i think i have some bad 02 sensor in the rear (have SS race cats installed) so i think i'll be needing longer wired sensors (since i lengthened mine myself) so does anyone have the part numebrs for the EURO 02 sensors?

were of a different calibration than the US spec 02 sensors. Are you getting a SES light?? Dave

going to reload my software to see if it removes car from limp mode... Clearing the SES or faults doens't remove the limp mode..

CAr got a attitude when i put all the 02's on the header.. so i put them back on post cat and still won't get out of limp mode even when i clear the faults..

with SS, how can longer than stock not help ? JOE

to read actual 02 sensor readings. See how fast they react, if they move slowly or stuck at a certain reading they are bad. One other thing, if its a bad rear 02 sensor you shouldn't be getting a limp home mode. The rear 02 sensors are for diagnostics of the cats, they are not a gross adjuster like the front 02 sensors. Thats why the race shark injector works with or without the cats. Dave

to another m3 today.. (M) JOE

and my 02 senors are all flat lined.. this tells me that the limp mode made them closed looped.. Where i screwed up is that i cleared the ECU before i wrote down all teh faults before i went into limp mode, so now i know the dealer is going to have a hell of a time figuring out why my car went into limp mode.. I guess tehy could clear it out of limp mode, let it trip again and see what is going on.. but i am sure its not a bad 02 anymore.. something else happened..

CAr goes to dealer to let them play with it.. sucks for them...

to limp mode.. To dealer she goes..JOE

the header and melted (m) JOE

and then flew the heater control circuit for the sensors.. THis fuse made the car go into limp mode.

Required fixing and re-routing the wires and all set..

lession.. Shorting 02's sensors will blow a fuse, then make the car go into limp mode...
