I have an old, old legacy Edge Evolution programmer/gauge set that uses a specialty EGT probe. The probe wire goes into a little black box that that a wire that connects into the side of the OBDII connector that goes into the Evolution. I've had these go bad before and replaced them, and mine went bad some time ago and I'm finally trying to replace it. But I can't seem to find it for sale anywhere. It exists on Edge's website and doesn't say it's not available but when I click on the Buy Now button nothing happens. I'm wondering if they stopped making the thing.

If anyone knows what's up with this part or knows where I can get one would you let me know?

Thanks,

 

Whats the part # or upload a link and I will try it at my end and see if anything happens

 

I would suspect it would be a K type thermocouple. What’s in the box is another story. But K thermocouples are common.

 

This is the link with the Edge part number.

I am sure it probably is a standard thermocouple, but it's hard wired into the electronics. I tore it apart to see if it would be possible to replace it with a standard thermocouple, but it was literally molded into the plastic. See the link I posted above to see what it looks like.

 

if
did the same to me. quick ddg search no avail. may need to call em, they may have discontinued it??? Bummer if they did.

 

Is this what you're looking for:


If so, PM me an offer for it.

 

Do you have pictures of when you opened the box up?

In my jobs, I worked with thermocouples for 35 years and still do. Within the braided area, if typical K will have yellow and red insulation, Chromel+ / Alumel – alloys. You can have a cold junction, splicing of the wire, which we did all the time. What they are doing in the box, again, can vary. Repair will depend on what failed.

Nevermind - I see there is an offer.

 

Googling edge 98600 comes up with a few places that show in stock, may have been sitting on their shelf for 10 years but hey.

 

The box at least on the SCT is taking the Type K thermocouple output (Millivolts) and converting/scaling it to an analog 0-5V signal. There’s a little chip in there and basic electronic circuits.
