| 3 | ## 1 Purpose |
||
| 4 | |||
| 5 | This page captures the **mandatory hardware and signal‑level requirements** for the upcoming firmware/software release of the Firmware. It serves as a reference for testers, installers and customers to verify that their hardware stack and wiring meet the minimum specifications before flashing the new version. |
||
| 6 | |||
| 7 | ## 2 Hardware Prerequisites |
||
| 8 | |||
| 9 | * **Gearbox Control Unit (GCU):** Devices with serial numbers GCU2202001 and up require a hardware upgrade to address some of the manufacturing isues *(Mandatory)* |
||
| 10 | * **Signal‑conditioner board:** Required only when interfacing with **DCT GS7D36SG** speed sensors. *(Mandatory for DCT GS7D36SG installations)* |
||
| 11 | |||
| 12 | |||
| 13 | ## 3 Required Signal Inputs |
||
| 14 | |||
| 15 | | Signal | Source | Connection Method | Notes | |
||
| 16 | | ----------------------------------------------- | ----------------------------------- | ------------------------------------- | ------------------------------------- | |
||
| 17 | | **Brake‑pedal position** | Hydraulic switch or position sensor | Analog IN **or** CAN | On/Off signal | |
||
| 18 | | **Engine RPM** | Crank/Cam sensor or ECU | Frequency IN **or** CAN | | |
||
| 19 | | **Throttle position (TPS)** | ECU / DBW | Analog IN **or** CAN | | |
||
| 20 | | **Accelerator pedal position sensor (PPS)** | ECU | Analog IN **or** CAN | | |
||
| 21 | | **MAP sensor** | ECU | Analog IN **or** CAN | kPa | |
||
| 22 | | **Injector pulse width** *or* **Engine torque** | ECU | Frequency IN (PW) **or** CAN (torque) | Provide either PW (µs) or torque (Nm) | |
||
| 23 | |||
| 24 | |||
| 25 | ## 4 DCT GS7D36SG‑Specific Requirements |
||
| 26 | |||
| 27 | * Install the **signal‑conditioner board** between the gearbox speed sensors and the GCU. |
||
| 28 | |||
