It is a dual software. $ 0000 to $ 7FFF and $ 8000 to $ 10000

address of the map you're interested?

00BC This is the main fuel map afaik, for the z factor use 0.390625, z is VE, the x and y is rpm and map, use steps of 400 for rpm, this seems to work, 11 x 16
016F This is the fuel map for low rpm, only goes to 2400rpm, works out same as above for factor and axis, 11 x
032C, 03A8, These are afr maps, 9 x 13, the factor is 0.1 with precision 1, thats all Ive figured sof far.
0884, 0937, 09EA are your spark maps, the factor for z 0.351563 and x and y are rpm and map, z is dgrees btdc.
Add 8000
