The numbers in the fuel blocks represent fuel in percentage. O means nothing is added or taken away from the stock map.

When the unit is plugged and connected electronically there is a green or purple floating dot on the screen, this dot represents where the engine is.

To change a number click on a block then hit the enter button on keyboard then type the number you want in the hit number again. You can highlight a number of blocks and hit the enter button and all blocks will change when you type a number in and hit the enter button again.

Go with whatever timing map DASA sends you.

Put O2 sensor in front pipe and do all your tuning then when done move it to rear and check it, if it needs more or less you can use the trim function to adjust it.

I was going to go into more detail but it is a lot of typing and lots more to it.

Kinda curious, did you call DASA and ask them how to do it?

Todd has a great map for the muzzy, I was just going to tell you that Todd has spent alot of time with the preliminary testing for the MSD I think I got one of the first ones Todd sold and my Teryx with the Muzzy and vforce john mod screamed and ran 68 mph on speedo, you can trust him on the MSD, also Steve at Dasa has done alot of mapping for the stock and the 840s.
