Diesel tuning of new trucks (2020 and newer) is getting to be a tough proposition. Truck manufacturers are making it nearly impossible to go into an ECM and manipulate the controller to help deliver more power and torque. Luckily, companies like Edge Products have not stopped working on this issue, and that means L5P Duramax diesel owners can benefit.

The latest from Edge is L5P Duramax diesel tuning with the industry’s first in-vehicle ECM unlock that includes transmission tuning for the new 10-speed. Now, you can easily flash your 2020 through 2023 L5P Duramax diesel with the all-new EvoHT2 programmer, without removing the ECM for unlock.

Edge’s Locksmith device and unlock cables work with the EvoHT2 and now offers complete ECM/TCM unlocking without touching the ECM. No dealing with sending in your ECM for tuning or as a core. No finicky ECM harnesses to disconnect and no ECM swap is required.

This is a complete plug-and-play flash tuning solution for 2020 through 2023 GM L5P Duramax diesel owners. The big news here for 2020-plus owners is the addition of TCM support for optimal transmission performance from your 10-speed Allison. The tuning offers improved shift points, as well as better clutch holding capacity from better line pressure and converter lock-up. Help your 10-speed handle everything you can throw at it whether daily driving or towing.

The EvoHT2 is a great tuning option with a simple and easy-to-use interface, a color screen with great visuals, and four pre-loaded tunes to meet every owner’s specific needs. EvoHT2 offers it all. This all-new process completely changes everything you once knew about tuning your L5P diesel. The EvoHT2 offers power gains (as much as 125 horsepower and 275 lb-ft of torque to the tires) with improved throttle response, quicker turbo spool-up, better fuel economy, and total control over your driving experience.

Enable the ‘Remember Last Setting’ feature that allows your truck to remember your drive modes like Tow/Haul, Grade Braking, and Exhaust Brake settings every time you start your truck. At less than half the cost of many ECM flash options, EvoHT2 for L5P diesel gives you everything you need.

Unlock your L5P’s max potential with Edge flash tuning, a PC and Edge’s downloadable Update Agent software will be required to complete the tune process One device can unlock and tune only one vehicle. Once the ECM/TCM is unlocked and flashed, the truck can be returned to factory settings, but the Unlock process cannot be reversed. If a VIN lock and ECM unlock have been completed, the device is non-returnable.
