Remote Tuning Process

Pre-Tune Tasks

  1. Check that your car meets the requirements lower down on this page
  2. Load a basemap from the ME website or through MEITE (not required for adjustments to an existing tune)
  3. The car should run on the basemap. If not, please check for mechanical or electrical issues and contact me if you require assistance with troubleshooting.
  4. Review the pre-tune checklist
  5. If the car runs, log the car starting and idling up to temperature. If it is drivable, please also log a short drive. (See here for how to make a log)
  6. Save the calibration file from the ECU
  7. Purchase the Full Remote Tune or Basic Remote Tune
  8. Fill in the tune information form (please ensure you have log and calibration first)

Tuning process

  1. We will review the form and files and check that there are no problems which would prevent tuning. We will then contact you with payment details.
  2. We aim to send each updated calibration file within 48hrs from receiving log data and this will be shared through Google Drive.
  3. After each updated calibration file, we will require you to make a new log. The more driving you can do in each log, the more we can refine the map.
  4. Each time you drive the car with a new calibration file, you should notice an improvement. We will continue to iterate until the car drives as well as possible with your individual engine and setup. 

Requirements

  • Motorsport Electronics ME221 or ME442 ECU
  • Wideband AFR gauge
  • Windows laptop with at least 30 minutes of battery life
  • Boost solenoid fitted for turbocharged cars wanting more than wastegate boost pressure
  • A knock sensor is highly recommended but not essential (all MX5s from 1999 onward have a knock sensor installed from the factory)
