ISSPRO EGT Gauge

[kevhype0825]

After installing my ISSPRO EV EGT gauge this weekend I noticed it does not drop below 300 even after the truck has been sitting overnight. Once I start the truck it moves as expected but for some reason the gauge does not return to 0 when the truck cools completely. I also noticed that the very first time I started the truck after installing the gauge it sprung up to 300 and remained there until drove off. Has anyone else experienced that?

Double check the ground and make sure it is a clean, solid ground.

Just installed mine a few weeks ago and it always goes to zero (like it should) when the power is off. Maybe a bad ground, gauge or amplifier box? TDR member Pliska is listed as a supporting vendor, Isspro Engineering Manager. If the shop you bought it from can't help then maybe a PM to him may help. I'd check the ground first... it's "low hanging fruit. "

I think the above link will connect you with his profile. Good luck, I love looking at my gauges and watching my boost climb when I fly up the hills here in WA.

The issue I am having does not appear to be caused by improper grounding. The gauge works great above 300 but it just does not go back to 0 or read anything below 300.



Here is the grounding location I used.

I am also wondering if it is possible to overtighten the two mounting screws so much that they distort shape of the gauge and prevent the gauge indicator from moving smoothly? I know it sounds far fetched and I only hand tightened them but maybe I went a little too far?

Did you check the tiny screws on the AMP box?

 

[kevhype0825]

I am now convinced this is something caused by the mounting method I am using; gaugeworks triple overhead pod. I just performed a test with the gauge pod detached from the windshield / headliner and the EGT gauge worked without issue. Once I repositioned the pod, same issue returned. As far as I can see it appears that the rearview mirror wire harness is pressing against one of the terminals. I was not able to work at it for long as it got dark. I'll get back at it tomorrow.

my egt gauge stays where it last registered until I re-start the truck. Thats just they way they work.

DGlidewell, from your signature I noticed that you have Dipricol gauges. Coincidentally what you described it what I am experiencing but others who have ISSPRO gauges similar to mine have said it should return to 0. I will call ISSPRO to confirm if this behavior is what I should expect.

 

[scootergmc]

Isspro returns to zero. At least mine do, every time.

I was able to work at this issue last night and I discovered I have a faulty gauge. The gauge indicator is touching the gauge's glass face when it is at 400 and below. Which prevents it from making a full sweep back to 0.



Just my luck I guess.



Thanks for all the input on this one.

Talk to Curt at Isspro. . They will take care of you. .

I spoke to an ISSPRO tech today and he said this particular gauge should return to 0 once the ignition is switched off. This proved my observation that something is obstructing the gauge indicator.



I called the company I purchased it from and they are going to send me a warranty replacement.

glad your situation is being addressed. I prefer the way my gauge works. :-laf

It tattles on me if it did not cool-down below 400.

Yes my issue is sorted. Thanks to the good people at Geno's! Great vendor! I received my new gauge yesterday and installed it. It now returns to 0 when the key is switched off and does not jump around at lower temperatures.
