New gauges egt question?
I just installed new autometer gauges and my egt's seem low compared to other threads I have read. I'll be happy with the egt's if they are accurate. Here are some numbers I'm seeing:
EGT's 120 tune
idle: 100-200
light throttle 200-300
med throttle 3-400
wot max I saw was 700
Boost max was 20 psi in any tune but I have not tried stock yet
. So do these sound about right or could there be a problem with the guage? The only thing I found on the install was the two end connectors that attach to the gauge were to small. So I got a bigger connector and soldered those on. Maybe I got the two ends mixed up? I didn't really think about this until afterward. Hopefully that would not mess up the calibration. Thanks for any input.

That's what I was thinking comparing them to other threads. Maybe it is my programmer? I didn't really notice a difference in egt's between 50 hp and 120hp tune. The 120 tune does seem to have a little more power but still only hits 20psi. Is that just from the wastegate and programming? I don't really have a way to test the guage w/o another one installed.

My probe was hardwired, but I dont think it would make a difference if it was backwards wire is wire...

Thanks Frank. You didn't have to do that, glad you didn't get a ticket.
That will give me some good info for a comparison. Just looking at the idle warmed up, I'm off 200. If I added 200 to the other numbers that would get me in the ballpark where you are at. I guess I'll just lower my egt limit to 1000

Did you make sure the end of the probe was about dead center of the pipe before you tightend the jam nut?

. I did read on one site not to splice the wires because it could cause problems.

No, I guess I'll have to go back and read the instructions that I skimmed over. That would be nice if that was the problem.

Hey Grant, my EGT numbers are more in line with Frank's numbers, nice of you to do by the way Frank. Maybe its because the Bully Dog doesn't add a ton more fuel reletivly speaking to a custom tune. Your numbers might be right on so to speak. The only way to tell is get some custom tunes

Grant I did a little googling and found this.
I would call Auto meter and ask them if what you did would affect the readings
Bad screw up? I cut my pyrometer wire in half installing it... - Diesel Forum - TheDieselStop.com
