Sending my old one to him tomorrow, and sending him an IDM to upgrade to a high voltage/high frequency version. I'm stoked as well after finding him!

 

Some info from his website...

Diesel Technology of Chattanooga is owned and operated by Jonathan Ryan aka Swamp or Swamp Donkey, co-founder and head of R&D at Swamp's Diesel Performance from 2003 to 2018.

Among other projects there, he completely reverse engineered the circuit boards for the 7.3 IDM, 7.3 PCM, and the 6.0 FICM, invented the Swamp's HVHF IDM (Hi-Voltage Hi-Frequency) and the Heavy Duty 58 Volt FICM, also called a Cold Weather FICM or Winter FICM or whatever other names other companies have come up with to try and distinguish their products He also laid the foundation for all of Swamp's custom tuning on 7.3 Powerstrokes and tuning the 1999 and newer trucks to run single-shot injectors, designed the dyno test cell, ran the engine dyno and did all the dyno tuning and testing.

He now concentrates electronic module repair, working from his home shop near Chattanooga, Tennessee, goes whitewater kayaking on the Ocoee river after work, and teaches Swift Water Rescue classes to firefighters, police and rescue squads from all over Tennessee on the weekends.

There are several ways to identify the various models of Powertrain Control Modules used in the 7.3 Ford Power Stroke diesels: The DPC number, Tear Tag aka PCM Code, and the Ford part number.

The DPC (Diesel Powertrain Controller) number is found on the upper left corner of the label on the PCM connector. The numbers run from 202 to 492, and identify the hardware version (the circuit board components & layout) of a given PCM, and can be used to identify whether it is from an automatic trans, manual trans, van, etc.

The Tear Tag (PCM Code) is the three letters and one numeral printed in the largest font in the center of the label, and also on the tag on the black cover where you put a chip, which is a 2-piece label with a perforation so you can tear off half of the tag. This is the software family and version programmed into the EEPROM at manufacture. The letters themselves are random/gibberish; I've never been able to find any rhyme or reason to how these letters are derived, but the numeral designates the version number of the software. i.e. NVK0 was used on DPC-422 PCM's in 1999.5-2000 model year automatic transmission trucks. It was superseded by NVK1, which in turn was replaced by NVK2, and so on up to NVK5.

The Ford part number for a DPC-422 with NVK0 software is XC3F-12A650-BB. For NVK1, the BB changes to BC. NVK2 is BD, and so on.

Why all this detail? Simple. If your truck was built with a DPC-422 PCM, absolutely ANY DPC-422 will work in your truck, no matter what the PCM Code is! The only issue you might run into is if you put a DPC-422 PCM from an F-550 (with 5.13 gears!) with VXY4 PCM Code into your F250 with 3.73 gears, the transmission shift points might not quite be where you need them.

No problem. We can program any DPC with any PCM Code.

 

Answers, real answers and knowledge = Awesomeness

 

 

I am sending mine to them today. Fingers crossed

 

 

Who did you order from?

Thanks Stewart and Pirate. Just wanted to reconfirm. I sent my PCM to him today. Hopefully he can fix it.
