I have the same issue! 2002 efi 2litre engine says 5 degrees but this is "Base Timing Mode" I adjusted mine to this not realising that the ECU sets the timing unless you set to base timing mode. Ops dosent run well if you set it to 5 degrees without it being in base timing mode I discovered!!!! My advise for EFI engine leave it alone until you find out how to force Base Timing Mode. I have yet to come accross this info so mine is set Roughly where it was before I Fiddled with it !!!! I am also open to ideas on how to do it Properly.
