I have the JD Jetting tuner on my bike.  Is there a way to remove the smog device on the left side of the engine (the one with two air hoses and one wiring harness attached) without a "service engine" light showing up?

they make dongle plugs that you plug in to the harness and keep the engine light off.

Thanks for the reply.   Is this the device you're talking about?   It's on the left side of the engine.

Also, any chance you know who makes the plug-in dongle for this device?
