Deleted 2012 ,was wondering if the ecm uses the probe in the block off plate or can i use it for gauge?

I used an aftermarket CTS2 and EGT probe in the plate. I think it has been done using the OEM sensor but the problem is your tuning files may turn off that sensor or you need to reroute the OEM harness to fit correctly.

Only the mini max is programmed to use a DPF temp sensor to read properly. Any other tuning it’ll read accurately with a dpf sensor in it to 415* and max out. You really don’t need to worry about egts with these 6.7s. The intercooler efficiency keeps egts down very low.

When I’m towing in 90* temps the CAC temps are about 115 goin down the highway. That’s on the h&s performance tune. If it falls down to 80* or so then temps will sit at 86/87 because that’s where the thermostat is. So it’s efficiency is nearly 100%... on the performance tune, even while towing uphill, the egts stay around 1100 maybe peak 1200 if I’m being hard on it. That’s read with a cts and edge probe. On a tow tune I’d doubt you could even get it high enough to hurt anything. This is 11-14 trucks. I have a 15 pump and 17 turbo I haven’t had time to install yet. I can report what difference it makes when I do.

The low temp tstat on the secondary cooling system for the CAC. It’s fully open at 86*

There are two thermostats in the secondary radiator.. my mistake, the low temp starts to open at 86 and is fully open at 113*. The high temp thermostat is fully open at 140*. I don’t remember where it starts to open at. The coolant flows through half of the radiator first, cooling the trans and egr cooler, the CAC and fuel cooler is cooled after coolant travels through both halves of the radiator.

Right....113*.....Okay...I see what you are referencing now and when. I see roughly a 25* delta (Intake temps to post-CAC temps) during all modes of operation regardless of outside air temps.

Go over mountain passes quite a bit,I feel a bit uneasy not knowing. I'd like to see oil pressure too. Can ya run just a monitor like say the edge display with some kind of aftermarket sensors? I have a sct x4 but I don't much about it. Can't find egt's on it and it bulky to use a monitor.

I run the Insight CTS2 which has plenty of PIDs to view. Get little unit with expandable sensors that you can buy. Since OEM oil pressure is a switch you will need to run your own pressure sensor. To be honest oil pressure isn't as much a concern as are the temps. The PCM will shut down the motor on high oil temps long before oil pressure causes damage.

the egr egt probe can be used with the block plates to give you pre turbo egts. doesnt read under 392, not sure what the max is as i havent seen over 1000 egts since deleting.

thats using an edge insight cts 2. the minimax comment is wrong.

I also use the cts with the expandable egr probe kit. Probe in the block off plate wired directly to the cts head unit an a suction cup stuck to the windshield. No troubles with this setup. Im tuned with the x4, to small of a screen and too clunky to monitor with for my taste.

I tried using the original egrt probe and the dpf egt probe in the block off plate and monitoring the egrt PID, did not work.

I have seen more oftentimes the trans fluid temp creep uncomfortably high than the egts when towing heavy.

What's uncomfortably high if you don't mind me asking? I often tow a 32' horse trailer that can get into the 17-18k lb range and my temps are generally in the 21x at 80-90 ambient and then it's only for short periods of time.

Iirc 225+ pulling long grade trying to make miles so I don't have to park in the dark, so driving too fast for sure.
