hi. ive done this conversion recently....2.0 blacktop into a mk4 fez. im running megasquirt and didnt really come into many issues. and the beauty is its very easy to map. done most of the boring maping myself, as i drove around with a wideband, then visit a dyno to sort the high end stuff and build some torque into the map.

However, i probably couldnt be further away from you as im south east! ha
