I have a Scan Gauge, but I don't know how to program it to change the beeps. Primarily I use it to monitor the temps and RPM's. Is there a step by step thread on PC that tells this. So far I haven't found one. I did see the chart for the codes, but don't understand how to change them and I'm frightened to do something that will mess up the computer. I'm using it on a 2010 Prius V. Thanks, Fred
