Have fitted induction kit to Bravo 1.2, ummm dont do it, it has screwed up the ecu. Might as well shove it up my arse for all the 'improvements' it claims!
I'm not sure if this works, as mine was fine after i fitted it to my 1.6 elx, but i have been told that you should disconnect your battery overnight, so your ECU loses its settings, and then it will have to re-educate its self, correct to your car with induction kit!
Allan's right, disconnect the battery for around 10 mins and then re-connect. Start the car and leave it running for around 2-3 mins at idle then start applying various levels of revs.
After around 10 mins, then take the car for a short drive at various speeds using different engine revs, and the ecu should then have re-set itself.
