88 PE SA correction for AFR

how can it correct an afr of 9.9 using a narrow O2?

I have a very unique programing need an I'm trying to find the best and easiest starting point. I worked on 8D for a long time... it seems to be VERY well supported and documented but... I don't really like ALL the extra timing tables and other stuff I won't use for my racing application.

So now I'm taking a close look at 88. Thanks for the help.

The 9.9 AFR is the commanded AFR, not the O2 sensor feed back value.

Set your PE values to be somewhere between 15% and 20% (and make sure the VE is right). Don't know how to do this in 88, though, never looked at it.
