Hondata

One question I have is if I am getting a no activity detected code, how is the live feed on my datalog showing my afr changing as I drive? Is that not picking it up from the upstream sensor?

The vehicle is a 2002 RSX Type-S. The ECU installed in the car is a PRB type with the Hondata KPro board. The only modification done to the car is an AEM v2 short Ram air intake. The only thing I did before installing the new ecu and uploading the Kal was adding additional grounds in my engine bay.

I don't really have another vehicle to test it on. But I'm just wondering how would I have a wiring issue if I was not getting the code prior to installing the ecu? Do you mean the o2 sensor wiring is faulty or something else?

The number under the Honda Sticker which says K-Pro4 on it reads "47759". Is that the one?

So I recently bought my KPro V4. Prior to putting the KPro'd ECU in I did not have this P0134 code (O2 Sensor Circuit No Activity Detected). I am running the stock calibration for the k20a2 with no changes.

When this code is on I am not able to datalog. I am able to datalog and record but no values ...
