I have benn using the Tunerview 2 connected to my 1227749 running code $59, since last summer, and it is awesome.

I can have things displayed on my dash that I couldn't or at least not easily before.

AFAIK, the only place to get the interface to use the TV2 with a GM ECM is from http://www.moates.net, that's where I got mine from.

It is currently available to work with $59 and $8D.

Here are some pictures:






It's great to have on my dash, since I can see some specific variables as they are happening, without needing to look down at the laptop on my passenger seat, so it's a little safer, and legal. lol
