On the alloy Mono subframe for the 748R the 1.6M Ecu sits across the back of it, rotated 90 degress from the plain in which it sits on the BP subframe, this means the multiway connector is slightly futher back, a bit of careful rerouting of the injection harness can be done to allow it to cope with this extra distance, although repositioning of the air temp sensor or lengthening its 2 wires may be required.
I haven't done it myself but I know Karl the Oxon/Berks RO has done it
