MegaTune should work out your req-fuel for you,

Injector opening time - leave as default
Battery voltage correction - leave as default

PWM current limit(%) -
PWM Time threshold(ms)- These depend if you`re running low impedance injectors, if you`re running the TT injectors and resistor pack the current limit would be 100% and time threshold 25.5ms.

You want baro correction on.

The rest are engine specific, I run 2 injections per cycle on my other car and it`s smooth enough, you need to do some good reading up because f you don`t know what to put in here you`ll be lost when it comes to setting the rest up.
