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.
