That's it! I'm effing done with this ECU! Going to megasquirt!

Why is it that my fueling is so high on the lower KPA's? I know I must have made an adjustment to some kind of variable that did this but I do not remember what it was. It actually runs good this way but I know this is wrong and it wasn't always like this. I am posting todays .bin with the skewed map. notice it is really high on the left side lower KPA's.

Now I will post the .bin from xact dyno the day I dynoed almost a year ago. It ran perfect that day but if I use this bin today it is way too lean. What did I change that skewed my fuel maps so badly? I know my maps should look like this one from xact dyno.

You should be logging with a WB and a fuel pressure transducer.

How am I going to plug that in to tunerpro? Can I splice that into my ALDL somehow? I already know for sure the issue is in the tune and not a fuel supply issue. It's a fuel control issue.

I wonder what is happening with the BLM averages and O2 sensor data? See sample screen shots from TunerPro RT and Log File Analyzer. It would be very helpful to post a .xdl file for us.
