We can tune just about any vehicle that can run a MegaSquirt ECU! This service includes a full base tune with up to 5 free updates based on logged data.

For the updates, we will need the following parameters logged: (the parameters may be worded differently depending on your MS version and logging software)

  • Time
  • Vehicle Speed (if equipped with VS sensor)
  • RPM
  • Air to Fuel Ratio (or Lambda value)
  • Manifold Air Pressure*
  • Throttle Position*
  • Load

* Only necessary where applicable.

The more data you can log, the more we can work with, but logging too many parameters can slow down logging frequency. It’s best to keep logged parameters fewer than 20.

When filling out the order form, under “ECU” please include your MegaSquirt hardware and software version! If you need help finding these things, please consult the MegaManual.
