The answer to this depends on the particular engine configuration and how your injectors are wired with respect to Bank 1 and Bank 2. Once the car is tuned and running well you can play around with these values (simultaneous versus alternating) as well as the number of squirts per cycle. They can make a difference in idle quality, tip in (off throttle) and low speed performance.

Common plenum and mild cams work well with either simultaneous injection. ITBs and bigger cams with more version often need alternating and more squirts to avoid fuel loss due to reversion and puddling of fuel when it comes back down to the intake valve at low speed.
Jamie - I can explain it to you. But I can not understand it for you.
