For those of you who don’t know about our current Sport Enhanced mode, it is an available feature with our B-Spec Tune where we remap your throttle response to become more linear and responsive to the driver. While the current mapping is already very responsive, we thought that it could be refined a little further and it’s safe to say we achieved that. As a result, we are happy to introduce our new and improved sport throttle mapping: Sport Plus Mode.
This change may be difficult to notice, but compared to the previous Sport Enhanced Mode, pickup and acceleration from cruising speeds are much more responsive than before. There are three main characteristics of Sport Plus mode that differ from the previous Sport Enhanced: Torque Load Management, Electronic Throttle Duty Cycle Curve, and the WOT Threshold.
Improved Torque Load Management
A significant amount of torque load management system was flattened out in order to allow the car to feed in more power during heavy acceleration. This is to avoid the engine from being heavily filtered by the ECU’s torque management system. Additionally, the torque reduction becomes more linear as a result of the newly flattened curve.
Revised Electronic Throttle Duty Cycle Curve
We also modified the curve of the electronic throttle duty cycle in order to smooth out initial acceleration from lower RPMs. SMG drivers should notice more of a difference as this remapping should smooth out a lot of the jerkiness associated when accelerating out of a standstill.
Lowered WOT Threshold
We also lowered the threshold throttle values for the car to switch to WOT open loop map. This means that the car will switch to a WOT mode a lot sooner, which increases the perception of the engine’s instantaneous responsiveness.
Please note that the changes on Sport Plus Mode will not affect power gains or dyno curves. This feature release focuses solely on throttle response, acceleration and drivability of the car. This feature will replace the original Sport Enhanced mode, and be referred to as our Version 2.1. This is as a free revision to our existing customers for those who are wanting to update to Sport Plus.
