PRI 2025: Davis Unveils Major Profiler Software Overhaul and Dual-Profiler Support

You never know what kind of stories you’ll hear when you stop by the Davis Technologies booth, but this year the headline isn’t drama—it’s software. Big software. Shannon Davis walked us through what might be the most significant update to the Profiler platform in years, and the best part is this: it’s a free upgrade for existing users.

The biggest change is that the Profiler software now pulls in all VPS (Vehicle Position Sensor) data natively when you download a run. No more bouncing between multiple programs or files. Your entire pass—time slip included—lands in one clean data view. Pitch, roll, yaw, lateral and longitudinal Gs, distance traveled, mile-per-hour… everything is stamped directly into the data log. Even the file names get smarter, automatically labeling themselves with event info and incrementals like 60-foot, 330, and ET. If you already have a VPS on the car, this upgrade instantly ties your whole process together.

Davis Technologies also introduced a new feature called Run Groups, which packages your tune settings and all associated data into one container. That means no more hunting for what was changed, when it was changed, or what tune was loaded during a specific pass—everything lives together in a single, traceable group. And if you don’t already run a VPS, Davis says you can add one to nearly any Profiler system via CAN or serial.

Behind the scenes, this update was a monster rewrite. Davis joked that months of hardcore coding led to a simple user-facing win: the COM ports finally work flawlessly. Anyone who’s ever seen a “Profiler box not found” error knows exactly how big of a deal that is. The new syncing system works more like modern EFI software—plug in via USB and the software tells you what’s different between the tune on the computer and the tune in the box, with clear indicators when settings change.

Another major topic at PRI: dual profilers. More racers are running a primary Profiler on the driveshaft and a secondary on the engine. With this update, users get up to 22 complete tunes in one file and the ability to plot both channels together. Justin Martin and Beer Money are already using the setup, and future updates will make dual-profiler management even more seamless.

Davis expects the updated software to be released in about a month. The team had a working version running at the show, and while it’s still being fine-tuned, it’s clear this update is going to make life a whole lot easier for racers relying on Profiler for traction control and data-driven tuning.
