Telemetry & Calibration

Vehicle calibration

Pocket Performance uses vehicle calibration to help the app line up more closely with the way a specific car behaves in the real world. This matters because different vehicles, tyres, gearing, drivetrains, and road conditions can all influence how speed builds and how a run feels when you are trying to put down a clean result.

Calibration is there to help create a stronger testing baseline for that individual vehicle before serious performance runs begin. The result is a phone-only workflow built around consistency, better confidence, and more believable performance measurement.

7-layer telemetry system

Pocket Performance is powered by a 7-layer telemetry system plus vehicle calibration for serious phone-only performance testing. The telemetry stack is designed to work alongside calibration so the app can produce stronger speed, timing, and distance results during private testing and public leaderboard competition.

This is not about fake dashboard theatre. It is about combining a deeper phone-based telemetry approach with car-specific calibration logic so the system is better prepared for serious runs, proof capture, and competitive uploads.

Calibrated speed crossing points

For 100–200 testing, Pocket Performance uses the calibrated speed crossing points rather than asking the driver to hold steady at 100. The timer starts when calibrated speed crosses 100 and stops when calibrated speed crosses 200.

That makes the event better suited to real higher-speed pull testing, where the car may already be accelerating before the measured window begins. It also keeps 100–200 separate from standing-start launch wording, traffic-light start wording, and false-start wording.

For the dedicated explanation of that event, visit 100–200 Acceleration Testing.

Phone-only performance testing

Pocket Performance is built for serious phone-only speed, timing, and distance testing. That means the experience is designed around what a driver can do with their phone and the app itself, without pretending the app is reading hidden ECU channels or workshop-grade powertrain diagnostics.

The focus stays on performance testing that makes sense for the app: run measurement, timing, speed progression, distance targets, in-motion acceleration pulls, proof capture, saved results, and leaderboard competition.

Runs the app is built to measure

Pocket Performance supports the performance figures drivers actually care about when they line up to test a build:

0–62, 0–100, 100–200, 1/4 mile, 1/2 mile, and top speed.

These are the headline numbers used across private runs, saved run history, proof-video uploads, challenge features, and the public boards.

For more detail on those result types, read 0–62 & Quarter Mile Testing.

100–200 and leaderboard confidence

100–200 results rely on a clean measured window between the 100 and 200 speed crossings. Confidence still matters, because a weak or unstable run should not be treated the same as a strong verified result.

Low Confidence or Invalid runs should not be treated as public proof runs for leaderboard, challenge, or brag-card purposes. Verified 100–200 runs can be used for public board competition when they meet the qualifying rules.

The full 100–200 workflow is covered on the 100–200 Acceleration Testing App page.

Proof videos

Pocket Performance can capture proof videos where supported and where the user enables those features. This gives users a stronger way to show what happened on a run and makes public leaderboard uploads more meaningful when a qualifying result is backed by visible run footage.

Proof videos are part of what makes Pocket Performance feel more serious, more competitive, and more built for real rivalry instead of empty claims.

See how that links into saved runs and uploads on the Proof Videos & Leaderboards page.

Leaderboard confidence

Public leaderboard competition is not just about posting a number. Pocket Performance also uses leaderboard confidence as part of the broader public run picture. That helps add more context to competitive uploads and gives users a better idea of how strongly a result stands when it goes onto the board.

What Pocket Performance does not claim to record

Pocket Performance does not make fake claims about ECU data, torque, engine temperatures, oil temperatures, boost maps, hidden vehicle channels, or any other data the app does not actually record.

The system is focused on what it is genuinely built for: serious phone-only speed, timing, distance, calibrated speed crossing, proof-video, and leaderboard performance testing.

Built for drivers who want proof, not hype

Pocket Performance is for drivers who want receipts, rivalries, and real numbers. The combination of vehicle calibration, a 7-layer telemetry system, proof videos, calibrated 100–200 measurement, and public boards is designed to give users a stronger phone-only performance testing experience without drifting into fake feature claims.

If you want to see how those runs translate into public competition, head over to the Leaderboards and compare real posted results across the Pocket Performance boards.
