Sounds like you've got the "Holy Grail" ; forgive my ignorance but what is a "Woolwich re-flash" and how do you get one in Australia?
Look them up online.. you can buy their flashing kit, or give them a call (i just did) and they'll provide you with a list of tuners who use their tuning kit.
I'm in Melbourne and they gave me a list of 4 different shops around town.
i called one and they quoted me $900 to flash the ECU and dyno it. also told me that if you're going to mess around with disabling o2, you have to get the bike re-tuned..
the blokes in youtube make it seem a lot easier than that!!
Just spoke to 2 different tuners and it seems as if though when you flash the ECU, you need to re-tune the bike, so you can either purchase the kit, install, and get some dyno time, or take it to a tuner affiliated with Woolwich and get them to do the whole thing for you.
the second place have quoted me $800, but will take around 5 days, which sounds ridiculous.
