2013 3500 EGT Gauge.

[Beav76]

This is my first post. I have lurked for a few years and been quite impressed with the expertise at TDR.



I have three questions:



1. Will an Edge CTS or CS monitor EGT through the OBD-II port on a 2013 3500? I understand that in general the Edge products can monitor EGT through the OBD-II port. I am just not sure they will successfully monitor EGT on the new 2013 3500's. When I contacted Edge they were completly unhelpful and were unsure if the CTS/CS would monitor EGT on a 2013. Does anyone have specific experience with the edge products on a 2013 3500?



2. Assuming I can monitor EGT with Edge products, where is EGT monitored using OEM data (I am trying to avoid installing an EGT probe)? Is this an ideal location to monitor EGT?



3. Are there other options for monitoring EGT through the OBD-II port?



Thanks.



Dave

Based on some 2nd hand information about the new trucks, they do monitor EGT's but are not exposing that for consumption by other devices. Yet. When and ever is open ended.

You would need to install a probe to monitor pre-turbo temps. I suspect, but have not confirmed, the new trucks are monitoring EGT's post turbo for regen pueposes.

Are you planning on modifying your power or leaving stock. If stock there is no real need to monitor it. It will never get too hot to damage anything.

Thanks for the info to date. Just to clarify - I primarily use this to determine when it is safe to shut the engine down. I find the subjective recommendations, in the owners manual, on so much time given widely defined operating conditions to be inadequate. I am particularily concerned after a tough pull towing a 32' HitchHiker 5th wheel.

Cerberusiam: I am hoping someone can confirm where Ram is monitoring EGT. If it is post Turbo, I am hoping that is adequate (I know it is not ideal). Any comments would be appreciated.

Sag2: I am planning on leaving it stock. On my prior 2004. 5 I used 350 degrees (pre-turbo) to determine when to shut down my engine. That could take a long time given an uphill route or a long uphill pull with the 5th wheel. I think I still need to be concerned on shutdown temp for the 2013.

You need to be aware that the turbo on your 13 has a water cooled center section. This makes a huge difference on cool down times. I know that this is not really the answer to your request, I too went from a 04. 5 to the 2013, I miss my pyrometer.

I towed by the Pyrometer on my 98 12V, it was a needed item. With the new trucks they are a waste of money unless you have modified the truck. The new trucks are not going to hurt it's self if left stock.

Use common sense when shutting truck off. Normal driving I never wait. After towing our 28K combined load I would wait about 5 minutes.

The pyro probe on the 2013 is in the exhasust manifold near #4 port. I too like to monitor egt, but as noted above, the turbo center housing is now water cooled, and as sag2 posted, the engine should not get too hot if left stock.

A little OT, but what turbo is the 2013 running now? The HE351VE used from 07. 5-12 only has water cooled electronics, and not the bearing, so it's nice to see a turbo change to a fully water-cooled setup.

The edge cts will not monitor egt temps. I spend a some time in dry pastures and thought it would be nice mainly to monitor regens but unfortunately it does not seem to do that either but haven't had it on for very long. Glad I didn't buy a cts specifically for my 2013. The gauge selection, I think, is rather unhelpful, it is nice having a code reader, just my 2 cents. Don't get me wrong I loved it on my 2011 duramax. I also thought edge was not that helpful with this application.

Long time trucker here. If you are pulling normally on a some what flat road, taking an off ramp and pulling into a fuel stop or some such, you have cooled your engine enough. Shut off right away is ok.

If you are pulling a big hill, and pull off right into a rest area, I would let it run. A few minutes would be enough of idling to cool it down.

Beav76,
Is this your first 6. 7L engine from Cummins? The reason I ask is that the stock 6. 7L engine in my opinion will never get below 350F when idling. My 08 when stock would stay around 400 to 450F after 5 to 6 min's of idling time. So I gave up on letting the engine idle to 350F, I would shut it down at 450F. I also notice that I would tend to be at 450F EGT's when I stop the truck as I pulled into any rest area regardless of pulling conditions.

Watching EGT's at idle has never been a good way to measure cooling off the turbo anyway. The only thing that made a difference was the time invloved in getting the manifold temps to cool down to a certain point. It was and is all about time and temp in the turbo not the manifold. Even if the turbo is water cooled once the engine is hutdown heat transference essentially stops as does oil flow. The water and oil flow are what cools the turbo down so it doesn't cook the oil in the bushings\bearings. Only way to insure that is run it as low boost for a period of time regardless of EGT's.

The only time cooling down is an issue is pulling directly off the road on an exit or rest area after a long hard pull. If the truck isn't workig hard it won't be an issue. If one pulls off and wends his way into a fuel stop or some other area that is not directly on the road a lot of heta ahas already disipated and idle time should be able to done at a minimum. Get a Buzz Lightyear ray gun and track the temps on the turbo in different situations. That will tell how long a cool down is needed in different situations. No guessing there.
