What We Do

Our Services

Precision module programming for every make and model.

01

ECM/TCM/BCM Cloning

Exact duplication of engine, transmission, and body control modules. We clone your existing module to a replacement unit — preserving all calibrations, adaptations, and VIN data.

  • Supports BMW, Mercedes, Audi, VW, Toyota, Ford, GM, and more
  • Preserves all learned adaptations
  • Fast turnaround — most jobs same day
02

FRM Repair

Footwell module restoration for BMW and Mini vehicles. Avoid costly dealer replacements — we repair your existing unit.

  • BMW E-series and F-series
  • Mini Cooper and variants
  • No coding required after repair
03

Bench Testing

We test modules off the vehicle on the bench to confirm whether a unit is functional before any repair or programming work begins — saving you time and money.

  • Confirms module health before repair investment
  • Identifies internal faults vs. wiring/harness issues
  • Available for ECM, TCM, BCM, and more
04

ECM Repair

Component-level repair of engine control modules. We diagnose and fix internal failures — blown MOSFETs, damaged traces, corrupted firmware — rather than replacing the whole unit.

  • MOSFET and driver circuit repair
  • Firmware corruption recovery
  • Supports BMW, Mini, GM, Ford, and more
05

Module Programming

OEM-level software flashing for European, Asian, and domestic vehicles. We use factory-level tools to ensure correct calibration.

  • ISTA, XENTRY, ODIS, and more
  • VIN coding and adaptation
  • Remote and in-person options
