Just installed the race ECM and K&N...

[MPea3]

We've had the Drummer on Beth's cg for a few months now, and tonight I finally got around to installing the race ECM and K&N air filter. It fired right up and promptly stalled, firing up again with some difficulty and running very rough for the first few minutes as I ran around the neighborhood warming it up. With the throttle open it runs well, and I mean REALLY well, definitely feeling faster than before, and now it will idle, but the throttle response at low RPM is **** and it stumbles quite a bit when the throttle is initially applied, again at low RPM.

Is this normal until the bike's been ridden for a little while? Also, when we installed the Drummer we had some throttle response issues until we had the TPS reset, but nothing this bad. Will a TPS reset and some mileage cure this, or will Beth be happier with the standard ECM? As small and light as she is, this much jerkiness could be a safety issue around town for her.

TPS RESET as soon as you can.

TPS Reset and ride 5 mins between 3500 and 4500 rpm and that will re-learn the ECM

TPS RESET IS A MUST WITH THE RACE ECM INSTALL. MINE RAN TERRIBLE ON THE WAY TO THE DEALERSHIP, RAN LIKE A CHAMP THE WAY HOME.

just installed a drummer today on my xb12ss. i spoke with the tech team at legnth at the stealership and they swore the 08's did not need a ecm tuner or any changes to the air box. thoughts? the diffence with the exhaust was what i had hoped for. had to grip tight to hold on :)

Probably do a TPS reset and a good "learn-in" ride and you should be golden for awhile. The '08+ ECMs can handle an exhuast OR intake mod, but can't fully compensate for both.

It'll be rideable but the best thing for the engine in the long-term, is to have a remap.....and Xoptiinside.com is now back in business. The remap will be money well spent.
