I think I'm pretty close to getting OL MAF working. Just stuck trying to get my user selectable wideband source list to populate before I can test. Might just hard code it for testing and figure the list out later. I also added a field, Correction Factor, so you can tell it how much change you want applied when you apply to MAF table.

Look at the AFR Source code commented out in the MAF tab.

Yeah, I uncommented that and thought Paul had made it REALLY easy on me, but his code didn't ever build the source list, just built a panel to display it on. Realized that the first time I went outside hoping to test (with my fingers crossed). I need to find the code that adds params to the main logger tab.

Edit: Oooo, I was wrong, he did have that code in place. There were a couple commented lines I missed. I'll try it out here in a bit.

Kind of on topic I hope.

ID1000's claim to fame is their linear response. This got me thinking about the per cylinder injector compensation tables. Would this be a good place to correct for non-linearity of other injectors at low pulse widths?

Not a lot is known about the per cylinder adjustment tables, but based on Bill's description it looks like it just increases pulsewidth by the percentage defined in the table. If you're looking at injector flowrate as a logarithm I'd assume it would just move the entire curve up. The tables are really there to compensate for differences between the injectors or whatever other factors would cause you to want more or less fuel in a specific cylinder. So in my opinion, no, I don't think that would be the way to do it.

I think injector scaling, latency and MAF scaling are really it for adjusting for injector flowrates. Unless someone wants to hack in a 2d injector scaling table. ;)

You do need to rescale the per cylinder injector compensation tables if you change from stock injectors. These tables are pulse width driven and that gets smaller as injector flow increases. But to change the values of the table, that's a different story altogether.
