I got mine at the Fort Wayne truck stop for $1.00. Bought two gave one away, still have one to give away. Not needed anymore. I have the switch that RPMs can now be adjusted with Cruise control.
It's called Bantering. Also I think that Banter was one of the reasons behind the carrier forum. You know, so everyone does not have to read through the Banter, and how great thou are. Lol
You should be able to reset it on the fly without pulling over. When I had my inter cooler leak, before I started my run I would leave it plugged in and menu over the 'reset'.
You can release it by the little flapper door below the shifter. Just fine something to stick in the hole. Foot on brake and push down and shift. Oh never mind, thought it was yours. Carry on.
