Bad ecu
My F3 was constantly going into limp home mode. Took it into the dealership and they narrowed it down to a bad ecu. They told me that part is back ordered until January 23rd. Ugh!

Ours is a red, black and chrome 2017 F3 Limited. Bought new in 2/2019. The avatar is my first bike back in 1952, a Simplex Servi-Cycle. Photo taken at the Barber Museum.

roobus, how many miles has your F3 done?

I wonder if there was a problem with some of the early ECUs.

If I had a dime for every time an inexperienced tech decided the ECU was the culprit....
They VERY rarely fail. When they do, its very obvious when you connect BUDS as they either will not communicate at all or all kinds of odd things going on. The described failure (an intermittent code) does not sound like an ECU failure at all. Not impossible but not likely.

Yep, it's probably going to have the same problem when they put in the new one.

Do wonder....🤔
As the ECU processes all the information from all the sensors attatched to it....did they in fact check the sensors...? have any mods or work been done that could be interfearing, they seem to be the ones that fail most often. May be time for a second opinion....

I’m just going by what they told me. Said they’ve tested everything and have narrowed it down to the ecu. Said they took one off another spyder, put it on mine and it ran fine. I’ll lose my-sh*t if I get it back and it goes into limp home mode again.

This is a SAD fact of life - Dealers don't always tell the truth, and Tech's aren't always competent …. This is from Actual experience …. I'm not just repeating something I heard about …. good luck, hope it gets fixed ….. Mike
