Well it finally happened; got 'er out of the garage for the first time and up and down the street.
Quite the thrill.

The only sad part is that in so doing I somehow fried my Koso gauge; once back in the garage, I noticed that the Koso was not registering RPM anymore (even though my android torque app was showing everything correctly). After shutting down I checked and discovered there was a blown fuse to the Koso; replaced the fuse - but now the Koso shows nothing. It doesn't do its normal start up check and no inputs are recognized - no light, turn signals, MIL light, etc.
I called Koso NA and had a brief discussion with their tech help line. They indicated the only way they thought this could happen was if the RPM signal wire to the Koso somehow received full voltage i.e 12V. I now have to buy a replacement device!!
I have checked my RPM wiring and all seems well (the pull-up resistor/tach wire all as it indicated in the LS3 installation manual). I'd like to find the culprit before installing a new one.
Questions: Has anyone else experienced this? What voltage should the tach wire indicate (at the Koso connector) ignition on but engine not running? What should the range of output be for the tach signal wire?
Any help/suggestions greatly appreciated.
