I guessing it was DAF ecu ■■..If you still have the old one ,plug it back in …If DAVIE can talk to it they can read the parameters in the old unit ,then plug in the new one and programme them in ,then it is set up exactly as the old one …To just raise the revs shouldn’t be too difficult but again DAVIE required ….I do not know if Texa etc can programme or read parameters
