man mine is flashing EFI....... I took it in, and the error code doesn't save so who knows what it was......... I have read it is a possiblility the fan was on when i turned the key off........... I also am re-routing the exhuast breather for the belt to the front, wet belts annoy me big time......... Also I put a clutch kit in my wheeler, and am rather let down........ it really didn't change much in my opinion........... I got took i guess......... it is the speedwerx kit with black spring and some heavier weights????????
