fuel trim rate of change

[touge tom]

Hi guys. Im experiencing some wild a/f ratio swing from rich to lean. I was told in a previous post I put up. I should check the rate of change. Could someone please explain what this section does and ckuld it fix the wild a/f ratio swing I have when @ cruising speeds?

Have you read the info in the help file at: http://www.hondata.com/help/smanager/cl ... losed+loop

I've read it but I doesn't explain what actuall changes. Is it the a/f swing when in between changing gears?

Say if I reduced the rate of change %'s would rapid changes in throttle position equate to a smoother/less a/f ratio swing.

This has nothing to do with throttle position. It has to do with the short term fuel trim values.

i'll re word what i meant.

Say if I reduced the rate of change %'s would rapid changes in engine load /vacuum equate to a smoother/less a/f ratio swing.

It is something you will have to try, what works well for one setup may not work well with another.

Thanks mate. I'll keep on it and keep at! If I get time off from work.
