Stock: the factory target boost map of a 2006 Subaru WRX, 800 to 6400 rpm across, throttle 14 to 95% deep. Tuned: our example remap.

Look up a car to see which ECU it runs and what each stage could add. Our catalog lists 142 makes, 10,633 engines and 971 ECUs.

Four steps, from your original read to a calibrated file.
  1. Step 01

    Send

    Read the ECU and upload the original file with the vehicle details and your hardware.

  2. Step 02

    Brief

    Tell us the stage and what’s fitted. When a stage needs supporting parts, we say so first.

  3. Step 03

    Calibrate

    Boost, fuel, ignition and torque limits are recalibrated map by map, inside the hardware’s limits.

  4. Step 04

    Download

    Download the calibrated file and write it back. Your original stays on file.

ECU remap
Stage 1 to 3 files, calibrated for the hardware on the car. Send the read, pick the stage that matches the build.
Stage 1Stage 2Stage 3
TCU / gearbox tuning
More torque is only half the job. Send the TCU read too, and the gearbox gets its own calibration.
Custom calibration
No off-the-shelf file. A calibration written to your brief, for the car on your bench.

  • Launch control

    Holds the revs on the line, so the car leaves hard, the same way every time.

  • Pops & bangs

    Fuel on the overrun when you lift off, for the crackle on the way down the revs.

  • Speed limiter removal

    The cut at the top comes out, for the track and private ground.

  • Map switching

    Two calibrations on one ECU, switched from the driver’s seat.

Look yours up in Find your car above. If it is not listed, ask us anyway: the catalog grows with the cars we see.

Find your car

Stage 1 is calibrated for a standard car. Stage 2 and 3 are for cars with upgraded hardware, such as intake, exhaust, intercooler or turbo.

What we calibrate

A calibration works inside the limits of the hardware. We check the read and the brief first, and say when a stage needs supporting parts.

Ask about your car

Yes. The original software is read and kept before anything changes, so it can be written back.

We record stock and tuned runs on a Dragy and list them above, many with the Dragy screenshots.
