VW Golf R Mk8 Stage 1 & Simos 19.6 OBD ECU Unlock

This Volkswagen Golf R Mk8 went from 320hp and 420Nm to around 405hp and 525Nm with our Stage 1 ECU calibration, a gain of 85hp and 105Nm, after its Simos 19.6 ECU was unlocked through the OBD port in the same appointment.

The Golf R Mk8 as a tuning platform

The Mk8 Golf R pairs the 2.0-litre turbocharged EA888 engine with four-wheel drive. It is strong from the factory and responds very well to software, with much stronger acceleration, more mid-range performance and sharper throttle response after Stage 1, while staying smooth and progressive to drive.

Simos 19.6 ECU unlock without removing the ECU

This Golf R had the Continental Simos 19.6 ECU, which must be unlocked before it can be tuned. Using our supported OBD method, the ECU was unlocked, backed up and Stage 1 tuned through the diagnostic port in a single visit, with no ECU removal or mail-in.

What was included

  • Simos 19.6 OBD ECU unlock
  • Stage 1 ECU calibration
  • Speed limiter solution
  • Original ECU file backed up
  • Dealer-level diagnostics before and after
