Automatic Transmission V2.0
DESCRIPTION

Changes & Fixes in V2.0: 

Added "Sport" & "Race" shift pattern / logic presets.

Added 2-stage kickdown algorithm.

More realistic CVT gear ratio control algorithm.

CVT now has an option to define gear ratio range apart from manual mode.

Improved shift algorithm for better acceleration & fuel economy.

Improved intake pressure estimation for VVT / VTEC equipped engines.

Improved power units torque calculation.

Improved torque converter K factor / clutch force estimation.

Improved downshift blipping algorithm.

Improved CVT step control / torque limits calculation.

"Next Gear" & "Previous Gear" no longer act as paddle shifters when the car is stationary with brakes applied.

Extra option G / H / I / J now in-sync with the script. (for custom shift animations.)

Fixed an error triggering auto upshift in true manual mode.

Fixed unexpected behaviors with different shift pattern / input configuration combo.

Toggling replay mode no longer resets the transmission.

Features:

Physics Simulation of Automatic Transmission

Improved Throttle Response

Automatic Physics Calculation & Adaption for Different Car / Setup

Shifting Algorithm Based on Real Cars

Realistic Gear Display in Car Instruments & Vanilla Apps

Transmission Presets (AT, CVT, DCT)

Shift Pattern / Logic Presets (Eco, Manual, Sport, Race)

Multi Shift Inputs Support & Simulation

AI Car Support (without clutch control)

KsACD (data.acd) Support

Known Issue:

Not working for online.

HOW TO (Latest Custom Shaders Patch required)

1. Extract the data.acd of the car you want to use through Content Manager or KunosSDK

2. Open car.ini in data folder and edit it to match the values below.

[HEADER]

VERSION=extended-2

3. Open drivetrain.ini in data folder and edit it to match the values below.

[GEARBOX]

VALID_SHIFT_RPM_WINDOW=100000

CONTROLS_WINDOW_GAIN=1

[AUTOCLUTCH]

FORCED_ON=0

[AUTOBLIP]

ELECTRONIC=0

4. Add below lines and edit it to match the spec of the car.

[AUTO_SHIFTER]

TRANSMISSION=0 ;0 = AT, 1 = CVT, 2 = DCT

LOGIC=0 ;0 = Eco, 1 = Manual, 2 = Sport, 3 = Race

4.# It's now possible to define custom CVT gear ratio range for "D" mode.

[GEARS]

RATIO_MAX=2.526

RATIO_MIN=0.408

4.## Read description below to better understand different logics.

M Gear definitions are reversed between "Manual" and "Sport" logic when transmission is set to "CVT".

Shift Pattern / Logic: Eco

Sport Mode: N/A

Paddle Shifter: N/A

M Gear: OPTIONAL (available to transmission with 6 physical forward gears or more, in reversed order.

True Manual Mode: N/A

Temporal Manual Mode: N/A

Shift Pattern / Logic: Manual 

Sport Mode: YES

Paddle Shifter: YES

M Gear: YES (in reversed order.)

True Manual Mode: YES

Temporal Manual Mode: YES

(Press either paddles in "D" or "S" gear to activate temporal manual mode, hold "Paddle Shift Up" or cruising for a while to deactivate.)

Shift Pattern / Logic: Sport 

Sport Mode: YES (combined with M gear.)

Paddle Shifter: YES

M Gear: YES (operated in M/S mode.)

True Manual Mode: YES

(press either paddles in "S" gear to activate, hold "Paddle Shift Up" to deactivate.)

Temporal Manual Mode: YES

(press either paddles in "D" gear to activate, hold "Paddle Shift Up" or cruising for a while to deactivate.)

Shift Pattern / Logic: Race

Sport Mode: YES

Paddle Shifter: YES

M Gear: YES

(served as a switch, can be triggered by paddle shifters or "Next Gear".)

True Manual Mode: YES

(hold "Paddle Shift Up" or press / hold " Next Gear" to deactivate.)

Temporal Manual Mode: No

5. Extract downloaded file into the data folder.

6. Check Use unpacked data if exist at CM's Drive Page with exact same car selected. (Or recompile data folder to data.acd.)

7. Make sure Automatic shifting, Automatic clutch & Autoblip are disabled in CM's driving assist menu.

8. Map the inputs listed below, if you don’t have spare buttons for these inputs, they can still be activated by pressing or holding the Next gear / Previous gear buttons.

Available in Forward Gears

Extra option G = "Paddle Shift Up" (Default: Press "Next gear".)

Extra option H = "Paddle Shift Down" (Default: Press "Previous gear "while the car is moving.)

Extra option I = "Gear M". (Default: Hold "Next gear".)

Global Switch

Extra option J = "Sport Mode or O/D Switch". (Default: Hold "Previous gear".)
