I bought a v2 for my diesel endeavors and wanted to play with the wife's 03' 5.3 Tahoe last weekend. Problem is, I get an error code saying no data received (trying to read stock tune). Is there something special I need to do for an LS1B? I did a few minutes of google searches and guys saying their PCM was bad. But the car runs and has been, this is the first that I am aware of it being read/flashed.
