I have this unit in a Kia Soul and it has worked great for two motor homes, one of which is a DP. Will also use it for our new Tiffin Allegro Bus 37AP when we get it in mid-January! Our first coach was a NAVION IQ so we needed this one, not the air force one, but it works just fine with our air braked coach - have put about 9,000 miles on the current rig in the last year.
Step 12: Adjusting the G-Force Controller
Note: The Stay-IN-Play Duo’s activation is progressive in nature. It is designed to activate
briefly in normal stopping (20+ MPH) and longer in harder/panic stopping. When
adjusted correctly, the Stay-In-Play DUO WILL NOT activate while stationary.
1. Locate the vehicles on level ground and turn the switch to “ON.” Place the black knob on
the G-Force Controller at the bottom of the slot and have an assistant step on the brake
pedal of the coach. At this point the system should activate. If it does not, remove the
front screw from the G-force Controller and lower it until the unit activates and then resecure
it in this location. Slowly raise the knob up. The system may begin chattering,
keep raising the knob. As soon as the pump shuts off completely and then go up another
1/8”. Tighten down the black knob to ensure it does not move.
2. Test drive the coach while pulling the towed. Drive and stop NORMALLY as these are
the conditions for which you want to configure the braking system. The system should
not come on in normal stopping below 20 mph.
3. If while traveling the system activates too often, raise the knob 1/16”. Repeat step 2.
4. If while traveling the system doesn’t activate often enough, lower the knob 1/16”. Repeat
*The DUO system operates the brakes of the vehicle in the same manner as you would.
The more often it comes on, the more quickly the brakes of the vehicle will wear. The
above adjustment will equal normal driving mileage on the brakes.
