OBDLink MX+ and Ecodiesel

[NorthStar]

I have a few questions for you, I have been monitoring the OBD twice per day travelling 20 miles to work (one way) then back home , it’s all highway with only one stop, and drive around 60 mph, the temperature here in Northern Ontario Canada is below freezing most mornings but my truck is parked in my garage every night so I only remote start it for 1 to 3 minutes before leaving, I have been doing that since brand new.
I set up the Soot Mass Percentage gauge and it was at 47% and now it’s at 55%, it usually goes up then slowly drops when the engine temperature goes up. The other gauges that I set up shows 33 regeneration cycles and only 2 interrupted regeneration cycles in 24,000 miles so a regeneration every 700 miles, not bad at all.
My question is, do you know at what percentage does the regeneration start? and how long does a regeneration last? I have never had a warning on display to keep driving because a regeneration had started. I’m asking because I have only 27 shifts left then I am retiring after 35 years as a machinist in the deepest base metal mine in the world, I then won’t be travelling on the highway 4 days a week, I haven’t been working on Fridays for a few years.
By knowing when a regeneration is about to start I could plan a highway trip.
I plan on using my wife’s Jeep more often when doing short runs and use the truck for longer trips to visit our children or my in-laws at the cottage.
We are planning a Florida trip then a Newfoundland east coast trip next year, towing a small travel trailer with my Rebel diesel.

My regens (and I’ve heard others with the 3rd Gen Ecodiesel) have been occurring about every 700 miles as well. The soot mass will fluctuate with city versus sustained highway driving as it passively gets burned off on the highway but the active regen seems to be about 700 to 750 miles regardless of soot mass.

Ok thank you. I am in kilometres here and it is about every 1,150 km. Do you know how long it takes to do a complete regeneration?

US Daylight Savings Time or normal Canada time?

Seriously, here in our part of Texas the speed limit on the interstate highway is 75 mph. I typically do 75 MPH and I think it takes about fifteen to twenty minutes. I’ve never timed it to be honest…just keep driving until the regen gauge goes from 1 to zero.

It is nice up here in the summer, daylight past 10 pm but the winter months with the dreaded time change, it’s going to be dark at 5 tomorrow.
Thanks for the reply, I will keep a close look at the gauges.

I know the feeling…I grew up in central Alaska. Always enjoyed fishing in broad daylight at 1 am in the morning in the summer but hated walking to school and back again in the dark. It took a while getting used to “regular daylight and darkness in the lower 48!”

That is a big change, happy to hear that you actually experienced it.
My wife and I will travel with the truck and trailer to Alaska in the summer of 2023. My in-laws did and really enjoyed it.

See sequential pics below.

1. Download OBDLink App.
2. Plug MX+ into OBD outlet and sync up your iPhone Bluetooth with the MX+.
3. Click on the little car icon in bottom left corner and enter ALL data for your Ecodiesel.
4. Once done, it should ask if you want to download specific data from the OBDLink site to your iPhone so it can read Ecodiesel specific PIDs…do it.
5. After this is done, go to Displays and start choosing your displays…follow the pics provided below as a step by step guide as they are sequential. Repeat for as many different gauges as you want.

NOTE: PIDs for Ecodiesels are under the “Engine Control Module (Diesel)” as seen in pic #7

This is my first diesel engine. I just bought and received my OBD2 MX+ for diagnostic purposes. Can you shed more light on the benefits of using the gauges you added? Also, are you using other gauges besides the ones you posted? Thank you for your informative how to post with photos. Learning a lot in this forum community.

For me, each gauge serves a purpose as follows:

Top Left - Indicates if the Ecodiesel is in regen or not. If 0, not in regen. If 1, it is in regen and don't stop driving that thing at highway speeds until it completes the regen cycle.
Top Right - Inlet DPF Exhaust Gas Temp Sensor (temp in front of the DPF). I monitor this simply as another means to monitor exhaust gas temps at various sources.
Middle Left - This indicates what percentage of soot you have in the system and once it gets to a certain level then the truck will go into regen. Watch this when doing all short trips and you may need to make a highway run every now and then to get it back down otherwise regens may occur more often.
Middle Right - I monitor this simply as bit of information on how the ridiculous EPA mandated system is working.
Lower Left - Temperature of the DEF in your tank. I monitor this to keep an eye on how hot my DEF gets as heat can degrade it over time. In Texas it gets hot, very hot.
Lower Right - Exhaust gas temp post turbo...this is critical to cool down and ensuring the turbo is cool before you shut it down. Failure to cool a turbo can lead to premature failure.
(The three in bold above are the most important)

I'm no expert but have owned diesels for years and know my way fairly well around them. Other owners should chime in with their advice as I'm always learning on here too. The beauty of the MX+ is there are so many parameters one can view that each person may have a different set up depending upon where they live, how they drive, weather conditions (extremely hot versus -50 degrees), towing/unloaded, etc. And no, I don't have anything to do with MX+...just a satisfied user.

Well I have good news and I have great news. Good news is I got a full refund for the OBD Link, the great news is that I received an email from OBD support after getting the refund notification, he suggested to change the year of my truck in the vehicle editor, so 2021 instead of 2020 then rescan the PIDs and now everything works, It’s hard to believe that after almost 3 weeks of frustration, back and forth communication delays and all it took was to change the year of the truck to make the OBD link function properly.
Hopefully this will help others if they come across the same scenario.

How did you rescan the PIDS?.. I’m having the same issue as you

Thx for all your help!! Got mine set up…

One more question… on the default gauges, does your O2 Sensor 1 and/or O2 Sensor 2 show a reading while driving?? Mine does not.
Appreciate any feedback.

I don't monitor O2 sensors. I had one go bad shortly after purchase of the truck and the CEL told me it was faulty. The dealer replaced the sensor, and all was fine again.

I’m noticing that a lot of gauges aren’t working..

Keep in mind that there is typically at least two or three different PIDS listed for the same one. You may be tagging one which is simply on/off such as the dummy gauge on the cluster (warning light on/warning light off). In this case, the gauge will read zero or null until the warning light goes on and then it will give you a 1 or another value to indicate it is on. You should keep looking as there should be another way to access the PID which will give you “live readings” provided it was designed to do so by Ram.

Thank you.. I will try and choose the other ones and see if they work.
Even my boost psi isn’t working

Yes, the boost gauges I initially found were not working either and then I found these in the attached pic (see the two at the top)…still playing with it to find the correct gauges I'm seeking:

 

[NewLove]

Have anyone found the correct gauge for turbo boost pressure and Regen alerts?..

These are the twelve gauges I monitor and they show boost, when in regen, number of regens, DEF urea percent so you know if your urea is going bad, etc.

Thanks.. how much boost can this turbo produce?..and shouldn’t it be in psi?

There are a number of gauges for boost as follows (feel free to utilize whatever one works for you):

Is it normal to have a boost psi of 14 at idle?
Even when I **** the truck off the gauge reads 14 psi?
