Build the LS combination correctly, then give the ECU trustworthy information to work with.
A swap is easiest to diagnose when the mechanical install, wiring and ECU configuration are treated as separate systems with clear ownership.
FEF can review standalone ECU configuration, trigger/sync, sensor data, fuel/ignition setup and first-start calibration once the project is complete enough to test safely.
JP's Performance is heavily LS-focused and is known locally as ‘The LS Master.’ Project work can include Gen III / Gen IV LS swaps, DOD-delete builds, supporting installations and mechanical preparation, quoted by project. Selected standalone-install projects can be coordinated with FEF.
Standalone ECU commissioning for accepted engine swaps.
First-start support and timing/sync verification.
Dyno calibration after the swap is mechanically ready.
LS-focused engine swap/install support through JP's Performance, quoted by project.
Gen III / Gen IV LS and DOD-delete project support where applicable.
Clear handoff between mechanical and calibration scope.
