What we take on.

Custom ECU and TCU calibration for BMW turbo platforms, tuned remotely from your data logs and revised until the car runs clean and on target.

01

BMW ECU Tuning

Custom engine calibration for your exact setup

Remote ECU calibration matched to your chassis, hardware, and fuel. We tune to your logs. Boost, fuelling, ignition, and load are dialed in for your car rather than a generic file.

Applies to Stock turbo, hybrid and single-turbo builds on any supported platform

Included

  • Stock, hybrid, and single-turbo calibrations
  • Pump gas, ethanol blends, and flex-fuel options
  • Calibrated from your data logs, revised until clean
02

BMW TCU Tuning

Faster, firmer ZF 8-speed and DCT shifts

Transmission calibration to handle more power and sharpen shift behaviour: higher torque limits, quicker shifts, and improved launch and lock-up strategy on supported gearboxes.

Applies to Cars on supported ZF 8HP and DCT gearboxes

Included

  • Raised torque limits to match your ECU tune
  • Faster up and down shifts, improved part-throttle behaviour
  • Supported on common ZF 8HP and DCT platforms
03

Remote Tuning

Worldwide, no dyno appointment required

Flash a base map with supported software, data log your car, and send the logs back. We refine the calibration and return revisions. The entire process is done remotely on your schedule.

Applies to Anyone with a supported flash tool and somewhere safe to log

Included

  • Works with MHD, bootmod3, and other supported tools
  • No travel or shop appointment needed
  • Clear logging instructions provided up front
04

Data Log Review

Know exactly how your car is running

Send a log and we review the fundamentals: air-fuel ratio, ignition timing, knock activity, boost target against actual, and fuel pressure. You get told what is healthy and what needs attention.

Applies to Owners on any tune, including files bought elsewhere

Included

  • Full-throttle and part-throttle log analysis
  • Plain-language summary of what we see
  • Recommendations before you add more power
05

Custom Tune Revisions

Your tune keeps up as your build changes

Added a downpipe, switched fuel, or installed new hardware? We update your calibration to match. Revisions are part of dialing in a safe, consistent tune for your setup.

Applies to Existing Synergy customers changing hardware or fuel

Included

  • Updates for new hardware or fuel
  • Re-calibration from fresh logs
  • Iterated until the car is on target

Custom MHD tuning by platform

Platform-specific pages for MHD-based custom calibration, with the packages, supported hardware, and process for each engine.

Services FAQ

What BMW tuning services do you offer?
Custom ECU tuning, TCU (transmission) tuning, remote tuning worldwide, data log review, and ongoing custom tune revisions for BMW turbo platforms including N54, N55, S55, B58, S58, and S63.
Do I need a dyno for a custom tune?
No. Tuning is done remotely from your data logs. You flash a base map, log your car, and we refine the calibration from the data. No dyno appointment required.
What is included in TCU tuning?
TCU tuning raises transmission torque limits to match your engine tune and sharpens shift behavior, including faster shifts and better lock-up and launch strategy, on supported ZF 8-speed and DCT gearboxes.
How do I get started?
Send your build and fuel through the quote form. We confirm the right calibration for your platform and walk you through flashing and logging.
