I had a motec M800 and MDD and a few other items, I did not like the window frame extrusion case held together with self tapper screws, nor did I like the very basic PCB construction that in the event of outside systems being screwed would melt a track if the polarity was scewed, all in all I thought it was a very over hyped and over priced system, and the pay to play code enebles are nothing but an outright scam.
I replaced it with a Pectel MQ12
It has no pay to play features, comes with 2 GB internal logging, the software is on another planet, build quality is amazing.
The SQ6M12 would be similar except you dont get the all in one logging ability thus you would need to keep your Dash.
If it were me I would E-bay the Motec Dash, and get the Pectel/Cosworth ICD lite version and a MQ12 ECU, simpler, lighter, better, no need for external spark boxes, no rip off codes and not a window frame extrusion in site or any self tappers holding it all together
