Wives 2018 honda... I want a egt gauge.

Dealer says installing gauge will void warranty.  

 

Question... modern turbos.

No big deal on idling down temp before shutting off?

Cooldown still applies to any turbo including smaller turbos on a gasoline engine. The turbo bearings can coke up from the excessive temperatures at shut down. The only reason a deal would void the warranty is that racers tend to use the pyrometers to watch for excessive cylinder temperatures and meltdown.

Thanks...I'm not going to race wifes CRV. ??   

 

And not sure if turbo is water cooled or not, which might a difference?  

 

Honda forums,  mostly kids messing around.  Little practical info that would benefit everyday common sence driver.

 

Thanks

meh drive it hard put it away wet, it has a warranty.  

 

 

really though I wouldn't worry about it.    Just like I dont worry about egt's on my 2018 3500.

I was thinking the same thing when I read your first post. I being water cooled would make a huge difference.

 

I would not worry about EGT's much. It's important in diesels because the amount of fuel demanded when the vehicle is modified to flow more fuel, start to out match the amount of air available for combustion. With a gas engine, you are are running a pre-tuned Air/Fuel ratio, and I assume a factory tune, that will not allow you to get take the turbo outside of it's efficient range of operation.

Out of couriuosly.  How much better comfortable ride and braking on 2018

Ok, let us get science into the answer then. Grab an IR temp gun and measure turbine housing after a good run and report the temperature.

so much better than a 2nd gen.  

 

 

 

SOOOOOO much better

I've seen a water cooled Mitsubishi turbo glowing red on a Volvo after a hard pull up a long grade.  That turbo had over 400K miles on it with no cool downs before I changed it out with a used cartridge.

Good idea.  Probably measure next week after going on longer drive.

 

If I remember right...Oil starts to coke up around 500?

I wouldn't worry about a car. They are engineered for being shut down like a non-turbo. 

 

Besides, the loads are so light and you can only make full power for so long that there just wont be too much heat in there. 

 

But, if there is a factory pyro you might be able to read it with an OBDII gauge. If there isn't a factory pyro then all the more reason to just drive it.

I don't worry about EGT's on my '18, but I still do cooldowns. Usually only a few seconds in P, but when I've been towing I give it longer.

.....and a 3rd gen.... and a 10-12 4th gen. 

 

The longer control arms do wonders for the front ride, and so does the auto-level with softer springs.

If you can find it  buy the time you open the hood and get in the uncomfortable position to read the temp, it will be cold off anyway. 

Oil used in cars today probably has something to do with it also.

On the other note, I beat the crap out my wife's x3 every time I drive it, quick little 4banger, tires are expensive though. 

Well... I guess that is a dud... I'm still playing with old 90's V8 engines. 

My next ride is going to be either a Edge or an Explorer with Ecoboost and I doubt I'll be concerned with exhaust temperatures. The electronic side of today's vehicles have incredible control over the mechanical. Over temperature will cause electronic induced loss of power and will protect the mechanical of the vehicle. 

 

That's what's bankrupting the owner operator truckers now days is say a NOx sensor goes bad for the SCR system. The programming gives little opportunity to to make it to a shop for repair before a severe derate occurs known as the "5 MPH drive of shame". EGR faults cause the same type of derate. Makes it hard when the tow company charges you $400 just to answer the phone.

 

Bad part is for GHG14 and GHG17 diesel engine owners is it's not if but when you will have an incredibly expensive sensor failure that 9 times out of 10 is not covered under warranty because it's a "maintenance item".

 

I can't vouch for the gasoline counterparts on how sensor failures and such are handled.

Unless you think you can beat the system like this greedy knuckle head tried to do and end up with federal charges.

Yep. Pretty much in the CARB and EPA's eyes all tuning is illegal especially when it involves removing emissions equipment like EGR, DPF, and SCR. I can't think of a legal tuner on the market right now. Probably even most gasoline engine tuning is illegal, the Diablo Sport I have for my 04 Mach 1 allows me to turn the downstream o2 sensors off which allows for catalyst removal without the check engine light. I think as long as there is the internal combustion engine there will always be someone trying to defeat emissions and make more power, CARB and EPA will always be there to issue and collect the fines whenever the emissions defeating tuning is found.

 

I bet even the highly sought after Adrenaline that everyone wants for their 2nd gen Cummins is illegal because it will increase particulate matter output and NOx output. Diesel emissions started in 1994 which why you see Diesel Oxidation Catalyst on P-pumped 6bt engines such as my 97. My 97 is probably illegal now by 1997 standards just because the P-pump has been tweaked.

 

• 1994 PM emission standard of 0.10 g/bhp·hr
• 1998 Gradual tightening of the NOx limit to 4 g/bhp·hr

Shouldn't this be something changed at certain intervals to prevent from expensive bills. Or simply no one knows about it till it's too late ?

Are you still keeping the truck, I thought about getting a Highlander for the wife, expensive though.

The only ATS component I've seen with a maintenance interval is a DPF. I've heard horror stories of dealers and manufacturers always blaming something up stream or duty cycle for the cause of an ATS failure. The number  one cause of ATS failure is high duty cycle. High duty cycle would be extended idle, short trip city driving. Believe it or not but heavy haul on the highway is considered light duty cycle. Most OTR truck owners refuse to understand they can not idle their engine all night. For what most spend in ATS repair to idle they could have brought an APU that provides heat and a/c and the APU is designed to run all night. Most light duty ATS fail due to high fuel usage city short tripping.

Tried to get turbo temp today with ir gun.  Hard to do as it has a heat shield around it.  Had to find a YouTube you to figure out where turbo was.  Going to give up worrying about it for now. As this same turbo Honda been using for awhile now.  

  

I would be more concerned about thinning of the oil by fuel, if it's the newer or earth-friendly direct-injected engine. They inject fuel directly into cylinder at high pressure and can overcome compression, if not all of it gets burnt it goes down pass the rings into the oil. I would recommend changing oil every 5000 with full synthetic.

Yes... actually did quite a bit of reading about this. But it's the wife's car she absolutely wanted it and had to be a Honda and all that stuff.  This is her fourth CRV,  supposedly if you drive around in second you don't have that problem supposedly and on long long trips wide open road 65 or more I  put it in Drive. I don't live in a very cold climate my put on very few miles,  but yeah I'm concerned about it I check the oil probably more than I should.
