    Injector timing?

    Setting up e.f.i on my 97 aprilia sr50 from carb. An wondering what is the injector timing the factory sr50 uses?
    Currently im running into a slight bog when i decelerate and try to give throttle. An i dont believe the settings of 1280.0 is working currently.

    Thanks for any advice

    I'm assuming not many people tune e.c.us here?

    You need to elaborate on your setup and what you are actually trying to get an answer to. You say you have a 97 SR50 that you are trying to set up with an aftermarket fuel injector? As far as the ECU on the Ditech/Factory bikes, nobody has been able to enter to see the the fuel maps and modify them yet, and I highly doubt we`ll see the day that some do, as those engines are no longer being manufactured.

    Well. That's a shame,just needed an idea of what the injector timing is on a stock engine to get a better idea of where i can set it up for my minarelli build. Its a midrace setup with an italkit alu, 28mm throttle body,c16,mhr over range.

    Im able to tune pretty much all the fuel cells along with controlling idle and wot timing. Just having a slight bog when i decelerate.

    Essentially injector timing is when the injector will open up to send fuel to the top end
