It's because VE and MAF counts should go up with higher TPS and RPM -- but, the load tables must also activate different cels in the VVEL maps, which is where all the actual throttling takes place. Finally, there are target AF maps that also correpsond to those load values.

Basically, no matter how you scale the tables, actual physical VE will not reach maximum levels unless RPM is approaching redline and throttle (as controlled by VVEL) is wide open.

If the values in the table don't corerespond well to physical reality you will most likely get herky jerky engine responsiveness as it tries to maintain whatever the target AF ratio is for the corresponding load cell.

Can you adjust timing or fuel on tip-in? That's a great way to improve throttle response!

Also -- do the values in the map correspond to injector duty cycle? I'm guessing that they do, although exactly what 3800 means isn't clear to me... uprev doesn't use intuitive cell values for a lot of the maps...
