7.3 IDM Rebuild Stock Service (1994.5-2003 )

Diesel Technology of Chattanooga can rebuild your 7.3 Injector Driver Module back to like-new/factory condition. 

Note that whereas they often sell good used PCM's, as far as they are concerned there are no good used IDM's. Even if someone sends back a core that is in perfect working condition, it still gets rebuilt by replacing about 20 components that are possible failure points before it goes back out the door.

After the rebuild, 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.

In addition to Diesel Technology's normal rebuild process, their 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.

Diesel Technology of Chattanooga 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.
