Speedo passion strange LED

[Big G]

In the cat I have a LPF with a 5.5 motor at the moment.

Both have performed perfectly for almost a year together now with the occasional swap to the 6.5 or 7.5 track dependant.

Last night at club I noticed after a run the green LED was flashing constantly. My dad running LPF+6.5 also has the same thing. The motor was temp gunned at 129 degrees in my dad's car. I wouldn't say mine was overheated at all. (20/81 with 23/33 gearing)

I changed my motor for the other 2 and the green light doesn't flash. back with the 5.5 and it flashes again. The car performs awesomely with the 5.5 in, but would just like to know why it's doing it. The manual says when the ESC is overheated the flash will be *_*_*_ not 100% if this is the same as mine, but now the ESC is cold and it still flashes, plus it doesn't do it with the other motors. I have also reset my speedo back to defaults and the led isn't lit until I give it some throttle and it starts flashing again. Red LED comes on during throttle and braking as normal and green LED lights at throttle end point.

Any ideas?
