GEN 2 Hayabusa Injector Balance map ???

Re: GEN 2 Hayabusa Injector Balance map ???

Injector balance does affect fuel supply,lets say you choose to spray all the fuel at WOT from the upper injectors,then you only have the ability to spray 270cc/min at 100% injector duty cycle. If you set the injectors to 50/50 then you can either spray 2x270cc/min at 100% duty cycle or 270cc at 50% duty cycle for both injectors. So injector proportioning will affect total fuel supply if you try to max out your injectors. Now in theory,changing them to 50/50 it shouldn't affect the rest of the map,but I haven't tried that on a NA bike so I can't tell for sure.

Re: GEN 2 Hayabusa Injector Balance map ???

I have a 2011 Suzuki hayabusa. I'm planning to run a 30hp shot of dry NOS. I read online to set my injector balance to 50/50. I do not know what that means. What is the Injector Balance Map used for? How do I tune this map? How do I set my injectors to 50/50? Thanks Mark R. Hello. Perhaps a bit late in the day to submit a post, but thought I'd drop a comment. Injector balance maps don't increase or decrease over all fuel supply, these maps simply determine the split of fuel between the primary and secondary injectors...eg on the maps where it states 100 this means that the primary injectors supply 100% of fuel against the corresponding fuel maps...where it states 20, this means that the primary injectors are supplying 20% of fuel and secondary injectors are supplying 80%. Fuel spray is more turbulent the further up the intake and provides better power at higher rpm. Fuel spray (or atomisation) provides better emissions lower down the intake (which is manufacturers do this to pass emissions requirements). For all the other values in the map (excluding the 100); if you subtract this number from 100 then that value will be what the secondary injectors supply, the total value is always 100% by both primary and secondary injectors. The amount of fuel supplied will be determined by iap/tps and these are the maps that you must tune in terms of fuel delivery. Obviously, exactly where and how you supply fuel will be governed by how much and whereabouts you supply NOS. Don't forget your ignition! It'll wreck an engine if you don't set your ignition properly. Injector maps really compliment stp to an extent. Hope it goes ok Seems like it would be easy to screw up these maps. For example if it is already 70% in lower injector and 30% in upper and you change the lower to 50% and forget to change the upper map # wont you be getting a 50/30 split? It seems like if Justin could make the 2 maps always equal 100% that would work better so if you take away say 20% in the lower injector map it would auto add 20% to upper injector map, but it doesn't, you have to type in the changes in both maps, hence were mistakes could happen if you don't make the correct entries??? Then really all you would need is a lower injector map if the upper injector map auto populated to always maintain 100%.

Thanks for the info.

Re: GEN 2 Hayabusa Injector Balance map ???

My understanding the injector balance map controls how the ecu transfers from the lower to the upper injectors as the rpm and throttle increases. If you want 50/50 enter a value of 50 in the table where you want both upper and lower injectors to share the load equally

Can anyone help me out here please?
