  • This is not a physical/shipped product.  This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.
  • While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle!  
  • You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.
  • Fabspeed Motorsport saves your stock/factory ECU settings so that we can convert or flash your ECU back to stock settings at any time for a small fee.


Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser.  The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with.  (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground.  If you ship it via Overnight, we will ship it back via Overnight.)
