Epsilon 120 grab

Hi all, l recently had an ECU replaced over the weekend ( £930 ouch! ) and set to original spec. Went out to work today and when l put the pto on for the grab its running very slowly… At 800 rpm!
Any advice on how to pick the revs up to get some power back…?

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
