The EZ Lynk is the best tuning platform on the market. Most of the major tuners now offer it as an option. If we can help answer any questions please let me know.

Anybody have issues with turbo surging/excessive cycling? When I'm cruising at a constant throttle input and maintaining speeds, my VGT will cycle back and forth from holding ~10 psi boost down to 3ish then back up. VGT command seems to fluctuate up and down. Rail pressure holds steady when this happens.

So I'm close to pulling the trigger on EZ LYNK with PPEI. I wont be deleting right away. My question is, will this setup allow me to clear the dreaded "diesel exhaust fluid poor quality" fault. I've been in limp mode before and I don't want to go back.

I will delete eventually, but will this keep me out of trouble till then?

I would disagree with the previous statement. If you load a deleted tune on a non deleted truck, my understanding is, you will be in a not so good place. I’m fairly certain the dpf must be removed. Now ez lynk does have emissions intact tuning, but I don’t see how that would remove the code.

I wasn't even planning on loading a tune. Is that what you do to clear a fault? The website says:

The EZ LYNK AutoAgent will support the following vehicles for custom tuning:
•GM: 2011 – 2016 6.6L Duramax
•ECM Tuning
•Read & Clear Diagnostics Trouble Codes
•Record Live Data & Playback Data Logs
•Apple iOS & Android Smartphone support
•Cloud Based Tuning Platform

My primary need is to clear faults/ codes associated with DEF / emission problems. Man, this is hard to wrap my head around.

If all you want to do is delete the code, then yes. It will work. But, if there is a problem. It will just come back. Deleting a code doesn’t delete the problem.

There are far less expensive ways to just delete CEL code. Any obd II reader will do that.
