GPX Pro Timing

The GPX Pro is XT Racing's newest addition to its line of precision racing electronics. With up to 5 channels of data acquisition, GPS lap timing and GPS track mapping, the GPX is no ordinary lap timer and it packs the punch of a system twice as expensive.
Manufacturer: XT Racing

XT Racing is proud to introduce the newest in its line of precision racing equipment, the GPX Pro. Packed with features designed to give you superior insight into your time on the race track, the GPX Pro isn't just a lap timer, it's a professional-grade racing tool with the club racer's budget in mind.

At XT Racing, we understand that in order to be a valuable tool, the GPX Pro needs to be versatile enough to log the data a racer wants while being adaptable enough to handle many different forms of racing. With the GPX, you don't have to wonder if it was designed for your kind of racing. At up to 5 channels of data acquisition and with four separate racing modes, the GPX assures that if it can be raced, a GPX belongs on it.
The GPX is literally jam packed with features previously found in models hundreds of dollars more expensive.

You'll wonder how you ever raced without one.


Have you ever felt like you were on a fast lap only to find out that you were actually going slower? With the data gathered from just one lap with a GPX Pro, you'll be finding tenths before you know it. Add a segment at the beginning and end of each turn to isolate your problem areas or, with GPStudio, overlay one of your faster friend's laps on top of your own so you can see how they're doing it.
Out of the box, your GPX will come ready to race. Just strap it to your vehicle and let it take care of the rest. After your first lap, its automatic start/finish detection will read the completion of a lap and start logging data. Gone are the hassles of setting up a trackside beacon or walking out on track to set your start/finish manually.

Circuit Spinner
Out of the box, your GPX circuit-mode spinner is set to display your RPM, speed, gear position, lap number and running lap time. As with almost every other facet of the GPX, this screen is fully customizable and can be moved around and customized to your heart's content.

Track Map
For each session recorded in Circuit Racing mode, the GPX has the ability to graph a map of the track on screen, without even uploading to your PC. In addition, you have the ability to play the lap in real time with your RPM, speed and split times all displayed on screen at the same time.


  • GPS-based lap times to 1/100 seconds
  •  Say goodbye to trackside transmitters! With the GPX, you can race with the confidence that your lap times are being recorded accurately without the hassle of setting up and powering a trackside beacon. 
  • Track maps with full data analysis capabilities
  • Ever find yourself struggling to pick up tenths on the race track? Let GPX's mapping and data analysis give you a hand. By allowing you to see things like your throttle position, RPM and speed through the turns, you'll know exactly where you have room to improve.
  • Min/Max RPM and speed for each lap
  • With GPX's Min/Max RPM and speed feature, you'll be able to see exactly how hard you pushed each lap to go faster.
  • Automatic track recognition and start/finish line setup
  •  After running just two laps on any circuit, GPX will then automatically recognize the track and calibrate a start/finish line for you anytime you return; no hassle or setup required.
  • Add up to 5 splits and adjust them at any time
  • GPX allows you to create up to 5 split segments that you can adjust at any time. Having a problem with a specific turn? Place split times at the entrance and exit in order to compare your performance from lap to lap and better locate that perfect racing line.
  • Store hundreds of laps and sessions
  • With GPX's onboard memory, have an entire season's worth of racing for review right at your fingertips.
  • Tachometer input with digital pickup or inductive wrap
  • GPX is versatile not only in the amount of information you can record, but how you can record it. It is your choice. Record RPM either with a digital pickup or an inductive wrap around your spark plug wire.
  •  8 Adjustable LED RPM and shift lights
  • GPX's LED tachometer can be calibrated and customized to fit the tastes of any racer. Program not only how you want the LEDs to flash but also calibrate them to suit each individual gear.
  • Hour meter and total miles/kilometers traveled
  • Have more than one vehicle or engine? Keep track of exactly how far and how long you've driven each motor to help keep maintenance up to date. Prevent unwanted blow-ups and missed races by knowing exactly where your engines stand.
  • GPS speed and 5 data acquisition channels
  • With its GPS chipset, GPX logs your actual land speed with precision, even after gearing changes. With its 5 channels of acquisition and flexible digital/analog recording capabilities, record any and everything you are interested in seeing on your race vehicle.
  • Data acquisition inputs selectable
  •  With GPX, out of the box you have the ability to record gear, throttle position, wheel speed, RPM, temperature, pressure and suspension data... all with configurable alarms.
  •  Built in GPS receiver/antenna or optional external antenna
  • GPX is all about choice and with it, you have the option of recording your laps with either the built in GPS receiver chip or with an external GPS antenna for use in areas where signals are sparse.
  • Huge 240x160 backlit 32 shade grey scale graphics display
  • What good is information if it isn't delivered clearly? With this in mind, the GPX is outfitted with a rich, dynamic, backlit 32 shade graphical display designed to deliver the information you need when you need it.
  •  Design your own screen layouts
  • Customization is a feature close to the heart of the GPX. With the 240x160 display comes the ability to set up the information it gives you in the way the best suited to your needs using GPX's software suite, GPStudio. Arrange your data and even include images or photos to make the GPX your own.
  •  Dimensions - 4.53" (115mm) x 3.07" (78mm) x 0.84" (21.3mm)
  • We know that inside your vehicle, space is a premium. For that reason the GPX has been designed so that it is sleek enough to fit in the smallest of cockpits while still delivering the features and functionality you've come to expect from much larger units, much more expensive units.
  • 3-axis accelerometer records and graphs your racing g's
  • Ever wonder how many g's you were pulling through that carousel? Want to know how hard you were braking into that hairpin? With GPX's 3 axis accelerometer, track your g's through every moment of every lap.
  • Selectable modes - Circuit Racing, Point-to-Point, Drag Racing
  •  The GPX is designed with the racer in mind and realizes that not all racers are the same. With its included modes, there's virtually no limit to the types of racing it will record. From quarter mile to eighth mile to the Baja 1000... GPX will record it all! Drag mode also includes a tree start using the tachometer's LEDs, enabling you to practice your starts and record your reaction times.

Acceleration and braking tests

Can't tell if those brake pads are ready to be replaced or not? Curious what your 0-60 time is? The GPX comes equipped with all the tools you need to answer those questions. With its 0-60, 0-60-0, 0-100 and 0-100-0 test modes not to mention an array of others, you'll have everything you need to calculate horsepower and tune your engine on the fly.

Internal rechargeable lithium ion battery

Forget messing with AA's and buying new batteries, the GPX comes with a rechargeable lithium ion battery that you'll never need to replace. The GPX can also be configured to run off 12v power supplied from your vehicle through the GPX wiring harness.

Fast USB download

With its USB connectivity, have everything the GPX records running in GPStudio in a matter of minutes. With an even wider range of options for data analysis, GPStudio is the perfect companion tool for the GPX. In addition, GPX's USB port will allow you to keep your GPX up to date with the latest firmware updates from XT Racing.
