  1. Depending on your particular setup, M-Engineering will have given you a base map to run the car on. These are generally not power maps, but they are safely put together to make sure the car is running properly. Flash the base map using M-Tuner to start the car.

  2. Start the car and begin datalogging via M-Tuner. Run the car and record a WOT (wide open throttle) pull all the way to redline. We are generally looking for 4th gear pulls in their entirety unless otherwise specified. Once the pull is complete, bring the dyno safely to a stop.

  3. Stop the datalogging. Pull any information from the dyno regarding power figures and other metrics.

  4. Send the datalog (.csv and .ldat) and dyno information/graphs to M-Engineering via email.

  5. M-Engineering will review the data and send back a map revision.

  6. Flash the new map revision to the car.

  7. Repeat steps 2 through 6 until the tuning process is complete.

  8. Remove the vehicle from the dyno and make sure dyno mode is turned off before driving on the street.

  9. Depending on your situation, we advise running the car on the street (closed course) to confirm vehicle operation. Feel free to datalog the street driving and have us confirm the logs look good.

  • If you notice misfires while running the car or feel it is not running correctly, STOP. Do not push the car, please send us any datalogs you have and await further instruction.

  • Heatsoak can be an issue, from time to time we need to let the car cool down. Opening the hatches or removing engine covers can help with heat soak. 

Important Notes regarding your trip to the dyno.

  • If tuning for only 1 type of fuel, come to the dyno with a full tank of gas.

  • If tuning for multiple fuel types, arrive at the dyno with 1/4 tank of gas and multiple jugs of fuel for the other types. For example, bring car to dyno with 1/4 tank of pump gas for the pump gas tune, and bring 15 gallons of 100 octane for the 100 tune. The idea behind this is to tune the pump gas first and use up as much as we can, so that the race gas is not “diluted” by the pump gas when it comes time to fill the car.
