Softronic will send all tuning information / files via email to each customer upon ordering with the end goal being the best possible tune for your Porsche.

Do I have to take my car somewhere to flash it?
No!  You can do it in the comfort of your own garage at your convenience. The included DimSport MyGenius handheld device interfaces with your OBD2 port to deliver the tune to your vehicle. Upon receiving the order, Softronic will ship your tuning device to you within 1-2 days after the order is placed via ground shipping. Please contact us for time sensitive orders. Instructions are sent via email to guide you through the process which summarized is as follows:

  1. Download Dimsport software to your PC
  2. Update software and Dimsport
  3. Connect to car and read ECU file
  4. Send ECU file to Softronic via email
  5. Receive tune file back and then upload to car.

What octane are these tunes compatible with?
Files are tuned to work with street gas ideally between 91 octane to 93 octane. When using race fuel please contact us to ensure tune will maximize its potential.

How do I return my car back to the stock tune?
Your stock file is saved in the DimSport when you pull the file to send to Softronic. It can be flashed back at any time via the same method the ECU tune is flashed to the car.

If I add an exhaust or intake, do I need to reflash my car?
No.  Softronic goes through and tunes each individual table. Unlike others that do a global change to files, Softronic enables the ECU to adapt to basic bolt-on modifications like exhaust, intake, headers, etc. The only time you need to re-reflash your vehicle is when you change fuel components, turbo sizes, or engine internals, etc.


  • Each tune is paired with your specific vehicle and can only be used on one vehicle.
  • Have any questions? Concerns? Contact us at any time to discuss upgrading your vehicle.

    Just wanted to personally say thank you very much for this ECU race tune file you sent! This has completely transformed my car! Your instructions were very clear, and easy for me to follow. The flashing went smoothly. Even though I did notice a CEL code just like you mentioned may occur, I knew I had nothing to worry about, so I just cleared the code with my icarsoft code reader…just for the reference, the CEL code was: “ U0100 Lost communication with ECM/PCM a”.

    I figured it was just due to the ECU needing time to re-adapt to the new files. I’m a novice when it comes to these things, but all I can say is “WOW!”…just “WOW”! the combination of my Soul Performance competition exhaust/header package, Softronic race tune, and IPD plenum/GT3 throttle body has all been a match made in haven!..every time I get in my car and hit the gas pedal, the smooth acceleration just puts a smile on my face!..The car literally feels like it’s on steroids!. I now look for any reason to make “store runs” for my fiancée lol.

    You and John from Soul Performance have both made my whole summer!..you’ve both gained a customer for life!

    Thank you both again from the bottom of my heart!
