2010 m8 low octane/exhaust temp sensor fail codes?

[Braaap12]

I have a 2010 m8 with a speedwerx pipe/y-pipe, jaws can and a PC5 tuned by racinstation. Last ride I went on the sled started running like garbage and I got a low octane light( I had fresh 92octane fuel) I shut the sled off then fired it back up and it ran fine, a little while later I got a exhaust temp sensor fail code? Anyone had this issue?

just think you got a few gallons of bad gas at your last fill up...oh and check your tailight wires for a short...but seriously that last 92 gas just may have been just a tad bad..
