HELP please!!! K20a2 swap with PRA ecu and narrowband o2

[Wrenneth]

Hi,

Im having some trouble with my EG K20a2 swap as i have begon the wiring.

My setup:
-K20a2 uk spec
-PRA ecu with immobilizer deleted (Kpro is coming very soon)
-UK engine harness
-o2 narrowband sensors
-K-Tuned conversion harness for EG

Now the problem that i have is that the K-tuned conversion harnass is for US spec that use wideband o2 sensor and im using narrowband UK spec sensor.

Does someone nows how to wire up the narrowband sensors to the K-tuned conversion ?

I probably have to de-pin wires out of the conversion harness from the o2 sensor and re-pin them to the right connection just have to now where to pin them...

A diagram or pictures from the wires converted from someone driving same setup would be very nice

Thanks in advance

You should contact the manufacturer of the harness for assistance with rewiring an o2 sensor.

Hello, I am in the exact same situation, did you work this out and what did you have to do to get it to run the narrowband sensor?

If everything is correct: engine and conversion harness, ecu , sensor and grounds the "work around" is in the post below,

I know its a long time ago but handy to have a question with an answer/solution,

Hi Hoffy,

Thanks for your reply. Problem is the conversion harness is for PRB & wideband, I have a euro motor, PRA ECU and narrowband sensors & am struggling finding diagrams to wire it up correctly. I've got an AEM wideband hooked up to my k-pro and the car is massively leaning out.

Currently with my datalog O2 sensor is reading 0.00 - 0.10v max, whereas the S02 is reading 4.08v constantly and not changing, could the K-Pro be getting the wrong lambda signals? I will try swapping the sensor cables around incase I've got them mixed up and see what happens.
