New APR ECUs (v2.3) and TCUs (v2.1.1) – Up to 387 HP / 409 FT-LBS of Torque!

Posted on March 24, 2016 – 9:00 am

Today is a good day for the new MQB platform with two new updates!

Version 2.3 is Now Available for the North American MK7 Golf R and S3

APR is pleased to announce free updates to our existing North American MK7 Golf R and S3 ECU Upgrades! The new update brings several enhancements and improvements to APR’s existing Stage I and Stage II ECU Upgrades. The upgrade addresses 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!

This update is offered for free to existing APR TCU Upgrade customers at Achtuning, with only an installation cost of $52.50 + tax.  No appointment necessary!  Stop by between 9am and 4pm, Monday through Friday.

V1.0 to V2.3 Change Log
New Features:
  - Motorsport Rev limiter
  - 6MT standing  2-step limiter @ 4000 with boost building.
  - DSG standing limiter @ 5000 for free revving.
  - New Stage 1
    - Higher power / torque - figures on website. 
    - Requires stock downpipe. 
    - 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. 
  - New Stage 2.
    - Higher power / torque - figures on website. 
    - Requires a high flow downpipe. 
    - Intake recommended to meet advertised power levels.
    - Compatible with other bolt-on modifications.
    - New High, Medium and Low Torque Stages.
      - High Torque.
        - Requires an intercooler to meet advertised power levels.
        - Requires v2.1.1 (or higher) DSG / S Tronic software.
         - Most likely requires a 6MT clutch to prevent slip on a healthy transmission.
      - Medium 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.
        - Available for 91 AKI and 93 AKI fuel with MBT achieved on 93 AKI. 
 
Fixes:
  - Addresses 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.

APR is also pleased to announce a free update to their existing MQB platform TCU Upgrades! Version 2.1.1 is now available for the new GTI, Golf R, A3, S3 and more and offers several enhancements and improvements over APR’s previously released versions. The new version brings increased clamping pressure to all vehicles at all stages, allowing the transmission to hold more torque without slipping. Launch control is improved with new torque management strategies, resulting in more consistent launches, faster torque onset, and varying torque ramp rates to help minimize wheel spin and short 1 -> 2 shifts. Based on customer feedback, part throttle shift maps were updated to prevent the transmission from racing to 6th gear, or toggling back and forth between 5th and 6th during cruising. Finally, also based on customer feedback, R/S3 platform vehicle’s 1 -> 2 part throttle shift map were adjusted to hold first gear longer.

This update is offered for free to existing APR TCU Upgrade customers at Achtuning, with only an installation cost of $52.50 + tax.  No appointment necessary!  Stop by between 9am and 4pm, Monday through Friday.

Change Log
- Increased clamping pressure past factory limits  on all vehicles / stages.
- LC enabled with ESP enabled or disabled.
- Faster torque onset after launch.
- Torque ramp rate adjusted to minimize wheel  spin and short 1 -> 2 shift.
- More consistent launches with torque management. 
- V2.0.1 - adjusted part throttle shift maps to  prevent racing to 6th (based on customer feedback).
- V2.0.1 - adjusted 5 / 6 shift maps to prevent toggling back and forth during cruising (based on customer feedback).
- V2.1.1 - adjusted 1 -> 2 part throttle shift map [R/S3 gearing] (based on customer feedback).
