you can try swapping your ECU's ... but it can only be a wiring or a sensor problem

Hi,

we swapped yesterday the ECU and it still shows Lambda 1 / Ive transfered also the ECU Files from my working ECU to the other and no chance :(

Lambda shows still only 1 ..... Please guys give me a last hope :P

Must be something with the wiring.
Maybe no supply on the Sensor?

One last hope:

2. on my Log all values are moving except of the AFR/Lambda, my this help :)

1) wiring problem

2) power supply issue

3) damage sensor

No readings at all from the sensor.

1) Wiring problem it can not be, because it works with my other EMU
2) Sensor problem, the same
3) Power Supy, the same

IT must be something with the EMU / U know mybe how i can check this ?

I meant that i swapped the "BAD EMU" to my other car, where everything is working perfect.

And it still dont work

So it must be something "INSIDE" the EMU :/

Ok understand, there may be a internal malfunction, the only way to confirm damage unit, is to send it back.
