Your loom will NOT plug into a K6, a patch lead can be made to enable this, with the ecu you get the K6 fitting for the end of the loom to fit into the ecu, so can always "replug" your loom with the supplied connector, you also get the software disc that cna be used on lappy etc, and lead.
The coilpack will not be an issue, at time of ordering discuss what you want, emerald will NOT send out any ecu without a base map, the closest one they have to your spec, just mention it is on coilpack, using 36-1(which is 90degrees btdc +/- 35 degrees), though you can adjust settings yourself, eg tps alignment takes a few seconds when installing no measuring no nothing, just press pedal fully click ok on laptop!!
