My 87 GN came with a Scanmaster in it (don't know which version as the car hasn't been used all that much since I got it and when I had my last Turbo Buick in 90-92, these weren't out yet).
Nonetheless, it was working just fine and I was able to use the button to scroll through and see all the data points (TPS, MPH, RPM, O2, etc).
I installed a new TurboTweak chip and now the Scanmaster only shows the O2 voltage - if I push the button to scroll to the other screens, I get dashes across the displays. I don't think I have a wiring issue as I get the one screen with no problem. Car runs beautifully though, I just can't see the parameters!
Ideas?
