GPEC5 ECU Tuning and Remapping Software: Introducing Our New RFT Service

Flex Update: New RFT Service

Introducing our new Ready for Tuning (RFT) service for Continental GPEC5 control units found in Jeep, Dodge, and RAM vehicles. This update is a game changer for professional ECU tuners seeking to enhance vehicle performance.

As of today, Flex now supports OBD programming of these ECUs, enabling seamless map area modifications that optimize engine performance, boost power and torque, and reduce fuel consumption.

How the RFT Service Works

To utilize the new OBD protocol, simply request the Ready for Tuning (RFT) service via your Magicmotorsport account. After this, send your ECU to our labs, where our skilled team will execute a professional and certified unlock. Subsequently, your unit will be returned fully prepared for programming with Flex.

Accessing the RFT Service

If you hold an active Flex FLS0.5 Master or Slave license, you’re granted direct access to this invaluable service—no additional steps required. For those without a Full license but with an active subscription, you can:

  • Purchase the RFT license as a single transaction.
  • Upgrade your license to Flex Full.

For further inquiries, connect with our sales team at [email protected], access our online chat, or open a dedicated support ticket.

Helpdesk Coin System

All technical services, including RFT, operate on our Green Coins system. Clients with an active Master subscription receive 300 Green Coins monthly, ample for a free unlock request. Need more? You can purchase additional coins anytime through our Helpdesk platform.

Supported Vehicles:

  • Jeep Gladiator 3.6L Pentastar V6 280PS
  • Jeep Wrangler 3.6L Pentastar V6 280PS
  • Ram 1500 5.7L HEMI V8 e-Torque 390PS

  • FLS0.1S – SW Flex ECU (car, van, bike) OBD/Bench Slave
  • FLS0.5M – SW Flex Full Master
