I could go search, how about a link?
What does it take for inputs and does it know the fz is using waste spark?
EDIT:
FWIW: I have a hex dump from Winlos of the FZ6 ECU and there are three maps. 1 & 2, 3 & 4, and 5 & 6 gears.
Comparing this to its cousin the R6 shows it is by no means in jeopardy. If nothing else it will improve throttle response, engine smoothness, drivability, power output and fuel economy if limits are not exceeded which induce detonation.
Currently mine is statically advanced an additional 6.5°from the stock 5° by rotating the trigger wheel. Bike is very happy but does indeed want better grades of fuel and at idle it is too much advance. But its not doing any work at idle so I don't care.
Do an image search for R6 ignition maps and when you see how badly they neutered the FZ6R and FZ6 you will see there is a good deal of freedom if you pay the penalty of higher grades of fuel. What mods have you done to the bike if any?
I have a few sound clips loaded on soundcloud under fz6-rippedmp3. Give them a listen as its a cheap mod and it helps but I want more, hence poking the ECU and comparing the three bikes listed as well as FZ1 and R1... When I figure it out I'll post up but it's going to be springtime!
