For diesel truck enthusiasts looking to maximize performance and monitoring capabilities, combining an Edge CTS monitor with a CSP5 tuning switch is a popular setup. Ensuring these devices work harmoniously often comes down to the correct OBD2 cable configuration. One user from the Cummins forum shared their successful experience, highlighting a specific setup that eliminates potential connectivity issues.
This user employs a “pass-through” or “double-sided” CSP5 cable in their configuration. This setup means the OBD2 sequence flows from the truck’s OBD port, then through the CSP5 OBD connection, and finally to the Edge CTS OBD cable. This clever arrangement allows both the CSP5 tuning and the Edge CTS monitor to remain connected simultaneously, providing real-time data and on-the-fly tuning adjustments without the need for constant plugging and unplugging. To secure these connections, the user mentions using a zip tie to keep the plugs firmly in place, ensuring uninterrupted data flow, though this isn’t visible in the provided images.

For critical measurements like Boost PSI, Oil Pressure PSI, and Exhaust Gas Temperatures (EGTs), the user utilizes Edge Accessory System (EAS) accessories. While acknowledging that acquiring a complete EAS setup can be an investment, they emphasize its user-friendliness, clean integration, and simplicity. Specifically, they employ two EAS kits: the Universal Sensor Input (98605) for Boost and Oil Pressure. It’s important to note that boost sensors require a “dry” sensor, while oil pressure sensors need a “wet” capable sensor. These sensors wire into the EAS kit and are configured via computer before reconnecting the CTS to the truck. A similar process is used for the EGT probe. The user recommends the “EAS starter kit w/ EGT probe” (98603) as it includes the necessary module for linking these accessories to the Edge system in a daisy-chain configuration. This setup has proven reliable for the user over 1.5 years.

Regarding CSP5 programming directly through the Edge CTS, the user believes it is not possible, based on their last understanding. It’s always advisable to verify the latest compatibility information from Edge and CSP5 manufacturers as features can change.
In conclusion, this user’s experience provides a valuable insight into successfully connecting an Edge CTS monitor and a CSP5 tuning system using a specific OBD2 cable configuration. By utilizing a pass-through CSP5 cable and EAS accessories for enhanced parameter monitoring, diesel truck owners can achieve a comprehensive and user-friendly performance monitoring and tuning setup. While direct CSP5 control via Edge CTS may not be available, this configuration offers a robust solution for many enthusiasts.
