Hondata

I flashed the base calibration k20a2-civictyper-tuned.kal, which has always worked properly. The O2 voltage was correct, and lambda/AFR control was functioning. I’ve recorded the current behavior with the wideband and narrowband sensor and will attach it.

Yeah, I know that with this calibration you don’t see any O2 voltage. Tomorrow I’m going to flash k20a2-civictyper-tuned.kal from the Hondata list. With that one, the O2 sensor always showed the correct values and lambda control was working as well.

Thank you for your quick response. I’ve attached the wideband sensor calibration and hope the issue is related to the map.

It´s a Lotus Elise with K20A2 engine and the ECU number is 37820-PRA-E2

<t>"Hello,<br/>
I am using a Hondata KPro V4. A year ago, my car was professionally tuned using a PLX wideband sensor. Now, I need to pass the German 'TÜV' inspection (equivalent to MOT in the UK or Safety/Emissions in the US). For their diagnostic software to pass the car, they need to see a ...

Excuse me for the mistake.
For wideband, Is this the right connection, or connect 0-5V to ELD pin?
Thanks

Hi again,
I took some screenshots to show you how PLX and Hondata are connected and configured. At sensor picture you'll see at O2 a frozen value 4,06V.

I will make some pictures as soon as possible that you see what I mean.

At time I have output PLX 0-5V connection to ECU analog 0. There I have edit conversion row, as seen on Hondata K-Series ECU Help.http://www.hondata.com/help/kmanager/index.html?analog_inputs.htm.
Subsequently I have completion the input box "Details" as shown.
The only one different I see, in the ...

Just sounds.
And what about the frozen O2 value in sensor window. Is it normal? Where could I read out the actual Volt value?
Thanks

OK.
But is my wiring right for this?
I have connect 0-5V analogue output from PLX to ECU like http://www.hondata.com/help/kmanager/analog_inputs.htm.
Lambda is working and I measure 2,3V at the PLX output. One thing irritates me. Why there is not a voltage signal at O2 sensor spent in the ECU ...

I have problems with car inspections "TÜV in German". I have install a PLX Wideband and it works fine but for the inspection it must be the original narrowband signal which will be read out from OBD2 Controller. Is it possible to leave PLX inside and simulate the narrowband signal?
Thanks

You mean one of the seven analog pins inside the ECU?
Thanks

Hi,
I have a Kpro V4 ECU for aK20a2 and want use a PLX wideband lambda. Short question, is it possible?
Thanks

Thanks
Shall I cut the remaining OBD wiring from Lotus ECU like PIN 65,79 etc.
Or it doesn't matter and I could save work
