ECU Load/Injector Calculation

[JoseCabra]

Hi,

I finished the instalation of the HFS-3 on my 2008 STi and was going to start tuning it.
I started to modify the AFR tables to lean out the fuel in the areas that the system would be spraying but it was mostly and educated guess.
I would like to know if anybody know how to calculate injected fuel from the load or other parameters. Or how to relate injector duty% to load. Or if you had any tips on leaning the AFR tables.

Thanks.

(Thanks Richard for your rreply to the wiring question; everything installed properly.)
