Remote Dyno ProTuning / E-Tuning Procedure for Porsche M-Tuner

This article covers the procedures of having M-Engineering complete a dyno tune remotely with M-Tuner. Remote dyno tuning requires the purchase of a ProTune from M-Engineering. This does not include the cost of a dyno rental. This article does not cover dyno operation instructions. Dynos should only be operated by trained professionals.

Disclaimer: You accept responsibility and risks of any tunes and added features by M-Engineering. If you are not the end user of the car, you will be solely responsible for notifying the purchaser and/or customer they also accept the responsibility and risks of these and M-Engineering is not liable. M-Engineering is also not liable for voided warranties due to installation of our products. 

Pre-Dyno Inspection

Before dyno tuning, it is advised (in some shops required!) to have your dyno operator or shop complete a pre-dyno inspection.
A pre-dyno inspection will:

  1. Check for any kind of fluid leaks on the vehicle that may present a safety hazard for dyno operation or operation of the vehicle.

  2. Perform a pressurized smoke test or boost leak test to insure there are no boost or vacuum leaks.

  3. Check treads on the tires and inspect suspension components related to operating the vehicle safely on the dyno.

  4. Confirm operation of any auxiliary systems (for example, methanol injection or nitrous).

Scheduling a Dyno

Please schedule your dyno appointments with M-Engineering at least one-week in advance or more, if possible. Our email is info@m-engineering.us. You will need to confirm that your dyno cell and dyno operator is also available at those times as well. Since dyno tuning is remote and can be completed from anywhere around the globe, please make note of the time zone when scheduling.

If you are unsure of where to find a dyno, please visit our Dealer Portal or ask your local speedshop.

Dyno Setup

Porsche 992 and 982

It is important to be mindful of the drivetrain setup of your particular Porsche. Some models such as the Turbo and Carrera 4 cars are AWD. These cars can be run on linked or unlinked dynos as well.

Porsche Dyno Mode

If running on a 4WD linked dyno, Porsches can simply have traction control turned off. For unlinked or 2WD dynos, it is required to put the car in dyno mode via a Porsche PIWIS 3 tool. Any Porsche dealership will have this tool and most Porsche indy shops will have access to this tool.

Under no circumstances is Dyno Mode to be used when not on a chassis dyno! All stability control features are disabled whilst the vehicle is in dyno mode. It is common to see a multitude of faults on the dash board while in dyno mode.

Porsche Fans

  • Fans are required at the front of the car. Please be sure these are aimed at the radiators in the front bumper.

  • The 992 Turbo / Turbo S and 982 718 models contain air vents behind the door or on the rear wheel arch. Please insure that fans are blowing air into those vents to properly cool their systems.

  • 992 Carrera and Turbo models have their intercoolers located in the center section of the rear decklid, so airflow directly to there may be difficult. Ideally, it's best to get fresh cool air to the top of the center of the rear decklid, but if this is not possible we recommend having a fan aimed from the bottom of the rear of the car upward. Be mindful not to be directly blowing hot exhaust gasses in the intercoolers as you will just be introducing hot air to the system. 

Dyno Running and Tuning Procedure

Once your dyno operator has confirmed that the vehicle is safely strapped down and secure in the dyno, fans are in place, and RPM setpoint has occurred, the tuning process can begin.

  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.
