a oil temp sensor yet) to the first screen and my plan was to mount it right behind the steering wheel since the OEM gauges on the Talon are in the center of the dash instead of directly in front of the driver where they should be but the included cable was too short by about 6-8 inches so I had to mount off to the left side of the dash but it is still more visible than the OEM gauges.
Update: Looks like the engine oil temp gauge does work, so a little added info for those interested in that kind of thing and the gear indicator is a nice little bonus whether you are in high or low and in automatic mode since the OEM gauges only read H or L while in auto mode.
