As of 8/8/2025:

Most 2017 year models and early 2018s are not successfully unlocking but will flash once unlocked with HPT or Power Programmer. 

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 HPT unlock box. This will cost credits to unlock and AMDP will not be covering that cost.

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

Shift on the fly will be coming shortly.

Cab and Chassis are supported

This product is not for Kodiak/International L5D trucks.

Can-Bus plugs are still required.

We will be sharing a dash message reset file that has instructions for it's use if you have a dash message after tuning.

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
