4.5L duramax

Hi Guys,

I have been given the opportunity to purchase a 4.5L duramax engine with loom and ECU at a really good price.

Is there much information available for these things as far as wiring and tuning? Any idea what ECU they use? Or could say a LML ECU be adapted to work with the engine.

My concern is buying an engine that will be essentially useless if we cant get the ECU to operate, And because the engine essentially doesnt exist there is zero information about it, Unless a GM engineer happens to have something to share

Thanks
