CEL: P0421 (Warm Up Catalyst)
Since the weather has got colder this CEL seems to be a reoccouring feature with my Catted CP-E DP Fitted
Apparently this is more or less an indicator stating that the Catalyst is not efficient/effective/as good as(altho that is debatable) the factory Cat.
Basically the simplest means of a resolution to this CEL is purchasing a O2 Sensor Extender Sleve to remove the Secondary Sensor from the Exhaust Tract Slightly.
What I need to find out is where to find one do anyone in Aussie have them off the shelf(no one locally seems to know what they are)
I am tempted to make my own but just need the time to find out Thread Sizes and find various Fluid/Oil/Air Fittings that will allow me to make this.
I realise this is normally the solution for the Catless DP but the Highflow cat doesn't necessarily sit well with the Finiky ECU that does all the thinking for the MZR.
Does any one have Dimentions and thread sizes i could make use of to weld up my own extender rig or have any suggestions as to where i could buy a resonably inexpensive O2 Sensor Extender
Peace out you lol-cats
