Bonneville America Forums Forums Technical Forums Performance Mods had the airbox removed...

The "wires that go the pipes in the front" are the oxy sensors in the headers and, although they are necessary for the AI to operate they are not removed as part of the AI elimination. You can remove them AFTER you have disabled them using TuneECU and then you will need to plug the bung holes with M12 1.25 pitch thread bolts and the wires can be disconnected under the tank. If you turn the oxy sensors off and leave them installed you will ruin the sensors (I learned this info too late).

Just to clarify - the oxy sensors have no function in the normal engine operation and when the AI hardware is removed the oxy sensors still send exhaust gas info to the computer and the computer still tries to adjust the exhaust gas but the removal of the AI plumbing means that nothing happens (except pointless clicking from the AI pump under the tank). Remember, the AI only ever operates on closed throttle, so the oxy sensors on our bikes have no useful purpose other than the exhaust emission control on closed throttle. It would have been great if Triumph had used them as part of the engines tune self-diagnosis and self-rectifying map modification.
