DTC / IMMO Off & Tuning

Clean code. Dead immobilizer. Engineered performance.

// OVERVIEW

What this
engagement covers.

Diagnostic trouble codes and immobilizer systems can sideline a vehicle after an engine swap, a donor module, or lost keys. We perform DTC-off and IMMO-off modifications plus software tuning — rewriting the calibration so the vehicle runs clean, starts reliably, and performs exactly as you want it to.

// WHAT'S INCLUDED

  • DTC deletion / fault-code masking for swapped or deleted subsystems
  • Immobilizer OFF (IMMO off) for engine swaps and donor setups
  • Performance & economy software remapping (tuning)
  • EGR / DPF / AdBlue / swirl-flap OFF solutions
  • Speed limiter removal and adjustment
  • Original-file backup and dyno-safe calibration
