Last Summer I took my 2018 (100% stock at the time) to Colorado and got up to about 13,000 feet for a couple of weeks and had no issues until I was about heading back down, at around 8-9000ft the check engine light came on. I pulled over and scanned it, 1 code (I do not remember the actual code, want to say MAP related) no other symptoms at the time just the CEL. Cleared it no other issues to date. Hadn't thought about it until I saw this post. Obviously there is a big difference between a few weeks at high altitude and being there constantly, I just thought I would share my experience.

 

deleted apologies

 

Thank you for the helpful information. With what did you scan it? Forscan?

 

Is that Minimax V2 a reliable tune? Totally safe for the engine? They don't turn off any safety controls do they?

 

There are some parameters you can set on the MM to defuel the engine. I don't recall all of them, but I remember having some.

 

Either Forscan or OBD Link, I use both.

 

Thank you for the hint!

 

so the issue I see is with the emissions in tact, it is made for low suffer diesel. Any diesel fuel mexico and south is high sulpher diesel and will cause problems.

 

Why is "high" sulfur fuel prone to cause problems? Is it due to the after treatment, or something else? Sulfur is among other things a lubricant for the fuel system at least for pre-emission diesel fuel systems.

What problems does "high" sulfur fuel cause in the ULSD designed systems of newer engines?

 

You brought up a good point... Plus the fact of how much DEF he'd have to have on board, store or to possibly buy... Not happening in Mexico and South of there I wouldn't think...

I hadn't posted again but was thinking he'd be best to delete with a stock power tune, test run it in Germany to check/solve any issues that arise...

EDIT... found this link about Diesel in Mexico. It's dated but it's a start for the OP...

From 2019...

This is more recent, from 2021... it appears Mexico keeps putting this off... a lot.

What's wild to me is that the Minimax V2 looks like a Bully Dog GT Tuner... EXACTLY the same.

Okay so there are known issues and this is for the OP because I don't know if he has seen this... from the product page.

Truck Model/Year and Errors

ALL VEHICLES: The Mini Maxx V2 does not support the factory pyrometer/EGT probes. Be sure to unplug all of them. If you need EGT readings you can add a docking station to the Mini Maxx.

2011+ Ford Powerstroke: 1) Tuners with older software may throw a P24C6 or P24DA PMS code. This does not mean you did anything incorrectly, there is an issue with our previous calibrations and specific PCMs. As of October 2023, this issue has been fixed. If you are getting either of these codes, update your device. 2) Certain PCM software doesn't get along with our SOTF strategy and will not change power modes, this is rare and affects roughly 7% of the 2011-2019 Fords.

​

2016 Ford Powerstroke: The 2016 model year does not contain a PCV sensor that the MMV2 looks for resulting in a CEL for code P04E3. We have completed the fix for this issue, if you have this code you will need to download the fix file from HERE, extract it and copy the "MGGDT.IT1" file into the "FORD" folder on the SD card, then update the firmware on the tuner and reinstall the tune. Only download this file if your truck has the code.

Since it mentions this>>> If you need EGT readings you can add a docking station to the Mini Maxx.

I wonder if these will work since the MiniMax looks like a Bully Dog GT tuner...

Thank you!
This is very, very helpful!

 

No problem... I found the universal docking station to work with the MM V2 here.

These look to be the same so I guess you can also add different sensors to it... here's a link to the Bully Dog docking station here. There looks to be more inputs there in front...

From there:

"The Bully Dog Sensor Docking Station is designed to be the best and easiest way to integrate additional sensors with your Bully Dog GT tuner or Watch Dog system to monitor the performance of your Cummins, Powerstroke, or Duramax-powered diesel truck. The Sensor Docking Station expands the monitoring capabilities of your truck to display a wealth of information at your fingertips.

This Bully Dog Docking Station includes one Pyrometer and can support a variety of aftermarket sensors to monitor the following information:

• Speed
• Air intake temperature
• Boost pressure
• Oil temperature
• Oil pressure
• Transmission temperature
• Exhaust gas temperature (EGT)"

 

@1ANZ what's your time frame on this? Do you have all the logistics figured out such as camper (I'm assuming you are doing an overland style truck with in bed camper), tires and size you're going to use because standard tires these trucks come with won't cut it, fuel storage on board, bigger replacement tank, truck supplies and fluids, spare tire, tools, etc... ?

Truthfully, looking at those articles on the fuel in Mexico, and I'm sure it gets no better in Central America and South America, deleting is the way to go that's one less fluid (DEF) you have carry or try to find down there.

 

The issue with the bullydog tuner is it can be buggy. for example, you may have to upload the new tune from the tuner the old fashioned way, download to your laptop with a program that can read the tune, and then upload it to the handheld tunerr. instead of just uploading it straight to the handheld tuner. Mine acted like this and it failed to load on the truck. the company helped me work around it right then and there so its ok. but ezlink is definitely the best way to go.

you can leave the EGR on and unplug it. It will fill with soot though. So going back to stock will mean having the EGR cleaned. removing it wasnt all that bad. just make sure you soak the exhaust bolts in your favorite flavor of rust penetrator the week or so before you start the work. especially when its nice and hot from being driven.

for that long of a drive i would HIGHLY recommend a flow thru muffler of some sort. nothing with any fiberglass packing, its gotta allow the soot to flow through and exit.

canada has great tuners, you should be able to find them via a simple google search. make sure you find a Proven Diesel tuner...

whatever handheld you go with will store the OEM tune. you should also save it to your computer.

i 100% will NEVER recommend GDP btw. their tunes came pre loaded and the shifting was horrendous.
