Olfa afr
I know someone else besides me has had this problem, but I can't seem to get any clear answers on this. Here's the situation;
I have placed all my OLFA tables to 1.00 above 158 deg, but for some reason at idle I am still seeing 12.2 to 13.1 commanded AFR. I've checked my tune several times, but there must be something I'm missing. What else could be left? PE enable is stock except I moved the enable rpm down to 4500. I am in OLSD 2bar by the way, with the maf disabled.
Any help would be appreciated.

Here give this a try.... Your PE enable from 1200 and down was 0% throttle. Down in that area with it being richer than your OLFA, it's value is used. When you come out of the rev, you are above 1200 and under 64% TPS, so it moves back to referencing the OLFA which is 1.0. That is the explanation for the behavior in the log.

You have to log it here for it to work in there and right now the graph is for ETC%. Change both to Throttle Position % and it'll work fine.
If your wideband is accurate at all I'm surprised you even made it home, lol. It's a touch on the lean side. 19:1 should be more like 12:1.
