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.

In addition to DTOC normal rebuild process, the High-Voltage High-Current units get two additional tweaks. The first step increases the output voltage to the injectors from 110 volts to 140 volts. The second step increases the current output by about 20%. This activates the injector quicker, holds it on (poppet valve open) more firmly, and keeps it on just a bit longer. The result is snappier acceleration and a more responsive truck.

After the rebuilding and modifying is done, they run each IDM through a 20 point test on the test bench, and then run it continuously for 30 minutes at 3000 RPM and 3.0 milliseconds of injector pulse width which is longer and harder than you could ever run a truck in real life. When it passes this test, then it is ready to sell.

DTOC has been doing the high-voltage mod since 2004, and invented the high-current mod in 2008, and haven't seen any negative side effects to either the injectors or the IDM in this time.
