It WILL be cheaper and faster for you to go to a standalone

Thanks fella's, I realised what I needed in general but I was hoping for a more specific answer from someone that may have direct experience with these ECU's.
Going standalone is my prefered option TBH but on a car that has two ECU's (DME & EWS) with every system CAN BUS controlled is not as easy as you think, even simple things like the air con, electric memory seats, power steering even the radio are all controlled by the ECU so I have no idea what will work if the ECU doesnt see that the car is running? The PAS for example may not work as the ECU will not activate it until it see's the engine running, this could be a simple as a voltage trigger or it may be RPM triggered (CPS signal) who knows?!
If everything worked relatively easily then I would just MS3 it, but I don't want to be left with half my car systems down and the headache of figuring out how to fool the ECU into thinking it's all ok.
Although this may be the way I end up going... I can unplug things one at a time and see what still works in the car!
