The duration maps are to be changed if you want to inject more than indicated on the reference axis (from what i remember 60 mg/r in tdi 130cv)...the Start of injection map are to be tuned only for hard tuning, if you have high duration and conseguently high egt it helps to drop egt.. to achieve a soft tuning on tdi 130cv you can retain stock duration and soi, just request more fuel through other injection maps:)...38° of duration are more than 200cv on tdi 150cv.... |
