Need help with code 81, grip warmers not working.

I finished installing the new handwarmers yesterday. I fired the sled up and put them on high and within 5 minutes they started to get warm. I’m excited to see if they outperform the originals. My sled is a 2010 so it was supposed to have better handwarmers from the factory but they’ve sucked from new. Unfortunately I’m currently nursing a knee injury so I don’t know when I will be able to actually ride the sled to see how they perform.

The grips will not get hot at idle. The ECU will only let full power to the grips after 5k rpm. It also limits power to the grips when the brakes are applied.
Do yourself a solid and get Yamaheaters with boost. This is the best way to keep your hands warm. The system has a Nuclear setting that sends full power to the grips at all times.
Another mistake people do is wear too much glove. Too much glove does not let the heat from the grips to you hands.

Any chance you know the part number for that harness? I went to my dealer yesterday and the parts guy couldn't find it.

Found it in the FAQ section

I figured they wouldn’t get hot just sitting there idling. I was actually surprised that any heat came from them at all. In the past when my sled was idling my grips would still be ice cold so the fact that there was any warmth coming from them at all was an improvement.
Yamaheater with boost is next on my list. Anyone that I know who rides in Apex without a yamaheater installed gets the link sent to them from me.
Recently a friend purchased a 2006 Apex and told me he couldn’t believe how hot the handwarmers were. I told him there’s no doubt there is a yamaheater installed on that sled then. Sure enough when we looked it had one.
