A few times this has happened to be my 4iiii PM has connected instantly to my 130+ but refused to read power until I turn 180deg to home a minute later it then shows Watt's for a bit until I free wheel and turn and then it does the same again. After a few spins round the block repeating this no reading/ reading process I go home and swap to my 1030 and it reads fine. The 130+ was working fine with the 4iiii two days ago and I suspect it will again. Has anybody any idea what is going on ? as I prefer the 130+ for training and racing.
