    Can you please tell us what truck and engine model you are working on.

    My first guess would be the unit is locked from engine changes for greenhouse gas emissions.

    dd13 cascadia. Nothing wrong with emissions. Truck uses a fuel catalyst made by pittsburgh power. Rarely does a regen lately. I was attempting to activate the engine fan switch and also how to install a water pump that is not variable speed. Older water pump that runs at high speed, but to do so i was told to deactivate the variable speed....nothing on the parameters section and then I noticed that section and decided to ask. do you know what is for? If you tell me that i can turn the turbo into an in da house flame thrower to do a 60 second regen I would also like to ask you if you have the vedocs key so I can turn the turbo up. thanks.
