IDM TESTING & REPAIR

Swamp's can now provide complete testing and repair of 7.3L Power Stroke Injector Driver Modules, and testing of PCM's (Powertrain Control Modules).

Our test bench consists of a complete engine wiring harness modified with two PCM connectors (one for 1994-1997 PCM's and the other for 1999-2003 units), an IDM connector, 8 injectors and a cam trigger wheel with a CPS mounted to a variable speed motor allows testing up to 6000 RPM.

A control box allows simulating any sensor input to the PCM--EOT, EBP, IAT, MAT, BARO, MAP, TPS, etc and a custom circuit provides an ICP "feedback" signal  to the PCM proportional to the IPR duty cycle.

A cutout box allows disabling any injector, and a breakout box allows instant access to any signal into or out of the PCM or IDM, and the wiring harness also has the ODB-II plug for connecting a diagnostic scan tool.

Every IDM or PCM purchased from us has been run on the test bench.

The bench is also useful for hacking / testing  mods to the PCM code. ;)
