Need Help Identifying Controller

The 1999 F350 7.3 I purchased last week has a controller in the engine bay. Previous owner did not know anything about it. I looked at the Performance Diesel Parts website but did not see anything to go off of and an internet search did not bring up anything I could see that would help. Short of sending them an email with the part can someone here maybe identify what controller this may be? I have never programmed a diesel or really looked at programmers in the past so its new territory for me. I have to diagnose a miss from the injectors and don't want any surprises from an outside failure...

Thanks in advance

Where does the wiring lead and connect to? I've got no idea on that thing either but knowing where it's tentacles go may help work out what it's doing.

call them on the phone first and describe what you have,
that tuner is no longer being sold, makes it hard to find.

I found an old link on this forum talking about something like that
https://www.ford-trucks.com/forums/2...tml#post174584


and this thread talks about a company of the same name
https://www.dieseltruckresource.com/...hey-go-216799/
having gone extinct.

use this page to contact Diesel Dynamics and send them a picture of what you have,
it is an Extinct tuner, but surely they would have info on it.

A topside creeper!? Those things will make you soft. Next you'll want wrenches that don't slip and bash your knuckles, and before you know it you'll be drinking beer from a glass. They are freakin sweet though, enjoy that one.

I was going to say the same thing, only to scroll down and see that Cody clocked in.

Follow the wire harness that trails off to the left of the photo, and take another photo of where that harness terminates.

We suspect that the "controller" wires will lead to the wire harness that serves the ICP (injector control pressure) sensor.

I did get an email back from Diesel Dynamics. Different company, they were nice and wrote back that they forwarded my email to the owner of the company that closed shop to see if I get a response.

Here is a pic where the ECU termination happens, it is taped up in this harness. I will pull it apart and ensure a good connection this weekend when I am under the hood...

Bada bing Bada boom

Bury your question in a tomb
As you can safely assume
His answer was right.

It is a glorified 10K mod (or 5.6K, depending on if the resistor is inline or straddled with ground)... hidden in a "black box" to make it look like more wizardry than it really is, in order to charge more money that it was really worth.

OK,

So safe to remove it and repair the harness? Maybe figure out the resistance and add it back later if I want...

I have the Forscan cable on the way and the software on my laptop. Just dont want bad readings while I figure out the miss in the engine.

I just needed to get up on the engine and see what's going on. The unit looks to be an edge EZF1000, I just need to open and see what power level it is set at. The topside creeper takes a bit to get used to but it will save my back!!! Started the truck this weekend and there was no miss.
