Hondata

For some reason my air fuel ratio stays at 9.9:1 and doesn't change with the o2 sensor voltage. Also when I go to error codes it will not show the code. The check engine light is on and iI know what the code is because Hondalogger sees it but the my palm doesn't. Why is that?

What is the error code?

The code is for the knock sensor. I'm using a p28 and the person who burned the rom forgot to turn off the knock sensor. That's why the light is on in the first place. Hondalogger shows it but palmlogger doesn't.
