Wideband after cats reading
Hello,
I would like to know how much leaner does a wideband read if it is after cats.
I put mine (Dynojet) in the merger of the Y pipe. Cats are Random Tech
The wideband is reading a bit lean but I get no KR.
Spark plugs look good too.
Could it be .5 leaner VS before cats? Anyone with experience in such matters.
Thanks,
Mark

It could be argued that the further back you monitor A/F, the more accurate, because pressure (exhaust backpressure) skews a wideband's reading by a few points (10ths).
