## PerfExpert Description
Know your car's true performance.

Turn your smartphone into a professional dyno. Measure the real horsepower and torque of your engine — within 2% of a chassis dynamometer — and time your car's acceleration. No OBD adapter, no cables, no expensive dyno sessions. Just mount your phone, accelerate, and get instant results.

Test and compare performance upgrades. Whether you're verifying an ECU remap, testing a new exhaust, or tracking the effect of a chiptuning session, PerfExpert gives you objective, independent data you can trust.


HOW IT WORKS

1. Create your car profile
Enter your vehicle's weight, tire sizes, and gear ratios. Not sure about a spec? The app guides you through every step.

2. Mount your phone & accelerate
Secure your phone in the car — no connection needed. Find a flat, straight road. Accelerate in one gear from low RPM to redline. That's it.

3. Get instant results
Power and torque curves appear immediately, just like on a real chassis dynamometer. Compare runs, track your modifications, and share results.


MEASUREMENT MODES

Dyno — Full power & torque curves vs. engine RPM. Advanced drivetrain loss model, rev limiter detection, and correction standards (DIN, SAE, JIS, CEE, ISO). Results as detailed as a professional chassis dyno.

Timed Run — Measure acceleration from a standing start. Speed intervals: 0-100, 100-200, 80-180, 60-160 km/h — 0-60, 60-120, 50-110, 40-100 mph. Distance: quarter mile, eighth mile (with trap speed), 60 ft. Max speed and peak acceleration on every run.


KEY FEATURES

- 2% accuracy compared to professional chassis dynamometers
- No OBD adapter or connection to your car required
- Works with your phone's built-in sensors
- External GPS available as an in-app option for pro-level precision: RaceBox Mini, Mini S, Micro (rolling start dyno, free phone mounting)
- Power correction norms: DIN, SAE, JIS, CEE, ISO — using real-time atmospheric pressure, temperature, and humidity
- Interactive charts: pinch to zoom, tap for exact values
- Export results as PNG image or shareable web link
- Custom units: HP, CV, kW for power — Nm, ft-lb, mkg for torque — km/h, mph for speed


PERFEXPERT PRO (optional subscription)

- Custom logo on your results

## PerfExpert Reviews in Germany

### ****- "Good package"
I really like to use this app. Works basically like a charm. 
However I’m using a p-gear box for my 100-200, etc. times. 
Anytime soon possible to use this one for dynoing? 
Or maybe something like to enter km/h / time values from any v-box pull to get a estimated power (and torque curve) from those values? 
Should work like the same, right?

### *---- "Doesn’t work"
I have tried it many many times. It doesn’t work, on dyno I have 385 hp with this app 1 time 250hp, 270hp, 190hp....
