The EDGE Insight+ CTS3 Monitor & Custom Tuning Device for the 2017-2019 GM 6.6L Duramax L5P is the ultimate performance and monitoring solution for your truck, delivering all the functionality of the industry leading Insight CTS3 with the added capability of custom tuning.

This kit is built specific for 2017-2019 GM L5P Duramax applications and includes all required hardware to be able to monitor and unlock/flash ECM third party calibrations into the truck. Kit includes our revolutionary Locksmith unlock tool, ECM unlock harness, and our cast A-pillar mount for an OEM like fit of the Insight+ monitor in the cab. Whether you’re looking to keep a close eye on vital engine parameters or load custom tunes for optimal power and efficiency, the Insight-Plus has you covered. Pre-loaded with a custom tune license, this device allows you to read your truck’s ECM and create a backup file that can be sent to your preferred Edge approved custom calibration shop. Once your tuner customizes the files for your truck, you can easily upload them via your PC and flash them to your vehicle in just a few simple steps, this tuner is built to grow with your needs.

Beyond tuning, the Insight+ provides real-time monitoring of key vehicle parameters like EGT, regen cycles, transmission temperature, boost, RPM, and more, all displayed on a crisp, easy-to-navigate touchscreen. Swipe between customizable layouts for towing, performance, and economy, or take advantage of built-in performance meters to track 0-60 and quarter-mile times. An advanced data logger lets you export driving data, while integrated diagnostics allow you to read and clear DTC codes with ease. Installation is simple, just plug it into the OBDII port, no wiring required. The Insight+ also features Wi-Fi updateability, manual and mobile DPF regeneration capabilities for select diesel applications, and compatibility with Edge’s EAS (Expandable Accessory System) for adding sensors to monitor even more parameters. For those who like to keep things clean and factory looking cabins, it can also control 12V accessories like auxiliary lighting directly through the touchscreen, eliminating the need for extra switches cluttering your dash.

Sleek, powerful, and packed with features, the EDGE Insight+ CTS3 is more than just a digital gauge, it’s your key to unlocking your truck’s full potential while keeping it running safe and strong. Whether you're a daily driver, a heavy hauler, or an enthusiast pushing the limits, this is the performance tool you’ve been waiting for.

Works as intended
Size: 12 Pairs / 24 pcs
These banana plugs are quite easy to use, and securely connected my speaker cables to the receiver. They have a quality feel as well.

Tips broke in the binding post
Size: 12 Pairs / 24 pcs, Size: 12 Pairs / 24 pcs
UPDATE: Two tips broke off when unplugging them from the binding post and are now lodged in. Inexcusable and an utterly poor product. Solid connection in the binding post with no wobble or wiggle. They require some force to insert into the binding post, but once they're in they remain snug. I also tried removing and reinserting a few times and the connection remained solid. I've used other plugs in the past that have a softer tip and easily deform after one or two insertions. These do not have that issue.

Does the job, easy use, a bit bulky not exactly as described
Size: 12 Pairs / 24 pcs
Bare wire can be intolerable to work with. Banana plugs make a positive secure connection. These plugs are a touch bulky. Nice to not have to deal with small screws. Use as large of gauge wire as possible. The description says no unintentional disconnections. I beg to differ the bite of teeth aren’t as good as described. Used a 16 gauge pure copper speaker wire and a teenager taught me how secure the wire really is by tugging on the wire not the banana plug pulling the wire free. It does the job, it’s not the latest and greatest. If you need easy get these. If you want slim secure banana plugs buy the small screw type.
