bought this a while back with the intentions of putting this in the bonus, standard ofab ecu and loom intergrated with what i believe to be a mk4 efi loom complete with fuse box relays etc, also has an alarm and fob, its still in the box from when i had it delivered, so never used it. great for a cheapish upgrade from mfi,or converting to turbo transplant £100 postage to be added
