Hello,

This is my first tune with K-pro and everything is fine the only issue is that i have this error code and i tried a lot of things and always show up again and again.

I'm using a Innovate DB kit.
I'm running open loop because i'm tuning the map.
I have the wideband signal in the ELD pin.
PRA ECU. EDM K20A2

Any clue?

Thanks for the support.

PO132 O2 Circuit High Voltage (Bank 1, Sensor 1)....I'm assuning this is the code your reffering to. Noticed you said your tuning it in CLOSED loop. Tune it OPEN loop so that your ecu isnt trying to compensate for your fuel values. Good luck and happy tuning

Thanks for the reply.

Sorry my mistake i'm tuning in open loop off course.
I'm was thinking in a possibility since this ECU is a PRA maybe the problem is only when i'm tuning (open loop).

I will have a try in closed loop since the map is better now to see what's happen.

Thanks

Regards

I have this error code too. It throws a check light after a few mins driving.
I think the issue is with the Hasport wiring harness.
I've replaced the OEM sensor with a new one but still the same.

Also, the AFR in KManager stays at 8.5.

Please let me know how you get on.

What i made to solve the issue was:

After i tuned all the maps:

Enable closed loop at only ~21kpa
Enable secondary oxygen sensor
Enable the use of secondary o2 sensor for closed loop operation

Try this and your problem should be gone ;)

Regards

I'm using the K20 engine in a EG Civic chassis so i don't use the second O2 sensor.

Ah!
