The Old De-Cat Question
« on: February 05, 2019, 11:38:53 am »
so assuming you upgrade the DP and go Cat-Less....what do you do with the O2 sensors ?
surely this will ping the Engine management light on ?
noticed some of the upgraded Dp's have the holes in for the O2 sensors to be screwed into...

Sensors need refitting, appropriate mapping will disable the cat efficiency error that causes the EML. Do not leave the lambda sensors off or unplugged

Lambda sensors do an awful lot more than just check thee is a catalytic converter fitted and working :signLOL:
