Paccar ESA chassis file

[Colter]

You wont need a file from another truck, if it needs an update prior to programing you'll need the SW file for your truck or if ESA is too old it wont connect fully to program.
Otherwise set the boost gauge to either virtual or multiplexed option. If it wont program cause of a vin error switch the vin to engine serial top left of the screen, confirm and program. you'll see the vin pop up when you do that, sometimes manual input is needed.
