Tom Starlet Posted December 22, 2005 Share Posted December 22, 2005 hey people.im looking to get my car de catted,but i have heard some people say that when you do this you may need to have the car re mapped.dont know if this is right and wondered if anyone new for definate.if i will need it re mapped do you think it is worth while de-catting for the power increase i will get?cheers tom Quote Link to post Share on other sites
lobotomy Posted December 22, 2005 Share Posted December 22, 2005 Assuming you're driving a GT or Glanza you shouldn't need to get your car remapped. The standard ECU should be able to adjust itself enough to compensate for the increased flow.You may however start to hit fuel cut if you're coupling the decat with an aftermarket exhaust. To get around this you'll need and FCD (Fuel Cut Defencer) - Or what you may have been hearing; a remapped ECU chip Quote Link to post Share on other sites
gaz Posted December 22, 2005 Share Posted December 22, 2005 ive read but want confirmation that decats are allowed in the uk on GT's and they cant fail an M.O.T with a decat on GT. can somone confirm? Quote Link to post Share on other sites
ian Posted December 22, 2005 Share Posted December 22, 2005 all cars made after 1992 have to have a cat in britain.....its the law, if a car was made before that time it can have a de cat made. its all to do with the emittions test in the m.o.t ;) Quote Link to post Share on other sites
gaz Posted December 22, 2005 Share Posted December 22, 2005 but apparently where they dont need one in japan or something like that they dont need one here as it isnt registered as a uk vehicle Quote Link to post Share on other sites
leon Posted December 22, 2005 Share Posted December 22, 2005 we dont need one because it aint registerd in th test book! Quote Link to post Share on other sites
gaz Posted December 22, 2005 Share Posted December 22, 2005 see this is why i get confused, lol Quote Link to post Share on other sites
DAN_GTT Posted December 22, 2005 Share Posted December 22, 2005 Wrong!M.O.T's have all gone over to a computerised system now and they dont have any info on the imported cars,so as default it comes up as a non cat test!It will pass if you have a decat or not ;) Quote Link to post Share on other sites
DAN_GTT Posted December 22, 2005 Share Posted December 22, 2005 Yeah the M.O.T's have only just gone over to the new system, so from now on it applys lol ;) Quote Link to post Share on other sites
gaz Posted December 22, 2005 Share Posted December 22, 2005 yeah dans pretty solid with his mot info. Quote Link to post Share on other sites
Tom Starlet Posted December 22, 2005 Author Share Posted December 22, 2005 nice one lads.i think i will start to get a few prices together.dont think it will cost too much though.can any one tell me if i can expect any noticable performance increase?have been told you can get between 5-10 bhp.

gaz Posted December 23, 2005 Share Posted December 23, 2005 for a decat?? probably a few bhp, depends if you mean with a full system then it should be over 10bhp Quote Link to post Share on other sites
Tom Starlet Posted December 23, 2005 Author Share Posted December 23, 2005 have got a standard system at the mo but have got the blitz n.you.r back box.think if i do get it done will get the full system while i am there.cheers for the advise.tom Quote Link to post Share on other sites
BlackTarw Posted December 23, 2005 Share Posted December 23, 2005 with a decat you'll find it willing to rev alot easier and probably come on boost a bit sooner. Quote Link to post Share on other sites
DAN_GTT Posted December 23, 2005 Share Posted December 23, 2005 Yeah spool up is much much quicker,with the full system i found that it has taken away alot of the lag. Its proven you can gain upto 16 bhp with a full system and decat ;) Quote Link to post Share on other sites
