The SCT/EFI Live/HP Tuners compatible data files are generated from dynamic characterization of the injectors in the same manner as the original OEM injector data. These are not stock values massaged by "Billy Bob the Backyard Tuner" The result is a better quality tune with less effort invested in the tuning process.
In addition to being fully characterized, the low flow control and tight flow matching across the pulsewidth range guarantees OEM quality idle and drivability.For a detailed description of the characterization process and the mathematics used by the PCM to process the data, follow this link.
