ECU & TCU Tuning File Service

Empowering UK workshops, mobile remappers, and master tuning centers with custom, dyno-tested calibration files written in-house using genuine WinOLS software.

Streamlined Workflow

How Our File Service Works For Your Garage

Get files back on your ramp in 3 simple steps via our secure dealer portal.

01

Read & Upload

Read the vehicle ECU/TCU using your slave or master tool, then upload the original BIN read directly into our portal along with your modification requirements.

02

In-House Calibration

Our experienced calibrators review and custom-tune your file using genuine WinOLS software. No blind automated scripts or generic public downloads.

03

Flash & Drive

Receive your modified file back in an average of ~15 minutes, checksum corrected and ready to write straight back to the vehicle.

Engineered For Reliability

Why UK Garages Rely On CB Tuning

We operate out of our fully equipped workshop facility in Glenrothes, Fife, featuring a dedicated 2WD braked Dimsport rolling road. This allows us to test and verify our map developments under authentic, real-world load conditions rather than guessing figures on a screen.

  • Rapid Turnaround: Average ~15 minute turnaround times to keep ramps moving.
  • Comprehensive Tool Support: Full slave support for Autotuner, Kess V3, and Flex, plus all master BIN devices.
  • Direct Engineering Help: Talk directly with our calibration team via WhatsApp and portal tickets.
  • Custom Emissions Solutions: Clean, reliable DPF, EGR, AdBlue, and DTC removal solutions.
