Pop and bang issue with the MT-09 – it happens too intermittently.

in FZ / MT 09

I’ve modified the ignition timing and adjusted the decel throttle settings, as well as the fuel amount during deceleration.

I also disabled the deceleration fuel cut option. From 3,000 RPM to redline, I set the ignition timing to -12° at 0% throttle.

I’ve tried doubling or even tripling the stock fuel amount during decel. The pops and bangs are strong when they happen, but they occur too intermittently—and sometimes not at all.

I’d like to make them happen more frequently, even if they’re less aggressive. What should I tweak to achieve that?

Thanks!

P.S No cat, full exhaust, Hi-flow airfilter installed

    Hello,

    So are you trying to intentionally create the pops and bangs or do you want to eliminate them?

    What is your ecu part number?

    hello how's your pop and bang mapping now?

    For Me I retard the timing as far as 2 percent on the throttle Position. Try not to retard more than 2 percent as this will affect rideability.
