well im pretty sure it wont remove the fc. i had 1 of these and needed an fcd as well. even though it uses the same feed from the map sensor, u need to wire up a fcd after the safc if i remember correctly? u can set it up urself with wideband if ur confident but recommend goin on rollers. advise richard brothers in redroof, cost bout £150 but they have done a few of em with this setup
