Mack metroliner with a Cummins 8.9L ISL conversion, previously fitted with a 8.3L isc with an auto box. Had to redo the ecu parameters and create an ecm code to match the truck specs, being an imported engine there is no data on these engines, a lot of hours and frustration but managed to create a program to suit the manual box and the Mack multiplex system that drives the ecu, with that being said I had two more ecuโs to create files for with that Same Cummins ISL engine going into kenworths t350โs a lot simpler system ๐๐ผ itโs been a solid few weeks.
