hi guys
i need some input from you guys please.
when changing duration and soi
do you guys only change the SOI or duration aswell. i have heard that guys do 38 deg durations on polo tdi 130pd. and iv'e also heard
not to go to more than 30 btdc is this correct. can someone help me understand please?
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....
