     The quickest MK6 Golf R record is a highly contended title. As the decade-old engine and ECU combination reach the end of their production run, and newer more complex technologies are introduced, tuners around the world continue to tinker with bigger turbos, and new bolt-ons in a never-ending race to the bottom (pun intended).

     As of 11/7/2014, MK6 Golf R owner and Australia customer, Jared Bailey, proudly holds this title. To APR it’s refreshing and empowering when an independent customer takes an off-the-shelf kit and sets a new record. Most impressively, this particular car is still running the stock block and head, and does not use electronic/manual boost controllers, custom calibrations, WOT boxes, or water methanol injection; components commonly recommended or required by others to reach low 11, high 10 second quarter mile times in a MK6 Golf R.

     The record was broken at Calder Park drag strip, the record quarter mile times set with race fuel and pump fuel were 10.65@129mph and 11.06@124mph respectively.

     Still wide awake with excitement at the time this was article was written (around 4am Australian Eastern Daylight Time), Jared mentioned with a sly chuckle that he began modifying his MK6 Golf R in May 2014 “…when I went stage 2+. Things got out of hand since…”

     With such high ambient temperatures, he and APR are very confident he’ll break into the 10s on pump fuel, and are aiming for much lower times with race fuel when temperatures cool off.

     Dean Coutts from Fast Stuff, Jared’s local APR Dealer, must be proud to see one of his customers snag the title. Guy Harding, managing director of APR Australia couldn’t wait to share the bittersweet news. Bittersweet, because he and his team at Harding Performance/APR Australia had held this record for over 2 years. It was broken”…thankfully by one of our customers!” he joked.

     “Every day I grow more impressed by the support of our customers and the feats they accomplish with our products,” said APR CEO, Matt Young. “APR strives to provide the highest-quality, turn-key solutions for Volkswagen Group vehicles, and news like this reinforces that ethos.”

     The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware. With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 284 horsepower and with 334 ft-lbs of torque 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 57 horsepower and 85 ft-lbs of torque. By adding E85 to the tank on the Ethanol compatible variants, automatic Ethanol map blending adds even more power, resulting in 85 horsepower and 135 ft-lbs of torque. The increase in power directly translates to an exceptionally quicker and more enjoyable vehicle.

     By simply adding an APR downpipe exhaust system, APR's Stage II software, a free upgrade to existing APR Stage I customers, takes performance even further. on 93 AKI fuel peak figures of 302 horsepower and 334 ft-lbs of torque were achieved. Again, by adding E85 on flex fuel compatible variant, 318 horsepower and 405 ft-lbs of torque was achieved!

     APR’s ECU upgrade is the best power per dollar modification for the new 2.0 TFSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models, without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle.

 

APTuning is pleased to offer the latest transmission control unit (TCU) upgrade for the DQ250 Exx & Fxx DSG and S tronic transmissions! APR’s TCU upgrade is available in engine and power level specific variations and is conveniently flashed to the vehicle’s factory TCU through the OBD-II port. APR’s patented DirectPort Programming Suite allows the end user to customize the TCU upgrade to their individual needs.

APR’s TCU upgrade enhances the driving experience by incorporating many of the same features typically reserved for high-end Audi Quattro GmbH RS models. Under blistering, wide-open throttle acceleration, the transmission shifts even more quickly than before with a higher rev limit. However, during normal, day-to-day driving, the TCU Upgrade delivers a smooth, more refined, driving experience.

 

 

 

End User Adjustability

APR’s DirectPort programming suite allows users to custom tailor the TCU upgrade to their needs at the time of installation. Users are given the following options, which they may change at an APR dealer at any time:

  • User definable APR pre-optimized shift patterns based on current stage of engine performance
  • User definable launch control RPM
  • User definable manual mode max RPM
  • User definable manual mode automatic upshift on or off
  • User definable manual mode automatic downshift on or off (Kickdown switch)






Drive Mode Characteristics

Drive mode’s performance and comfort is greatly improved based upon the current stage of engine performance. Gear change upshift and downshift points occur based on engine load and throttle position, rather than hard set points, and as such occur more smoothly and less abruptly. The driver may feel more connected to the vehicle as the gear changes occur more naturally. Under part throttle driving, the transmission will stay in the current gear until the appropriate moment necessary to shift, rather than jumping to higher gears too quickly. This is especially true for calibrations geared towards larger turbocharger systems where response characteristics of the turbocharger changes the part throttle driving experience. Under wide-open throttle acceleration, shifting times are reduced and the maximum shift point RPM is set to the ECU’s rev limiter.




Sport Mode Characteristics

Sport mode’s performance and comfort is also greatly improved based upon the current stage of engine performance. Expect extremely fast gear changes as the wide-open throttle shift times are reduced. APR’s taken a two-stage approach to wide-open throttle operation as well. Shift points are optimized to deliver the fastest acceleration possible under wide-open throttle by following the torque curve of each available stage. However, with the pedal pressed far enough to hold the kickdown switch, shifts points override the torque curve and now occur at the maximum engine RPM!

Part-throttle drivability is greatly improved too. Some factory DQ250 transmission software is too aggressively geared towards holding high RPMs, and often uncomfortably downshifts when unwanted. Under low accelerator pedal position, low load driving, gearshifts occur earlier, allowing the driver to enjoy sport mode even during those moments when wide-open throttle operation is not permissible. However, should the driver request more torque with his or her right foot, the transmission comes alive in the true spirit of sport mode!




Manual Mode Characteristics

At the time of installation, the user is able to select several options that change the behavior of manual mode. The user has the ability to enable or disable either the manual mode automatic kickdown switch for automatic downshifts as well as the automatic upshift that occurs at redline. For safety and acceleration, APR’s engineers kept the automatic upshift present in first gear.

The ECU defines the maximum engine RPM possible. Using APR’s user definable max RPM settings, the end user can match the ECU’s RPM to the TCU RPM to avoid hitting the engine rev limiter should the automatic redline upshift option remain active. In the case where an APR ECU Upgrade's redline is lower than expected, APR can issue a free ECU update to correct the max engine RPM.

During manual mode shifting times are not only greatly improved, but the artificial delays between requesting a shift with the paddles and shifter are reduced as well. As soon as a shift request is made, the transmission instantly begins the shifting routine. Furthermore, the downshift lockout is removed, allowing the operator to downshift at any point, so long as the next gear does not surpass the max engine RPM.

With manual mode tailored to the end users need, they are presented with a more enjoyable driving experience that operates exactly how they choose. We call it Performance Without Compromise!




Launch Control

APR’s TCU upgrade enables launch control on all vehicles. At the time of installation, the user is able to select their desired launch RPM, as they see fit! Launch control activates quickly, with a wider operating window, by limiting some of the stubborn activation criteria some models face during activation. The end user will notice launches now occur more rapidly with less delay between releasing the brake and forward momentum. The clutches fully grab quickly off the line and shift times are reduced. This directly translates into faster acceleration!


Gear display indicator

APR’s TCU upgrade enables the gear display indicator for Drive and Sport mode in the vehicle's multi function display.


Torque Limits

All too often TCU upgrades are sold as a solution to “torque limiters” in which many companies charge extra to raise. While some companies may have trouble with torque interventions from the transmission, even at stage I power and torque levels, APR ECU upgrades do not require a TCU upgrade to meet advertised peak torque levels. APR does not charge extra to “raise the limits.” Raising the limits does not increase performance and does not increase the transmission’s ability to hold more torque. The maximum torque limiters are simply removed, allowing customers unrestricted operation. In the event torque is limited by the factory clutches, upgraded units may be installed and torque may be increased without TCU intervention.



DSG Temperature Management

Temperature management is an important part of the DQ250 transmission. While some software may simply remove temperature protection routines all together and claim increased cooling performance, APR’s TCU upgrade only allows the maximum safe temperature levels before intervention. Unlike the factory intervention routine, which simply allows for nearly no torque to be transmitted through the transmission at all, APR’s over temp intervention allows for a very limited amount of torque, enough so the vehicle can be safely driven off the track or pulled to the side of the road. In keeping the vehicle moving, airflow continues across the radiator, which in turn keeps coolant temps low and aids in removing heat from the factory DQ250 water to oil cooler to restore full operation.
