02 error bias value

Also, do not forget about the O2 error bias value at: 0x2F7. This
value can be used to decrease the AFR at idle. Again, for a rumpity
engine, it can calm down the idle.
Which way to move it to decrease A/F at idle?

thanks...

Re: 02 error bias value

Increasing the bias value will raise the O2 feedback target voltage level. That will cause a decrease in the resultant AFR. Note that this term in this context only applies to the '7747 ECM.
