Some of the posts here have indicated that when running full-throttle, the LH system doesn't determine fuel requirements via the mass airflow sensor. It seems that people believe the LH2.2 uses RPM only during WOT to determine fuel needs.

Is it correct that the mass-airflow sensor is not used to determine fuel needs under WOT? How is it known that the MAF isn't used under WOT? The answer to this question will determine how I'll address fueling for more hp.

On other mass-air systems, such as the Ford EEC-IV, the MAF is used for ALL conditions. I can understand that the EFI system is run open-loop under WOT, but I'd think the MAF would always be the primary device to determine fueling.

Thanks in advance,
Keith.
