EFI Live, EZ Lynk, or MM3 Tuner Info - Which is better and Why?

**DRD** · 06-19-2017

Howdy folks! I'd thought it would be great to create a thread to help the newcomer decide which tuning device for the 6.7 Cummins powered Ram Pickup is best.

I want this to be an open and honest thread. I want facts and your opinions. I want this to fair and balanced. I do not want any bickering and arguing. I want this to be helpful for the newbies out there coming into the diesel performance market.

You may ask, why did I create this thread as an MM3 dealer only? You may say surely he's gonna be totally biased...well NOPE. The answer is there are a lot of lies, misinformation, and covering up of the truth out there in internet land...and I'm sick of it!! Unfortunately, so many newbies are hitting social media groups like the Facebook group 6.7 Cummins Performance and only seeing part of the truth. I've been involved with that one myself and mention some truthful things only to see it disappear. And unfortunately, the newbie only gets to see the part the ones in charge want them to see. Well...that won't happen here!

OK, having said all that I'll give you my opinion...sort of.

I think in the hands of a capable tuner they are all good options. Hardware wise they are different and the consumer may like one or the other just based on that simple fact...but WHOA, the hardware isn't any better than the ones writing the tunes and the ones providing customer service for them! That's the bottom line in my opinion!

Look at it like this, you can take a pile of dung and put it in a shiny box...but it's still crap. Likewise with tuners. One shop can offer the coolest looking gadget out there, but if the tunes and service suck...it's just crap.

OK, let the discussion begin! Tell us which one you like and Why. Keep in mind someone new may come along and read this...and this just may be the deciding factor in their purchase!

Great idea for a thread Ray, I know I did a ton of research before I picked the MM3. I don't know a ton about the ezlynk but the few reasons I chose the mm3 over efi was because I liked the simplicity of changing files with your tuner. Ray is down in North Carolina and I'm waaaay up in Canada. If I need something tweaked or changed he's just an email away. From what I understood about the efi platform was you needed to send the autocal back to your tuner to re-flash it with your updated tune and then send it back to you to flash your truck. If you plan on slowly adding more performance mods like I do I can easily get my tunes updated through email. In terms of hardware, I like the look of the mm3 display. If I was to go the efi route you need the bullydog (which is one ugly display if you ask me) to unlock the truck, an autocal to flash your tunes, and I would have wanted an edge juice with attitude as my display. That's a lot of hardware when the mm3 covered all three things with one piece of hardware. The third reason I chose the mm3 was the RT function. You can store more than the 5 tunes efi would do with a CSP5 switch on your dash and you don't need the switch it's all right on your display. With data logging out now for the mm3 it makes sending your tuner (who lives a long way away) a spread sheet of how your trucks performing to help tweak tunes for you. That's why I would go with the mm3, in my option it's the best option out there right now. Unfortunately not many people know about it but when I show people my truck it defiantly blows them away what I can do with that tuner. 🤙

You still can update EFI though email. You even if your not the tuner can upload them to you auto cal no problem.

Nice to know MM3 has data logging.

With all 3 platforms, tune files are just always just an internet connection away. With the MM3 and EFI we merely email tune files. With Ezlynk, tune files are sent via their cloud server.

Same goes with data logging with all 3.

This is my problem with the EZ Lynk. My background is in IT & Cybersecurity and I currently work for a global backbone network provider & every time I see this I want to cringe. The main reason being that I cannot find any mention of security measures for the AutoAgent cloud. You need to remember that all the cloud is, is someone else's computer. My concern is that a vulnerability in the AutoAgent cloud could give a threat actor a direct line of communication with your vehicle.

Let's not forget the fact that a team of professional hackers already was able to hack into a Jeep Grand Cherokee, while it was driving on the highway, and take over full control of the vehicle. Adding a 3rd party Cloud based connection device into your CANBUS system seems like asking for someone to get into your electronics. I don't doubt that EZ Lynk has developed security protocols to secure the connection between the cloud and the device, but it seems risky nonetheless.

Bingo!

You'd don't want to know what we heard about them.
