Kmanager version - 4.3.4.0
ECU part # 37820-PRB-A05
ECU serial # 2068-506299 0C01
I hope that's the information you need. I'm not so hot with the computers. Lol.
I'm going back to the tuner this weekend to get the car retuned on the dyno (I replaced my Skunk2 cams with the stock cams on the advice of the engine builder, InlinePro). But aside from more power, I'm hoping for better fuel economy. I'm sucking fuel like no tomorrow and I suspect it's due to the fact that, as far as I can tell, the KPro can't read the wideband. Both on the app and hooked up to the Kmanager the AFR reading is a static 14.7 at all times. Clearly this is not right. I have both factory o2 sensors connected to the factory wiring harness and in the stock locations. I also have an Innovate Motorsports MTX-L Plus installed in front of the cat. Here are some pictures to show how the gauge is wired into the ecu (analog side). Based on what I see in the software, I don't think it has all the info to read it? Please help Thanks.

Re: kpro not reading the wideband
Under 'Parameters' -> 'Closed Loop' change the 'Closed Loop Operation' from Narrowband to External Wideband.
Next when I look at the voltage on the kpro analog input it is not what I'd expect from a wideband, so I would check the wideband voltage output settings.

Re: kpro not reading the wideband
You intake temps seems very low (~18°F).
I'm not sure where you live but if you are still running the stock S2000 IAT sensor this could be another reason for your bad fuel economy.

Re: kpro not reading the wideband
Yeah I'm in Tennessee and the temps for iat are always low. Is that a programming change needed or a different sensor? If so, which one?
Re: kpro not reading the wideband
We recommend changing the sensor:
•IAT sensor 37880-P05-A00 (not required, but stock IAT will read about 30 degrees hotter)
•IAT sensor 37880-P05-A00 (not required, but stock IAT will read about 30 degrees hotter)

Re: kpro not reading the wideband
Funny thing... I realized that I actually forgot to swap out the new iat sensor (that came with the swap kit) when I got the engine back. So I just installed the new one in place of the stock one. Now the temps read what I expect (slightly hotter than the ambient temp). But I thought stock was supposed to read hotter and the new one colder? Seems like my stock read way cold and the new one hotter???
Re: kpro not reading the wideband
Yeah I think Hondata might got it the other way round? I've seen the same thing on another car (too cold reading on stock sensor).
