EGT Temps Towing

[Cajun Po-Boy]

I'm interested in any diesel owner who has an EGT gauge installed to let me know what your temps read under various towing conditions ( flats, hills, mts)?
Also, let me know if these numbers are with a stock truck or tuned engine.
Thanks!

Stock tuning
Flats, 65mph,1000
Hills,65,11 to 1200

Down pipe with 4inch back and flow thru muffler
Flats 65, 800
Hills 65 1000

EFI heavy tow tune
Flats 65, 900
Hills 65 1000

Wide open 1200 max all the way to 75 mph and 12.5mpg

Empty 65 650, 75mph 750 degrees
You will be ok in stock form towing anytime but add power and things change

03 6.oh no, 4 inch turbo back:
flat land - 600-850
2-3* grade - 800-1100
4-6* grade - 1250

I can get it higher if I pull harder, but it will hold 70 on an 8* grade.

Truck in sig. 850-1100 depending on how hard I'm pushing it. In the N Ga mountains, I've hit 1250 but haven't had it de-fuel yet. Most around 1325 in the 6.4s that will happen.

Thanks guys for the numbers!

I've been putting off way too long not installing an EGT gauge, getting done before spring...wanted y'all's numbers to compare with mine when I run stock before getting back on "tune" ,)

As important as it is to control EGT temps in these diesel's, you'd think the Big 3 would offer them as factory package in these trucks!? Especially when most of them are only recommended to fun a few seconds in the 1350 degree range which most of us can do when climbing grades...sorry, didn't mean to get off OP's topic...wait, that's me! LOL

[jeeplj8]

My personal opinion, no one should tow with a turbo diesel without knowing both their EGT's and boost pressure. For less than 15 bucks you can get a bluetooth OBD dongle that will broadcast that info to your smart phone.

I use the Edge Insight 83830 on my truck. It is just a monitor, no tuner. I love the parameters you are able to watch with this device. Takes approximately 30 minutes to set up and 10 to install(not counting painting the pod). Take a look.

With a factory truck their is no worry up to GCWR. So no need for a pyro, but it is scary what they sit at on a long pull. The engineers did their home work and they know, that is why their is a limit on the truck weights.

Another note/example of this...Ford's come with boost gauge from factory...why not GM's trucks? I've read that boost is also an important parameter to watch, so one manufacturer things the driver needs the info and others don't...confusing!

I am sorry, but I have to vehemently disagree with this statement. It is clearly not accurate if you pull with a Ford 6.0. I would say it not accurate if you pull with a Dodge with the 555 or 610 motor as well, plus probably many others.

There are literally thousands of owners who have blown up their diesel towing well within GCVWR.

The trucks as sold do not offer any actual indication of engine parameters. The gauges on the dash are designed to indicate a "range" not any actual data point. For example, the Ford engine temp gauge will not indicate the engine temp is high until it has reached 220 degrees. That means at 219 degrees it will indicate NORMAL engine temp. Most 6.0 head gasket failures occur at engine temps below that. My transmission temp gauge is even more of a joke. The volt gauge registered normal at 11.9 volts charging, see a theme here?

On the Cummins 610 I had, the temp gauge would not register anything but normal until the engine hit 220 as well.

Again, if you own one of these trucks and are not monitoring these temps, you are WILL be one of the people on these forums talking about what trash XXXX builder sold you because your truck blew up.

here is a short article about the bluetooth option and android phones (you can also use with a laptop and free softeware:
ELM 327 OBD-II Bluetooth Scanner/Transmitter Review

here is a link to one such bluetooth scanner, there are tons:
Yongtek ELM 327 Bluetooth Obdii Obd2 Diagnostic Scanner, Elm327 Wireless OBD 2 Scan Tool Check Engine Light CAR Code Reader : Amazon.com : Automotive

and an android app, again there are many:
https://play.google.com/store/apps/d...cnF1ZWZyZWUiXQ..

So - for less than 20 bucks you can see what your real engine temp, egt, boost numbers are, and read any codes.

BTW - one interesting thing I have found with my code reader (I use an Edge Insight) is how many codes I get that do not light the CEL. Most are not significant, but my FICM started throwing codes and my Insight caught it. Saved me a roadside emergency.

Typically between 650°-750°. It's pretty rare I hit and stay on the 800s.

I use a SCT Xtreme to monitor 6 parameters and have fuel pressure gauge on the window post.

In stock form, I believe most trucks will start cutting fuel to engine when temps approach a critical point. While I'm well aware of what exhaust temps will do, most owners (we here on the forum are NOT most), probably couldn't tell you what an acceptable temp is without a dummy guage. Start adding tuners, and taking away the safety margins built into a stock truck, then you need to know what is going on. I pulled an intake valve up through the head on a supercharged 454 boat motor while tuning the fuel curve. It took about 5 secs and the valve looked like champaign flute.

Jeep. you are right about the temp monitoring. That being said I've never used a pyro on my 05 d-max ,shame on me. To top it all off the 04.5 and 05 d-Max are
notorious for running high temps, some have the problem some don't. GM never got it figured out even with their service bulletin on the problem. So far so good for me and the 05 D-Max.

I always run at 210 not pulling on the flat and mtns. Towing about 12,500 lbs on the flat, still 210 and mtn. pulling I've seen as high as 235 on the steepest grades. just thought I would offer this extra bit of info.

This should be in towing forum. ......

Jeepj, the OBDII doesn't work in all applications and where it may work, it may give incomplete data. It is a nice tool, but not something that I would depend my engine's life on.

Would the scanner or monitors void any warranties if dealer finds codes saying it was on there?

NO. There is a huge difference between a monitor or a code scanner and a tuner. Scanners and monitors are one way, they can only read data. they cannot write data to the truck. A tuner writes data to the truck.

Yes, I've been looking at the EDGT CTS...very nice unit & expensive BUT let's you see so many parameters, as you commented.
Additionally, the CTS let's you control your tuner power levels on the fly and you can add the backup camera option pretty easily...unit does a lot for the price IMO

this question is about what we pull with 3/4 to 1ton diesels and yes their is no need of a pyro, is that 555 or 610 installed in a 3/4 ton??. and the 6.o problem is the egr cooler after that fails a lot of parts fail and nothing to do with egt and I also have friends that have them and 1 with 300k and not 1 single problem and he tows for a living, have you towed at max GCWR with a pyro and seen the temps? I have and they do not get close to going over 1375 which is the max continuous for a GM unit. if the engineers think we needed to monitor the temps it would be standard, yes it is nice to know but not required in a factory tuned 3/4 to 1 ton diesel (current years)
