Caterpillar ECM
This ECM is build with only one goal.
Maximise your engine performance and this ECM platform will support your project able to run far more RPM than your engine can handle.
What makes this ECM unique? Two things:
The main controller allows for writing your own controls from fuel metering to mutable control systems from boost or wastegate control to launch control options if you want to run boost on the starting line or want a two step launch control, controlling engine power @ the start it can all be done.
The Injector drivers are build to industrial standards and use power recovery from the injector coils in a way that not only we have extreme low power consumption but our drivers store the energy making it possible to run hi RPM on the engine and still have the ability to fire the injector in rapid succession without dropping power for the boost phase of the injector coils so peak current is consisted giving the guarantee that injector timing and metering remains within injector specification.
What will the future hold.
Some of our US and Canadian customers are in the proses of converting there CAT C series engine from pump injector to Commonrail and our Caterpillar ECM will support multiple fuelpump control as well.

DI Injector solenoid driver specifications:
The INJ drivers are build to industrial standards and use power recovery from the injector coils in a way that not only we have extreme low power consumption but our drivers store the energy making it possible to run hi RPM on the engine and still have the ability to fire the injector in rapid succession without dropping power for the boost phase of the injector coils so peak current is consisted giving the guarantee that injector timing and metering remains within injector specification. Also every DI injector driver output has his own hi side driver stage and this will make it possible to fire the injector independent without limitations to timing and duration. Most automotive DI injector drivers share 2 up to 4 injector outputs per hi side driver meaning only one of these injector outputs can be active @ the time giving complications when pilot and post injections are needed.
