Yep, but it can only interpolate the data it has in the map, the VEs. If that data is all over the place, as the graph I posted illustrates, the interpolation will be all over the place, and incorrect. Note that with a closed loop ECM, this is not a problem as the VE New values provided by the ECM are already interpolated. The map you generate is made from those VE New values. However, we're talking specifically about the Twin Scan here. We're not using the ECM's interpolated VE New values (on an open loop bike, there are none!). We are generating the VE New values ourselves from the AFR data we are logging. Essentially, what I'm doing then in my algorithm is emulating the behavior of a Delphi closed loop ECM.
