Help,

was out for a good fast spin last night , the engine warning light came on after about 20 miles. Stopped the bike and after i cooled down, checked oil and coolant etc.
Did install a USB 3 power commander a few weeks ago but tried taking it out of the wiring and still the damned warning light is on all the time.
Its an xt660x 2007/8 model.

any suggestions?
