Lambda sensor question ???

don't no y it's upside down

don't no y it's upside down

you want us to brake our necks?
next time use op-com recording option. it will record all the CU readings.

Op com is insalled on my sons laptop .as mine is nackerd . I uce my mobile for all this kind off stuff

Hi guys, I wonder is there any chance to turn off the second Lambda sensor in my z22se using op-com?
I'm asking because I'd like to decat my exhaust definetly and don't get check engine light

Or should I take a chance and use original Tech2

 

[Daz86]

Just buy a lambda cheater job done

Thanks for reply.

Are u SURE, it will prevent me from yellow control light ?
I was looking for this way of sorting tis out, but found that it sometimes doesn't work.
Software cut should be perfect solution. All I'm asking, what tool will I need for this

just fit an elbow and move the rear sensor out the gas flow

 

[Daz86]

Yes I'm sure you can even get a blank plate for the lambda and just tuck the sensor up in the engine bay and the ecu will think all is good and not put the light on . That is with it still connected .

You will need a 22mm lambda socket or a 22mm spanner those things don't normally come out easy and are tight

I wonder, what difference does it make, if you fit this elbow? I mean the theory?
p.s. My lambdas works fine atm.

 

[Daz86]

All it does is move the sensor out the way of the exhaust gas and restricts the amount to the sensor

if you remove the main cat like I did Then with out the elbow both sensors get the same reading putting the lamp on

needs to be plugged I or you will het heat error and then eml for no sensor elbow is the best option I've never used a cheater so cant sa
and with out it in the gas flow there would be eml

All right, its obvious.
But what impact it leaves on lambda graph, ECU and engine behaviour?

 

[evocarlos]

non the rear sensor is for catalyst check the front sensor is the control sensor

 

[Dave Gilbert]

My second lambda is deleted out the ecu on my z22se vectra c and disconnected from the loom (still in the exhaust as i havnt got a blank yet)


Buttttttt. My z22se is running on trionic 8 engine management system so not sure if u could delete. But the angle joby does the job

 

[Johnss]

All right, that's cool!
