stafford wroteIf there anything that can alter timing if required?
Simple answer, Yes! Is it simple? Depends?
You need an eprom burner. (About $50 on eBay)
A Windows operating system running TunerPro software (free d/l)
The .pdf file for your vehicle. (P8-P7/eprom specific.)
Spare eproms/eeproms to burn or erase.
An eprom puller so you dont bend the pins! (Optional)
Guzzidiag website has a bunch of the .xdf files. Download the apropriate one for your bike's computer. Load it in Tuner Pro. Remove your eprom. Read and save the eprom as a .bin file. Open said .bin in TunerPro. You should be able to click on the various tables, view and edit them. Save your changes (rename) Burn new chip. Install. VOila!
The newer bikes can be read/written to directly to the computer so you don't need the chip burner. Just the proper cables and the Guzzidiag reader/writer programs for your specific ICU. You still need the xdfs to open and edit the bin files and save your changes.
Good luck and tune at your own risk!
