The HP Tuners L5P ECM upgrade service for GM E41/L5P platforms upgrades your original ECM while retaining the vehicle's hardware; the original ECM is required for the service. This offering targets control module reprogramming rather than replacement. The service notes that it does not use a "replace ECM" function and does not require crank relearn or IMMO relearn, simplifying the upgrade process while keeping the existing module in place.
