EMERALD ecu can be set up with your own map, but will be supplied FOC with base map if you ask.
KARL the man who designed these ECU's, and works for emerald with DAVE WALKER knows his stuff.
These ecus also have a host of useful features including switch selectable different maps, map interpolation, and a load more.
They plug straight into all K SERIES engines(looms), rovers, lotus etc.
They can also use a multitude of different sensor inputs, and fire coilpacks direct, use either vaux or ford trigger patterns, so all sensors dirt cheap as well.
