Last month, John Stanley made the shot heard ‘round the world when he cranked off the quickest elapsed time in doorslammer racing history in Las Vegas, going 5.64-seconds to pummel the previous standard of 5.70, and as we soon found out, there was a secret to some of that success, as traction control wizard Shannon Davis of Davis Technologies was on hand assisting the Stanley & Weiss gang at the Street Car Super Nationals and putting laps on a new device he referred to only as the “Profiler.”
Well here at the PRI Show, we got our first official look at the newest peice of hardware from Davis Technologies that Davis firmely believes is going to completely revolutionize the sport, thanks to it’s impressive capabilities and the performance it’s already show on the race track.

The Profiler goes a step beyond Davis’ current offerings, controlling the horsepower to achieve a target wheel speed. This differs from previous iterations of the Davis traction control units, which have tuned the power to reach a target driveshaft or wheel speed. The Profiler, in essence, allows you to both add or remove horsepower, and it does so instantaneously, sampling at over 1,000 times a second and accurate to one RPM.
Using Davis’ software, the Profiler allows for the importaing of data from past runs, which can then be adjusted manually to plot out a profile. The software will create a range of zones, split into an average and two upper and lower ranges, that the user can select to base the profile off of for the next run, thus determining how aggressive the device will add and remove horsepower based on the driveshaft speed during the run. If one adjusts the curve too much, the software can also smooth that curve into a more suitable profile, void of large spikes and valleys of advance or retard in timing.
“We try to provide a great set of tools so the end user can really decide what they want the car to do,” explains Davis.
Continues Davis: “the Profler is not taking away from the tuner or the racer…it’s still up t them to build the plots and set up the timings, but now they know what they build is going to do. If they build it too hot for the track, it’s not going to work.”
To combat this, Davis and company can incorporate self-learning traction control into the unit, and for higher horsepower cars the likes of John Stanley’s screw-blown Pro Modified, this is exactly the setup that Davis suggests, and in the future, these components will be combined to deliver various levels of all-in-one products.
The Profiler features both USB and Bluetooth for transferring profiles to the unit from your laptop computer, and Davis hopes to outfit the unit wth enough storage to hold five run profiles at once.
And if the shape and size of the Profiler looks familiar, that’s because it is. Davis designed the unit, which is the first product from Davis Technologies to feature a built-in touch screen for cycling through the stored profiles, to fit right on top of an MSD Power Grid, using the very same bolt pattern. Because most racers would put the two units near one another, this option allows for removing clutter by stacking the two units.
While assisting Stanley in Las Vegas, Davis was able to quickly dial in the Profiler and from there, the car repeated within a few hundredths of a second run after run. Interestingly, West coast hitter Mike Maggio is also one of the early adopters of the unit, and he too ran in the 5.60’s, making the only two door cars in the world to run in the 5.60’s Davis Profiler-equipped. Quite an introduction, we’d say.
