So for about £850 on top of the price of buying a L8, it'll run a coilpack, closed loop fueling and if you connect a laptop show the output of the Monitor software.

On top of that, I'd still need someone to map the engine at a cost upwards of, let's say, £300.

I don't map cars, so I'm not interested in how easy it is to load or alter the map, or protect it from being copied.

What are the advantages of this over a L8 with say the MSD coilpack board and closed loop fueling conversion ?

I don't want to appear negative, but it does seem expensive compared with what is currently available.
