You'll just have to wait and see, dread.

... Some things do sound too good to be true, but I aint putting up pics in the present state it's in.

[porkkis]

MC with 1 knock sensor has a C/R of 7.8:1
and MC with 2 sensors has 8.4:1
and 1B has 8.6:1

So only these differences give different basic characteristics and I would not mix the ECU's because of different ignition timings needed...

Also the 1B is a non catalyst engine without a lambda probe and both MC versions have the cats and the o2 sensor.

Thanks Porkkis, that's just the information I was after.
