I have a 03 wrx, Which I fully decatted two weeks ago. I was worried about over boost and hitting fuel cut with the de cat. I have found the scoob is fine. It boosts a bit more but only to about 1.2 bar.I think this is the best mod I have had done to date. But. You will need a CEL fix.

If  you do it, You will think why didnt I do this months ago.

Thanks for the info Graham .Im new to all this .Not meaning to sound stupid but whats a cell fix ??[:$]

 

Its a CEL fix. Not cell. Ok Your scoob has sensors in the exhaust system. If you remove the cat in the down pipe the scoob will show a check engine light. (CEL). Its  the ecu telling you that there is a prob with the cat. Well we know this because the cat  has been removed. So you will need a CEL fix to turn the check engine light off. You can run with it on, But if you get another prob with the engine you will not know because your light is already on.

Thanks mate ... Has anyone else had problems with the cel fix on a wrx .If you have how did you solve it or get around it ?How much was it ?Has it got to be done when the down pipe is being fitted ?Will the car run properly without it being done Straight away? Where can i get this done local to Dartford kent ?

micky.

you will eventually need the CEL fix. to start with you may  get away with it. mine took around 4-6 weeks before it brought the light up.

scoobyworld, scooby clinic etc. sell these units. also you can get them from barretts motorsport in canterbury.

takes about an hour to fit, will req soldering into your existing loom near the ECU.

Thanks dean i know about the cel fix thing .But ive been told that when the light comes on the car goes to safe mode I.e cuts the power down ect . The thing is if we are going on the RBMR i dont want this miles away from home .Where did you get yours done ? OR do you know someone who could do it . 

  Sorry to be a pain in the arse .[;)]
