decat pipe has put eml light on. flagging o2 sensor. ideas???

[nickfantastic]

hey first post so bare with me.
i recentley bought a 150 fr petrol. i decided to put a decat pipe on before i got my remap however it has put my eml light on. i code read the car and its flagging the downstream o2 sensor reading a weak catalyst reading.
does anybody know of a upgraded or tuned o2 sensor on the market or if this problem will go away with my remap.
help much appreciated. thanks guys

Decating a petrol will bring up these faults.... as the ecu is looking for readings from the o2 sensors to calbrate fueling etc....

When you come to M.O.T time I think your going to require putting the cat back on or else your going to fail the emmisioms test.

Personally I'd of gone for a 100 or 200 cell cat. (£0.02)

But if you ask your remapper to map out the o2 sensor (think revo do this) then the problem may go away.

think i had my sensor mapped out when i had revo stage 2 put on, the guy said thats all they do really and tweak the settings slightly too. I done the settings afterwards anyways as i have an sps3. I have had no cel lights come up at all though so all is good
