Surely Cossie and FRST ECU's would fall foul of the same problem, as they both require MAS/MAP sensors... ?!?! You'd have to use a NA only setup I presume..??
Isn't it a 2D one you need.. Just speed and TPS.. where-as the Zetec one you've got is probably a 3D one with Speed, TPS and Load... and with TB's (without an airbox) you can't measure the load as a whole... ?!?!?! Not that I profess to know that much, i'm only guessing..
