- o2 sensors oscillating 100 to 800. seems a bit wide. would be interested to see where these end up. this may mean its leaner than needed, the 100mv data.
- OL, was 862mv when you revved it. Thats leaner than I would want. shoot for 912mv and compare to wideband 12.4 or whatever your favorite number is for the 3% mix of ETOH.
ideas:
- log is around 38kpa idle. if inj are stock and pcm data stock, no changes recommended here.. If not, you can slightly dec fuel inj data around 38kpa and get an increased fueling. I always try and match stock fuel inj slopes or there about.
- MAF data. try to find out what stock engine airflow rates are reported for a stock 6L at idle. adj your maf to match that num in logs, then adj other params to get fueling needed.
- WOT is just a matter of the wideband. Make sure PE enrich is where you want it, then adjust MAF to get that AFR.
just a few ideas.
