	The RaceCapture app allows users to map custom OBDII PIDs according to their needs. ~~This~~ process involves several steps, identifying the PIDs using Torque App to configuring them within RaceCapture. Here's a simple guide to help you map your custom PIDs successfully.		The RaceCapture app allows users to map custom OBDII PIDs according to their needs. The custom OBDII PIDs (On-Board Diagnostics II Parameter IDs) are not part of the standard set of PIDs defined in the OBD-II specification and are used to extract detailed and specific data about certain parameter of the car. Extended PIDs provide a deeper level of access to vehicle data and are particularly useful for comprehensive diagnostics, performance tuning, or in-depth monitoring of vehicle systems.

			For mapping these extended PIDs, we can utilize the '''Torque App''', '''a separate and third-party application''', known for its comprehensive library of OEM-specific extended OBDII PIDs. The extended PID mapping process involves several steps, identifying the PIDs using Torque App to configuring them within RaceCapture. Here's a simple guide to help you map your custom PIDs successfully.

			'''Note:''' Precise conversion of Torque formulas to RaceCapture is crucial. Any errors here could lead to incorrect data being displayed, which might affect your diagnostics or performance measurements. Ensure each step is correctly followed for accurate data readings.
