Drive (eco) and Sport Mode:
APR’s calibration experts found the factory drive and sport modes to be less than ideal when raising power above the factory limits. In drive mode, the transmission aggressively seeks sixth gear, earlier than necessary, leaving behind an anemic and lack luster experience for the driver. Likewise sport mode leaves a lot to be desired considering its seemingly exciting name. Under both modes, maximum shift points remain optimized for the factory power levels, which vary greatly to those produced using APR’s world-renowned catalog of performance hardware and software. As such, accelerative performance suffers due to non-optimized shift points.
To rectify this situation, APR’s engineers took a multi-step approach to custom tailoring the shift maps to sync harmoniously with APR’s performance upgrades and each platform’s gear-ratio configurations. While some may simply set wide-open-throttle, or WOT shift points to the vehicle’s max RPM limit, APR’s engineers chose shift points based on actual acceleration data. This result is gear dependent shift points typically below the engine’s max speed, but in doing so, the vehicle’s acceleration improves as axle torque is matched before and after shifts.
Under low-torque, low-rpm, part-throttle situations, both modes less aggressively seek the highest possible gear. Drive still has the benefit of economy, but stays within the power band more comfortably for a more enjoyable experience. Likewise sport mode has been optimized to provide a sporty feeling, worthy of its name. In both cases, the transmission seamlessly integrates with APR’s performance upgrades to provide an exciting driving experience.
Manual and Tiptronic Modes
APR’s user definable options allow the end user to configure how the transmission works while the gear selector is placed in manual mode.
The kick-down switch, which is responsible for an instant downshift, is enabled by default but can be disabled at the time of install. Likewise the auto upshift that occurs at the vehicle’s maximum engine speed can also be disabled at the time of install, allowing the engine to bounce off the limiter like a manual transmission.
The transmission does not lock out any manual downshifts so long as the shifting does not result in an engine RPM above the max shift point. In all situations, paddle delay is reduced, allowing for a more responsive shift to take place and furthermore, shift times have been optimized.
