You just discovered the "Kickdown" switch, it took me a while as well to figure it out, here is an excellent explanation about it:
Read this informational provided by the memeber Davidval18isnt this "switch" only on automatic cars?
You should go read the installation instructions again. See the section under Ultra Gauge Set Up - Compatibility - Power Off Detect Mode. It takes a little trail and error to get the correct settings. Don't forget to also set the Power off retries, it is in the same information area as the Power off Detect mode.How the hell did you get your ultra gauge to work in a Mazda 3, I have one plugged it in will work but will not turn off once the car is off it just stay on. Please help me get it working.
It would take a few daaaaaaaaaays possibly weeks for that to happen. Read the specification of the UG . :laugh2:You'll have to remove your cable from the ODB2 serial or it'll drain all the power of your battery.
Or maybe There is a switch ?
