About Open Road Ace: GPS Rally Timer
Open Road Ace is the pacing app for open-road racing — Big Bend Open Road Race, Silver State Classic, Sandhills Open Road, and the rest of the calendar. It tells you, in real time, exactly how to drive the course to hit your target class speed within a fraction of a second.
A NEW LOOK, BUILT FOR THE DASH
Version 2.3 brings a redesigned interface made to be read at speed from a mount: a flat dark ground, one big number, and a pace ribbon where a small car (you) chases a rabbit (your target). Green means speed up, red means slow down. Before the start you see your distance to the start line. The screen stays at full brightness while the app is open.
THE RABBIT TELLS YOU WHERE TO BE
At the start of your race, a virtual rabbit sets off down the polyline at your class target speed. Your job is simple: keep the rabbit close. The app shows you, in feet, exactly how far ahead or behind you are at every moment. Match the rabbit and you'll cross the finish gate at your perfect time.
WIN ON TIME, NOT SPEED
Open road racing isn't about the highest top end — it's about hitting an average. A 100 mph class is won by the racer who covers the course in 100.000 mph average, not the one who runs it the fastest. ORA does the math so you can focus on driving.
CM-LEVEL RTK PRECISION (NEW)
Open Road Ace now supports ArduSimple RTK — the ArduSimple simpleRTK2B (u-blox ZED-F9P) over the BT+BLE Bridge. L1/L2 multiband, NTRIP corrections handled in-app, with the F9P consuming raw RTCM3 or SPARTN bytes from any standard caster (PointPerfect Flex, regional bases, etc.). Result: ±0.02–0.5 m horizontal position, ~10 Hz update rate, finish-gate timing accurate to single-digit milliseconds. The entire RTK rig is under $500 — an order of magnitude cheaper than the survey-grade rovers most racers have been forced to use.
GPS-PRECISION FINISH DETECTION
The app detects your start and finish gate crossings geometrically and corrects for your antenna's distance from the front of your vehicle. The result: finish times accurate to milliseconds, not seconds.
WORKS WITH YOUR GEAR
- iPhone built-in GPS — works anywhere, no extra hardware
- RaceBox Mini S / Micro — 25 Hz, ±2-5 m
- ArduSimple RTK (simpleRTK2B + BT+BLE Bridge) — multiband L1/L2, ±0.02-0.5 m with NTRIP corrections
You can configure two GPS receivers simultaneously and ORA will fuse them for redundancy and precision.
BUILT-IN COURSES
- BBORR Northbound (Sanderson → Fort Stockton)
- BBORR Southbound (Fort Stockton → Sanderson)
- Buffalo Bayou 45 (Houston practice)
- Short North / Short South (Fort Stockton practice)
Plus you can import any GPX file as a custom course or record a new one by driving it.
MULTI-LEG SUPPORT
Two-leg events like BBORR are scored on cumulative delta across both runs. ORA tracks each leg, applies offsets between legs (auto or manual), and shows you the combined event delta on the finish screen.
GUIDED SETUP, EVERY RACE

Latest updates
2.3.13
Rabbit fix for BBORR and NORC: the rabbit now crosses the finish line right on your target time. It used to pace to the end of the course map, which runs a little past the surveyed finish line, so riding it put you about half a second early. Your scored result was always correct.
Two GPS units: the unit with the best signal now times the finish, and the live delta is smoother when both are connected.
2.3.12
SkyPro / Dual XGPS160 and ORA box: the run clock now follows the receiver's fastest GPS updates, so a timed start goes green on time even when Bluetooth gets busy.
Also fixes a rare crash at the start of a run.
2.3.11
SkyPro / Dual XGPS160: the app now reads GPS time straight from the receiver. Timed starts go green on their own again, and runs are timed on the receiver's GPS time instead of the phone's clock.
Two-leg events: tapping X after leg 1 now asks whether to reset that leg or end the event, and leg 2 picks up correctly if the app was closed between legs.
