Hi, do you have plans to divide fuel film to fast and slow portion, like in other ecu where is same fuel film system?

And i think can be nice also have ability for additional enrichment/delay for fast staged injection transition, i found it needed when secondary injectors are mounted very far(on other ecus) and here is nothing.

Thank you
