The new update brings several enhancements and improvements to our existing Stage I and Stage II ECU Upgrades. The upgrade address all reported issues with previous versions and adds several new torque levels to address concerns with slipping DSG / S Tronic and 6MT transmissions. Stage I is now offered with high and low torque variants, while Stage II is offered with high, medium and low torque variants. Each Stage’s High Output levels are offered with even more horsepower and torque than before! Please visit our product page for detailed power levels, requirements and more.
This update is offered for free to existing North American APR ECU Upgrade customers at all APR dealers and is currently available for all ECU box codes and revisions associated with the new North American Golf R and S3! Contact an APR dealer today to get updated!

- New Stage 1
- Higher power / torque - figures on website.
- Requires stock DP.
- Compatible with other bolt-on modifications.
- New High and Low Torque stages.
- High Torque.
- May require v2.1.1 (or higher)
DSG / S Tronic software or 6MT clutch
to prevent slip on a healthy
transmission.
- Low Torque.
- Designed for healthy, unmodified
DSG / S Tronic and 6MT transmission.
- 91 Octane software provides
the lowest torque.
- Available for 91 AKI, 93 AKI and 100 AKI fuel.

Fixes:
- Addressed all known fault codes, CEL and EPC reports
(Camshaft position, DBW throttle monitoring, etc).
- Calibration improved to prevent reaching fueling system
limits (Mismatched ECU Stage vs Hardware Stage).
- Fixed condition where Motorsport Limiter would limit
torque after a gear change.
- Motorsport limiter now allows boost to be maintained
with no throttle closure while active.
- Minimized condition where DV would not close after a full
throttle shift on manual cars (Factory issue).
- Audible part-throttle "sound" greatly reduced. May
still be noticeable with an intake.
- Improved throttle response at low RPM during
initial take off.
- Fixed boost oscillation at low RPM in high gears.
