View Full Version : XB ECM compatibility

02-07-2013, 08:35 PM
I have a 2009 XB 12Ss. Stock ECM and exhaust. DDFI3 system.

I would like to know if I can swap out the ecm with a 2006 DDFI2 race ecm, provided I swap in a perf exhaust and filter? Anyone try this swap yet? Don't want to break something.

Hoping someone here can shed some light on this for me. Thanks.

What are the differences betwen ddfi2 and ddfi3 though? I assume the plugs are the same. But what makes them non compatible? Different sensors? The timing and all of the maps should be the same...theoretically.....

Yes different sensors. ddfi 2 runs off cam position sensor and ddfi 3 uses crank position sensor to tell engine phase. Throttle body is different as well as other things I can't remember off top of my head.
