325i intake valve map:

330i intake valve map:

low load is basically the same but part load and full load are completely different. at first I thought the 325i was more aggressive but now that I see it, it basically peaks out at about 80% load. I guess partly to make up for the lack of the 3 stage manifold?

this is really just scratching the surface though. this will take months of effort to figure out, I don't even know what the effects of this map and many others truly are.

I have to stop for today but I'll post more as I find it.

oh yeah, the left axis is rf (relative filling) and the top axis is of course RPM. the units are in mm.
