Carrot ECU

Carrot C-MX · Dyno · Track · TDM

Your personal map.

On the dyno we tune it to your engine, on the track to you. The Carrot box is the tool, the tuning is our craft.

Carrot builds the box. We tune it.

Together, not against each other.

Carrot develops the ECU and the software. We are a Carrot partner in Germany and a workshop: we advise you, fit the box and tune it to your engine and to you.

Carrot

  • Carrot C-MX replaces the stock electronics without modification
  • “Carrot Management” software
  • Data logging, wiring harness, sensors

TDM

  • Advice and fitting in Polkern
  • Base maps from our own dyno runs and test days
  • Personal map: engine tuning on the dyno, rider tuning on the track

Data becomes your map

This is our own analysis. Every session turns into curves: rpm, throttle, mixture, ignition, injection. That shows us what your engine and you really do on the track.

TDM log review: rpm, throttle, mixture, ignition and injection over one session
Log review from our own analysis, with real data from a race distance. Numbers hidden, they stay in the workshop.

Traceable, cell by cell

After every step we compare the new map with the old one. Each cell shows where we went richer or leaner and where everything stayed as it was.

So every change is documented, and the way back is always there.

TDM map comparison: change per cell in colour
Comparison of two map versions, detail. Green = barely changed (under 5 %), turquoise and blue = leaner, orange = richer.

Three stages to your map

Engine first, then the rider. You start where your bike is today, and every stage builds on the one before.

How a test day works

One step after the other, so it is clear what works.

  1. 1

    Warm-up

    First session on your map. We log and change nothing yet.

  2. 2

    Analyse

    In the paddock: mixture, rpm, throttle, temperature. What does the engine say, what do you say?

  3. 3

    Adjust

    Exactly where data and feel say the same thing.

  4. 4

    Cross-check

    If it helps, it stays. If not, we go back. The old map is always there.

  5. 5

    Race distance

    Finally a full distance: does the tuning hold over time?

Measured on the dyno. Proven on the track.

In the end, what counts is what reaches the track. Heads, valve seats, conrods, gearbox, Carrot: 36 seconds from our workshop.

What we promise, and what we don’t

We promise our part and back it up. Every map version is archived, the way back is always there. Every session is logged, and you see what we changed and why.

We don’t promise your lap time. That comes from you, your bike, your team and us. We are part of it, never the whole.

The maximum that lasts.
