I certainly can see why you would choose to not use it. But I have been experimenting with the pe/be thing and I think it is very helpful. There is plenty of times that I can be in pe and not be. I just simply don't have boost yet, but I have my pe on at 93kpa. so there is some time there before 105kpa I am enjoying the "leaner" scenario because the "richer" scenario isn't needed yet. And as you know, that could be over a sorta wide RPM spectrum. Just completely experimental for me, I have no idea if it is more powerful that way. But I am not defending me keeping the pe, I am defending the way I drive, I at 45% to 65% tps ALOT and border the boost line.
WOT, yeh...no pe.

I just set the PE to something reasonable and run up the BE values from there. As you add manifold pressure, you need a slightly richer mixture-to a point.
An advantage of BE is that you can richen/lean out a particular MAP line to suit your vehicle. The biggest advantage is that you can adjust your PE (BE) value to suit the manifold pressure.
If you are 1 bar + MAF you can only achieve the PE value which may not be optimal if you are not at full boost.
And the final benefit of a 2bar table is that you can go into the VE and richen or lean a particular area to suit the engines needs.
