PSI HD Well Head Gas Calibration Update

PSI has launched an innovative “PSI Field Programmer” software designed to allow an ECM calibration update on products in OEM Factories or the field. This software tool eliminates the necessity for direct PSI intervention via remote access. This upgrade streamlines the calibration process, offering a more autonomous and efficient solution for calibration updates.

The launch of PSI’s field programmer software is strategically aligned with the introduction of new wellhead gas (WHG) calibrations for select PSI 21.9L engines. This synchronization ensures that OEMs or end users wishing to upgrade their engine control modules (ECM) with the latest WHG calibrations can do so seamlessly and efficiently, leveraging the convenience and flexibility of the new software solution.
