Had a code 21 start flashing on the way up the trail the other day. I shut the sled off and the code never came up again. What does this code mean. 09 m8 snopro with a twisted turbo and boondocker 3 degree timing key
Code 21 is your detonation sensor going off. Code 23 means you've pushed it too hard and really made the sled mad. You need to add fuel or back off the boost.
