Lambda o2 sensor problem k-pro
Hi guys,
I've a dc2 K series conversion and i have bought a denso stock replacement o2 sensor which i hooked up to the K-PRO. Now the car is running fine but when i monitor the stats on the laptop, the air to fuel ratio command is at the right values (between 13.2&14.9 depending on load) but the actual measured lambda value is reading between 20-30:1 which is very lean.Its strange because the exhaust fumes smell rich and im not getting any knocking which i'ld expect from a very lean fuel mixture. I went into the lambdawideband input in the options and i have selected the built in lambda because if i select the external wideband input from the ELD pin it won't read any air:fuel. Does any 1 know the correct settings/wiring/lambda voltage conversion figures to get a correct reading from tha o2 sensor? Any help is greatly appreciated.

Did you setup the voltage to lambda conversion table in the Hondata software for that input??
This is what it looks like in my S300, KPro is probably similar...
