    Question about injector duty cycle.

    Heavily Mod e85 build. Got decka 60lb injectors with walbro255. At what duty cycle and p.w will you start to hit the limit? I was seeing 88 ,% and 19.1ms at the top of my 1/2 upshift shifting at 6500

    Most would say somewhere between 80-90% typically means its going static iirc
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Thank you for the reply bill. I hit 80ish within the last 300rpm before my shift point. With that said are they still with the rule to size up given the short amount of time in the rpm amount. In your opinion
