Hondata

I have a 2004 Honda civic with a stick tune, the primary O2 sensor shows no input to the ECU. I have replaced the O2 sensor with no results. I have verified the there is good continuity from the O2 sensor to the ECU as well as voltage from the O2 sensor. Car obviously runs poor as the A/F does not properly adjust and runs Rick with no Primary O2 input

Have you moved the wires as it says on the website: https://hondata.com/products/kpro/kpro- ... uage=en-gb

Yes wires are moved per the set up on the website

Show me exactly what wires you have moved and where.

Post your calibration as well as a datalog showing the issue.

Calibration

Pic of A/F ratio

Voltage on connector A pin 6, it does change if you press the throttle.

You have not posted the calibration and a datalog showing the issue. Screenshots do not give us any info.

Hopefully this is what you need.

I hope this is the Cal data you need (I feel computer illiterate)

You should follow the trouble shooting steps in the factory service manual for the P0134 error you are getting. You also need to address the other errors you are getting.

The steps being… replacing the O2 sensor, which has been done to no change. I verified that the O2 sensor has a voltage to the ECU (as shown in the picture with the multi meter) next step replace the ECU?

You need to try the ECU in a known working vehicle that can use a K-Pro. This will tell you immediately if the issue is with the vehicle or ECU. Our dealers should be able to help you test this in another vehicle.
