As of 5/27/2025:

Most 2017 year models and early 2018s are not successfully unlocking but will flash once unlocked with HPT or Power Programmer. EZ is rolling out updates every couple of days so expect something to change soon.

EZ will allow you to send in the ECM to them for the ECM to bench unlocked where it will accept the EZlynk files.

But if you want to unlock any 17 or 18 trucks on-site you will need to use a power programmer or HP Tuners unlock box.

For the moment, this product will be single power files only.

Shift on the fly will be coming soon.

Cab and Chassis are supported

This product is not for Kodiak/International L5D trucks.

Can-Bus plugs are still required.

Modifications such as: FASS, CP3, different turbo options will need to be built per truck, so email us if your truck fits one of these situations
