Sort of. You can adjust injector scaling to correct for fueling errors where the entire range of MAFv's is off by the same correction (in other words, if your error is a straight horizontal line injector scaling will move it up and down). If your error is a straight line, but diagonal, injector latency will allow you to adjust the angle to make it a horizontal line. MAF scaling will allow you to fix both of the above PLUS make an error line that isn't straight (peaks, valleys, etc) into a straight line.
If you're sure your injector scaling is already correct, just use MAF scaling to smooth out the peaks and valleys in your error line to get everything to settle in to zero.
