you can get the software and usb cable off the net then plug it into a lap top and upload the map to the box when the car is stationary
you really need a wide band lamda sensor to monitor the air fuel.. and some way of detecting detonation on the fly.
then its a case of run it round the block. alter the map a bit.. repeat till its running well in all gears and not running lean.. or so the theory goes..
