Not doubting this is in fact true but, how do you know which one is reading true? I have a bluedriver, I'll compare when I go home tomorrow what it reads versus the "analog" gauge.

 

Maybe someone with more electrical/instrument knowledge can help clarify what happens from the sensor output to display vs output to a tuner?

The Dash-Hawk engine monitor displays what the OEM sensors are telling it - but your Blue-Driver will read accurately too - as compared to the glorified "idiot light" the factory H2-0 gage is...........

Surely the dash is displaying what the sensors are outputting as well. Why is there discrepancy?

Displaying it yes - accurately no..................  GM feel good factor - good enough info for the average driver - Why don't they give the Duramax some kind of display when the diesel particulate filter cleaning is active - the whole reason I got the engine monitor.................

I feel cheated lol. Those tuners and plugin analyst devices are pretty amazing for what they can display. Thanks for the info

I just can't understand why with just the slightest engine load or downshift with increased rpms the water temp would rise that quickly, reguardless  if the guage is accurate or not. Wonder if it's something to do with the sending unit or perhaps it something mechanical like impeller speed or something. I haven't looked at the dynamics of the cooling system.

got ahold of a scanner, and fro. What I see the temp gauge is reading low actually. And the temp rise is rpm based, and with engine load it rise more . Normal cruse speed of 60mph and rpm of 1500 it's running 214 and showing 210 put it in manual mode same speed and rpm of 2200 temp goes to 220 on scanner and gauge show about 215, punch it or go up a long incline and temp goes to 228 gauge shows slightly over 215 closer to 220. I don't even have a load on the motor such a trailer or anything just increasing rpm makes the temp rise.got ahold of a scanner, and fro. What I see the temp gauge is reading low actually.

was hoping someone else with the same truckwould chime in if they are experiencing the same thing. I just watched a video of the gauntlet test with a 17 6.2 he is pulling a 10,000 trailer, I screen shot the temp it's really high. Now granted the shot is from the left side so it's not quite as high as it looks, but still pretty high

First off, please change your font. Why choose anything other than the normal font, just annoying to read.

 

also tfl truck is towing 10k pounds, up a hill, at wot, for like 10 minutes straight.

 

I’ve owned cars that would blow up if you went WOT for 30 seconds straight, let alone 10 freaking minutes.

 

This isn’t a tractor trailer, or a diesel.

 

10 minutes straight at WOT for a 420hp sports car engine is absolutely nuts

Sorry about the font, I didn't change anything, I think it's because I copy and pasted. The dealer is just going to say it normal, it hasn't set a mil, and not saying over temp. I'm sure they will say it's with in normal operating temp.

I’m sure it’s normal

 

what is the only thing that could cause extremely fast rise in water temps under low load conditions

 

extremely efficient transfer of heat

 

its the only thing that makes sense

 

The water is heated by transfering heat from the coolant passages. A lot of temp fluctuation is great if you ask me.

I see this engine uses piston cooling jets , I wonder if there is a malfunction in this system that could be causing the temp to rise. And is there a way the tech can check operation of the system without tearing into motor

You do know GM tests these engines the ones your talking about at WOT for 1000's+ hours straight at even higher RPM's before it's validated?  SO 10 minutes @WOT is absolutely nothing to these engines...NOTHING!

 

Also GM's validation and powertrain testing is NIGHT and DAY over FERD not even close....GM does not play when it comes to V8's

Calling bullshit on that, 1000's of hours straight with no stopping....lets see the evidence

You made the claim, I called BS, it's your turn to prove it. Got any evidence of this?

 

I'll eat my words if it's true, but come on, 1000's of hours at WOT?..... yeah f-ing right

      Missing thrust bearing? And oil selection

      By Chuck FB · Posted

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.
