YOUR PHONE.
YOUR CAR.
A REAL DYNO.

Measure power and torque on the road with two independent calculation channels and a confidence score. No pretending — every result tells you whether to trust it.

The honest difference

Three approaches. One is honest about what it can — and can't — do.

Other phone apps
  • Single number, no context
  • Often wildly optimistic
  • No way to know if you can trust it
Pro chassis dyno
  • Trustworthy but inflexible
  • €200 / session
  • Drive to a shop, book in advance
DynoPulse
  • Two independent channels
  • Cross-validation = confidence score
  • Anywhere, any time, your own car
Under the hood

Four channels. One number you can trust.

DynoPulse runs two completely independent power calculations from different sensors, then cross-validates them and tells you how much they agree.

A
Kinematic

GPS Doppler speed → derive acceleration → solve F = m·a + drag + roll → P = F·v / (1 − loss). Pure physics, no engine assumptions.

B
Combustion

MAF (or speed-density synthesis from MAP) × lambda → fuel flow → thermal efficiency → engine power. Independent of GPS.

C
Cross-validation

| A − B | ÷ A → percentage. < 5 % HIGH ●●● · 5-10 % MEDIUM ●●○ · 10-20 % LOW ●○○ · > 20 % BAD.

D
ISO 1585

Cf = (990 / P_baro) × √(T_K / 298). Normalises a winter run so it's comparable to a summer run. Same standard pro dynos use.

What you get

Every run becomes a one-page PDF you can share

Modelled after pro dyno report layouts, generated automatically after each run, ready to email or post on a forum.

Vehicle, plates, mass, conditions, confidence — all at a glance.

Three peak blocks

Power, torque, ISO-corrected. Both kW + hp, both Nm + lb-ft.

Combined chart

Power and torque on one panel. Solid line for GPS channel, dashed for MAF channel.

Wind effect strip

Direction, headwind component, expected impact on the reported number.

Diagnostic hints

If channels disagree, the report tells you the most likely cause.
