Sirs please can you help me, i have a 1999 Rolls Royce Seraph which has the BMW M73 engine in it and i have a crank no start situation, RR has encrypted the ECU so that BMW mechanics cant log on with INPA, only RR mechanics can with RR equipment which is no longer available, i would like to throw away the ECUs and replace with your units to get this damm thing running. How do i purchase these from you and is it a "plug and play" situation?

In theory yes we could run the M73 engine.

In reality, OH BOY is that a BIG challenge.

There are a lot of systems on the car that will depend on information from the ECU, the dashboard, the transmission, the ABS and all of the entertainment systems.
This is far from an easy car to do this on and there is going to be basically no information available to help with it.

If you try to do it then you could be looking at thousands of hours of work and I doubt anyone here will be able to help much with the systems on a Rolls Royce.
There is also the issue that right now it is broken in an unknown way, this could well be a problem that makes it extremely frustrating to get working on rusEFI. It is never wise to make a non-running car your first attempt at fitting and tuning a stand alone ECU.

It might end up a lot cheaper and much less pain to take it to the RR dealer and have the diagnostic done.

Where are you located?

Some of our units are "plug in" but neither are "and play" really. While we can have the _engine_ running we've made no investment into ECU<>TCU integration.
