yes you can,
You need 3x things,
1x Wideband sensor (LC1) $250
1X Tactrix Cable (Google limitless for nz supplier) $237
1x Laptop with 2x spare usb ports
then visit romraider.com pretty much your self tuning bible. If still not keen to tune or mess with the tables (Warning you could most likely blow your motor if playing with things)
You could pay someone to tune it for a easy $250usd, and they can do it over email, (etune)
All up, about the same price as finding a dyno tuner locally that can tune open source, and not ecutek.
