On http://www.hondata.com/techtuning.html they mention tuning the a/f mixture by adjusting the injector multiplier. What is it? What does it do? Can it be tuned manually or do you have to tap into the ECU?

TIA

 

It is a calibration program within the Hondata program. It bases the result off the initial injector size, new injector size and new fuel pressure.
It is not something you can get your ECU to do without having it reprogramed...

It's the overall multiplier of the entire fuel map. Each value in the map is multiplied by it. So if you change your fuel injectors from the stock 240cc (multiplier is 1) to 450cc injectors, it will change your multiplier to .533 to compensate for the larger injectors. This is something that you set up in the ROM editor with the rest of the maps etc.
