i have a zeitronix zt2 and when i start my car its reading 21 solid..

what the hell is going on. one thing, i mounted it right on the end of the open downpipe, like 3" from where the exhausts exits.

anyone know what the hell is going on?

does the car need to be warmed up totally or what?

 

1.) There is about a one minute warmup time
2.) Taht close to the atmosphere the sensor may be contaminated by fresh oxygen. That's why exhuast leaks read lean on a wideband too.
3.) 02 sensor maybe going out.

 

hrm maybe i didnt warm it up enough. or its to close to the end of the pipe..

its brand new so im ruling out #3

 

i have to let my fjo warm up.

 

let it warm up...and in my oepn dp...its still 10" away from the opening...your prob containmainitng the source w/ o2 like others have mentioned

 

yep it was to close to the exit. thanks guys.
