We visited Davis Technologies at the 2021 PRI show in Indianapolis and were pleased to hear about a new feature within Davis’ new VPS (Vehicle Position Sensor). The VPS houses multiple sensors that gather data on several different things that happen during a run. You can look at the pitch, roll, and yaw of your vehicle as it makes a pass.
This data is sampled at a very high-frequency level, so it’s very accurate thanks to the G-meter inside the VPS. You can use the VPS for wheelie control since it has the ability to communicate with your vehicle’s ECU and pull timing to prevent a potentially disastrous wheelstand. We’ve covered the VPS and all of its functions in detail, and you can see that article right here.
For PRI, though, Davis Technologies offers a new feature within the VPS which is going to be great for every racer that uses it. For those of you who read, monitor, and log your pitch, yaw, and g-meters, you’re now able to set limiters on this. Per Shannon Davis, Owner of Davis Technologies, “With this new free update, you can set limits and triggers. You can set a yaw rate or a pitch rate and wire it to set the parachutes off, set a rev limiter, or pull power.”

Another great feature of the VPS is the virtual timeslip function. It is an amazing tool that racers can use to keep track of each pass. The VPS will calculate velocity multiplied by time through its sensors to provide your elapsed time to a certain distance, with incredible accuracy. This function is very useful to have if there’s ever a timing system error, or you leave before the tree is activated. Thanks to the virtual timeslip function, you won’t have another wasted run without a timeslip again.
Davis went on to explain that this was doable before but not within the VPS. Now the VPS has a screen that offers adjustments to each of these areas. “If your car is seeing X of pitch or X of yaw, you may want to do something. Now you have that option within your VPS,” Davis said. “You can set the limits and triggers on distance traveled and lateral distance traveled, it really just depends on what systems you have in the car.”
