12598646 52 lb/hr Gen 4 to Gen 3 Injector Data

Injector calibration data for Gen 4 stock injectors, part number 12598646 (52 lb/hr), converted for Gen 3 P01/P59 PCMs using HP Tuners. The source workbook identifies LSA and LS9 applications and notes that the spray pattern is specific to the LSA/LS9 supercharger manifold. Verify that spray pattern and hardware fitment suit your manifold. Match the actual injector part number before use. Includes one Midgard Industries Excel (.xlsx) workbook with: - Injector flow rate vs. kPa vacuum - Minimum injector pulsewidth - Injector offset vs. battery voltage and kPa vacuum - Short pulse adder Flow-rate and offset sections include non-referenced (returnless) constant 58 PSI and manifold-referenced 58 PSI base configurations, as labeled in the workbook. Digital data file only. Physical injectors, HP Tuners software/licensing and a complete vehicle tune are not included. Verify PCM support, injector identity, fuel pressure and table units for your setup before applying the data.

Gen 3 P01/P59 PCMs with HP Tuners; Gen 4 stock injector 12598646. Excel or a compatible .xlsx viewer. Select the tables matching your fuel-pressure configuration. Confirm hardware fitment independently. Source notes a spray pattern specific to LSA/LS9 supercharger manifolds.
