Wide Band Tuning ?

[ikle]

When doing a third gear pull my WB O2 reading was 11.6-11.7 with no knock. I want to get the WB O2's down to 11.3-11.4. What % of WOT fuel is needed to accomplish this ? Is there a rule of thumb when adding fuel ? Thanks, Kyle.

Rule of thumb, if wideband reading are 11:7 adding 10% more fuel, wideband should read closer to 10:7.

In your case, try adding 4% at WOT to get reading from 11:7 to 11:3

This method worked for me with Eric's chip.

I read that for a non Alky car you want to be in the 11.2-11.4 range.

I read that for a non Alky car you want to be in the 11.2-11.4 range.

I thought that these numbers are more of a range or safe starting points, since every car is different and some will work at one number and others will not. anyway thanks for the info.
