Primairy 02 sensor error code after Kpro install

[Vtequila]

Hi i am Jochem from Holland and driving a JDM Honda Integra Type-R 2002

I recently installed my Kpro PRB ECU '02 about 2-3 weeks ago and uploaded the next calibration:

Itr-k20a

This calibration gives me the best A/F ratio (around 14,5) with the current modifications I have on the ITR. The problem is, that since I drive with Kpro it regularly emits an error code. This is the Primairy oxygen sensor code, still need to write it down because a friend of mine helps me out with his laptop. I could order a new lamda sensor (Primairy) right away but if this does not correct the problem and still keeps giving error codes then im still down with it..

I can tell that when I start the engine the Primairy 02 sensor starts recording after 15 seconds, from this point I can see voltage in Kmanager, is this normal or do I have a semi-wide-defective lambda sensor? After checking out various forums and topics I still didn't found my original problem. I am looking for clarity before I am sure that I should go buy this expensive 02 sensor.

Who has experienced this before and can tell me what I should do?

Regards,
Jochem

Without the error code, the calibrations and a datalog showing the problem it is nearly impossible to speculate.

I will have the error code by tonight and saved a cal + kdl on my computer.

A friend of mine helped me out with his laptop and he has the error code(s) saved up on his laptop.

Update, found the errorcode :

"P0134 A/F fuel ratio (Sensor 1) no activity detected"

Tonight I went out testing with an OEM ecu to see if I would get any error code(s). Drove for like 20+ minutes and didnt got any..

So this problem remains a mystery for me. Or is the Kpro more accurate than the OEM ecu with error codes when it sees that the lamda sensor is almost defect ?

You still have not posted the calibration and a datalog showing the problem.

please post the calibrations on the forum and not links to offsite hosts.

sorry ;)

Everything looks fine in that datalog and it shows no errors.

Im thinking of just renewing the 02 sensor, would be the best imo.

Problem is solved after I bought a new lambda sensor and fitted it.
