I have a USDM K20A2 setup in a 93 EG all stock. Attached is the parametersin .pdf format. I changed the extension to .doc so that I can attach it to this thread. Once downloaded please change extension to .pdf.
I have my parameters setup in K-Manager and have a few questions that you guys can help me with.
1. Under the VTEC Options, does the VTEC oil pressure switch enabled box be checked? I read under the help options that with the JDM K20A type-r motor this option should be disabled.
2. Closed Loop, Is it ok to run close loop regardless of climate change? If you look at the the datalog sheet 14 my AF is 28.76:1 at 899 rpm idle. When I switch to closed loop it jumps to 38:1. Is this normal AF mixture or is there something wrong with my primary O2 sensor? Where should the AF be at closed or open loop? What would you recommend open or closed loop for a daily driven car.
3. Idle, Where should my idle speed be set at? Is it ok at 900 RPM? Where should the idle valve duty cycle adjustment be at?
My main concern is the primary O2 sensor. I don't know if 28:1 AF is correct? What are normal AF at idle?
Any answers or recommendations are welcomed.
