But if you are doing long hauls an EGT gauge would be a better investment. When I am towing I keep the eye on my EGT gauge and will back it down when I am going up a hill to keep the turbo from frying. When I pull off into a Rest Area or Fuel Stop, my EGT gauge is almost always in the safe zone before I get parked, If not I unhook my seat belt and a couple other things before I shut down. Typically it only takes seconds on a Diesel to cool off the turbo, not minuets.
What do you define your temp settings as? Safe is what... too hot is what?
I have an EGT probe mounted in the entry of the turbo, probably about an inch from where you have yours indicated. At cruise (not towing) 70mph indicated, 73 GPS, I'm reading right at 1000 degrees and about 7 lbs of boost. If I STOMP on it, the highest I have seen is 1350. In normal driving, the temp drops down to 350 / 400 pretty much anytime I pull my foot off, and it drops within 10 seconds or so. This is bone-stock, without any chips or Edge modules. I'm interested to see how your numbers compare, since the EGT is a new thing for me.
The CRD has also been harder to start since the new engine, and it smokes more on initial startup than the old one did. It doesn't seem to smoke while running normally, but yesterday it felt like I didn't have much power, and it WAS smoking a lot (just before I put on the boost gauge, of course) then 'like flipping a lightswitch' it woke up and has been running fine since. I think I have a glitching sensor, but I don't know which one.
Thoughts?
Mine has spiked to 1400f for about 2 seconds when I was accelerating up a steep hill with a full load on the trailer behind me. My tach was at 3500 RPM, boost at 20 PSI and I had 5 PSI of back pressure between the turbo and the cat. I suspect my temps will drop and boost will go up when I install my Magnaflow Stainless Steel Muffler. My one observation is that high RPMs drive up the EGT more than torque. Using cruse the trans down shifts and revs the engine high, use my foot and I can climb a hill with out having the RPMs going up so high and the EGT is cooler, even going the same speed with the same load up the same hill. The bluffs I have to climb are steep, but not as long as Love-land Pass, perhaps some Love-land Pass climbers with an EGT gauge should report their observations.
Sensor problem could be a plug that is not fully seated or corroded. I have fixed many problems other shops piled on lots of parts to no avail, then all I did was clean a sensor plug. If you can get Wurth Contact-oel (sorry omlots aren't on my keyboard) un plug the sensor plugs, spray, and replug. Other stuff like CRC works but not as fast or as well.
Good luck
