A little update. You guys may call me fucking crazy for my obsession with gauges but it really isn't an obsession with gauges, it is an obsession with data. This isn't because it is some old shitty truck. I am the same way with my H3 and if I had a 2024 diesel I'd probably have 3 banks i-dash's monitoring everything. The difference is the new trucks can be monitored off of 1000 OEM PCM PIDs where I have to manually add most of it but it doesnt matter, new or old, I want it monitored. So I added 3 new guages.
A backstory to me being neurotic, when I would do 1200 mile road trips in my H3 every gas stop I would be touching the hubs, the rear diff cover, the t case, checking oil even though I checked it 200 miles ago at the last gas station and that is over and above all the PIDs I monitor while driving. I have a temp sensor in my doubler box because some have had overheating issues with another brand doubler box so I am neurotic. I also have an infrared temp gun with me to temp gun stuff all the time. With that said, it has saved my bacon in the past, on UA 2018, we stopped at a gas stop and I touch my hubs for the 1000th time and finally one wasn't the same as the others. It was PIPING hot. I pull it apart and I had twisted an axle shaft that cracked and bent and was causing a ton of drag on the hub. It was a wild break. It was so hot I burnt my hand immediately. If I didn't do that I would have 100% destroyed the wheel bearings and in UA fashion, they keep going, you have to fix it and catch up. Instead of an on the roadside fix with a potential for self-welded races to hubs or other drama, I unbolted the full float shafts at the gas stop, slapped in some spare shafts and carried on.
So, the 7.3 doesn't have shit for info. Water temp is only a PID if you have a manual trans. Oil pressure is a stupid switch on the dashboard. Over or under 5psi and it goes to the same spot on the dash. It is an idiot gauge.
I added backpressure, coolant temp and low pressure oil pressure. I moved High pressure oil down to the low pressure oil spot and exhaust backpressure by the boost guage. I wanted exh. backpressure since I will be adding an exhaust brake.
So the A pillar top to bottom I run exh. backpressure (just added,) boost, fuel pressure, EGT.
Then on the dash I have all 6 tires on TPMS. I just saw an F550 this week driving with a completely flat rear tire doing 70 mph and they had no clue.
I'm sure it wouldn't be long before the carcass gives out and destroys a brake line.
Then the new pod at your knees is low oil pressure, high oil pressure, and coolant temp.
Then on my radio I look at trans temp, oil temp, IPR readings, tq converter slip, injection pulse width and voltage.
Id still like to add a diff temp sensor and t case temp sensor as I know people who have overheated both of those before. It's rare but if a problem can be caught early, it can usually be solved before it's too late and you're up shits creek.
So, there's a peak into my life where I just worry constantly about anything that is powered by an engine.
