  - 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.

APR 1.8 TSI Generation 3 ECU Upgrade for the MQB Platform

Posted on December 16, 2014 – 8:00 am

Achtuning is excited to announce the re-release of APR’s ultimate engine control unit (ECU) upgrade for the Generation 3, 1.8 TSI and TFSI engine as found in the MQB platform vehicles. APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

The ECU’s Continental SIMOS 12.x engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to help ensure an enjoyable driving experience.

APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world!

APR’s ECU upgrades are one of the best horsepower-per-dollar modifications for the new 1.8T engine. 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 298 ft-lbs of torque and 251 horsepower with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 97 ft-lbs of torque and 81 horsepower.

APR Stage II ECU Upgrade is designed to work with APR’s upcoming Exhaust Downpipe and is a free upgrade for APR Stage I customers. When combined with APR’s Intake System, peak power and torque figures grew further to 256 horsepower and 304 ft-lbs of torque. While peak power did not increase by much, the additional hardware allowed the turbo to spool faster and power carried better towards redline, resulting in up to 16 horsepower more.

The increase in power directly translates to an exceptionally quicker vehicle. Using advanced GPS measuring devices, APR’s engineers conducted several acceleration tests. During the 0-125 mph sprint, the APR Stage I equipped vehicle finished 22.048 seconds sooner that stock and the APR Stage II equipped vehicle was an addiitonal 3.112 seconds earlier!

The results were astounding. By simply adding the APR Stage I ECU upgrade, the 2015 Golf Tiptronic test vehicle completed every test quicker than the stock vehicle by a large margin and even bested our own stock MK7 GTI DSG results with ease. 0-60 MPH times were reduced by 1.101 seconds while the 62-124 MPH occurred in less than half the stock vehicle’s time at 16.758 seconds or 19.9 seconds sooner! Acceleration tests were conducted all the way to 125 MPH, which was completed in 23.637 seconds with APR stage 1 software and 45.685 seconds with the stock software.

Utilizing APR’s Stage II software with the APR Intake System and APR Downpipe, the gap between stock and modified grew even further. Once again, the APR Stage II equipped Golf was faster in every test, and showed excellent improvements over the APR Stage I equipped vehicle. Most noteworthy was the 0-125 MPH sprint, which was completed 25.161 seconds faster than stock. At the standard US bus length of 45 feet, the APR Stage II equipped vehicle finished the 0-125 MPH test with the stock vehicle an astonishing 8.55 bus lengths behind! Even more impressive was the fact this test was completed in under a half mile (.464 miles), while the stock vehicle needed 1.2 miles of runway to complete the test!

No appointment is necessary for you to receive this upgrade in your Gen 3 MQB 1.8T – just roll through between the hours of 9am and 4pm, Monday through Friday and we’ll have you in and out of here in less than an hour!
