Q1: Is the data logging just slow or weird on the 8051 PCM.

I've got a log here , rpm's stable within 30 revs. map increases from 62 to 86 in 6 logs.
The AFR Target moves around.
OK I can understand interpolated data .
open loop AFR target at 85 map is 13.0:1
90 map is 13.0:1

so why does the target at 86 map expect 13.1 ??
.... still wading through logs.


Q2:
What AFR would you target for low map / decel and why?
Stock is 14.3 on the Open loop AFR Target. I'm currently at 14.7
DFCO is currently switched off.


TIA
Mitch
