    Think youll find the dyno guy will add a bit of fuel low down to eliminate that pop....smooth out the air/fuel ratio and she will be g.

    Thanks for the heads up
    I'm going to give your tune a go. After a good long ride the bike did misbehave

    What you can also try is when doing the ISCV reset - lift the bottom and top values equally above spec. by .02-.04V what this does is remove some of the throttle movement lag that the ECU is registering and more closely aligns throttle movement with ECU mapping - it seems to help - I validated this lag (on ISCV std spec settings) with a wideband O2 sensor and had maybe 1%-1.5% throttle movement whilst the ECU was registering 0%,. Balancing the throttles is really critical the more time spent getting the throttles balanced equally will provide more optimal running at 0% and very low throttle positions.

    Removing Decel popping can be a trial and error thing, there are options in Tune ECU add or subtract fuel (and estimated or known hPa in the L Table) at 0% closed throttle in the 1200 up to around 4000 RPM range in your ecu mapping on all cylinders. Some exhausts respond better than others to suggested ECU decal pop adjustments in mapping, while a more open / short exhaust would appear to be more difficult and almost impossible to remove all the decal popping totally.

    I assume you have the O2 sensor turned off or removed, else you will have issues.
