HP Tuners / EFI Live WorkflowLS3 And L99 Cam Calibration Direction
LS3 and L99 cammed cars need calibration work matched to the real combination: camshaft specs, airflow model, MAP sensor, injectors, converter, headers, intake, fuel type, tire size, gear ratio, and transmission details. L99 builds also need the file matched to DOD / AFM delete and VVT delete status where applicable.
Startup, Idle, Speed Density, And Drivability
JR Jones Racing builds remote startup tunes and cam tune files for supported 6.2L LS cars using HP Tuners workflows. The goal is a clean first startup, stable idle, correct fueling and spark direction, and a file that can be revised from feedback and logs when needed.
