A common problem with after market downpipes and cats is that you eventually get an error code associated with the O2 sensor efficiency or the readiness code never gets set. The Wayne's Angle Block and spark plug anti-foulers are a fix that sometimes works.

Has anyone figured out how to force the readiness or avoided DTCs using Unisettings or Lemmiwinks? Specifically, can adjusting the value of Channel 06 (Lambda Regulation) up or down force readiness or avoid DTCs?

 

i asked this very question on many forums about 6 months ago and got no answer that was of any help lol all suggested waynes angle block...

 

You either have to space out the sensor or have the chip tuner write in a code that eliminates the cel from coming on.

 

I think that's what Revo does (or did).

 

Any idea which O2 sensor is affected by the Channel 06 settings? Which sensor is call the narrow-band sensor?

 

i got my wayne's angled blockfor $36 shipped


didn't know that machined little block cost so much

 

I have wayne's angle block already, but still got a P1176 code yesterday.

 

^ really, the block threw a code? how long have you had it? testpipe?

also, i know about 1/4 of the maganflow hi-flow cats throw CELs

 

Probably about 10 days. Not a testpipe, but 42dd 3" dp with hi-flo cat.

 

Both front and back are nbo2's on nonVVT cars and just the rears are narrowband on VVT cars. There is a lemmiwinks guide on vortex in the 1.8t section that break down what every channel does
