I'll start at the beginning...
2016 Icon with Termi race slip-on with Up Map key installed, no baffles.. engine light had never been on in 1500 miles.
I didn't like the surging at low rpm/speed so I installed a pair of o2 sensor eliminators (eBay ones from Greece), physically removed the o2 sensors and used plugs to cap the holes in the exhaust pipes.
Took it for a ride, surging had gone BUT when accelerating hard ie. throttle opened up lots, if I then fully closed the throttle for 2 or 3 seconds, the engine management light would come on.
It would stay on for around 2 seconds.
I presumed that even though the o2 sensor eliminators gave a constant voltage value for the ecu, the ecu wasn't entirely happy and so produced the engine management light. At this point I must point out I still had the oem air filter in.
I felt that I wanted the fuelling to be spot on so I had my ecu flashed by Rexxer.
I told them I had the Termi race slip-on, up map key installed, no baffles, o2 sensors disconnected and physically removed and that I wanted the o2 sensors switched off in the ecu. I also installed an pipercross air filter.
Put the newly flashed ecu back into the bike, started it up, let it idle for 5 min (didn't touch the throttle) and then rode it gently for 10 miles after which I rode it harder for another 10 miles.
When giving lots of throttle and then closing the throttle fully shut (same way as before), yet again the engine management light comes on in the exact same way as before!
I know I need to get it on a diagnostic machine to see what is going on and for it to hopefully tell me an error code.
It's been suggested that a sensor is playing up and originally with the o2 sensors connected and in use, it was masking the fault.
Has anyone experienced anything similar or have any ideas?
Many thanks.
