Questions regarding the OBDLink MX+

I hope that I am putting this in the correct forum. 

 

I have a 2021 GMC Sierra Elevation 4X4 with the 3.0L Duramax. I bought the OBDLink MX+ so that I could pair it with my phone and be able to use the app to monitor certain things as I drive. Either I don't know what I'm doing (most likely) or the OBDLink isn't reading certain things correctly. 

 

I would like to be able to see how long it will be until my truck goes into a regen cycle. I'm not really sure if the OBDLink can tell me this. If it can, I don't know what the exact setting (I think they are called PIDs) is called. 

 

The temp gauge reads about 25° hotter than the truck's gauge does.

 

The torque gauge usually reads at <100 ft. lbs. This obviously doesn't seem correct. 

 

The horsepower gauge reads at <50 horsepower at all times. Again, doesn't seem to be correct. 


Obviously, I'm doing something wrong. I don't know if I have chosen the wrong setting, or what. I didn't have any issues at all with setting up the device or pairing it with my phone. Any help would be greatly appreciated!!

I have a 2021 Silverado with 3.0L and purchased a obdlink mx+ using bluetooth. OBDLINK recognized my 2021, under settings updated firmware, get enhanced OEM add ons - 2021 not available I selected 2019.

Dashboard has two screens one with radial gauges and the second with square gauges. set up radial gauges to have mph, eng temp, rpm, maf, fuel rate, battery

Second dashboard is square gauges (swipe screen) I set up eng pwr, eng torque, def tank level, eng temp, normalized trigger for def regen, dpf regen status. second dash board set up using add display select digital gauge next select dark next select pid next select SAE PIDs a very long list comes up i swipped to the bottom then started scrolling towards the top you will find the dep regen items select one to create a garage repeat process for other items to add

 

I just set up and will monitor the normalized trigger for DFP regen, currently reading 50% I believe when it approached 100% regen will start. DPF is at 0.0 do not know what it will read when regen happens

 

I will report back after I see a regen status. Some screen shots attached

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Actual Full Screen CarPlay on Refreshed Silverado/Sierras.

      By Greg3160 · Posted

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
