Hey everyone, my bike is a 2011 yamaha R1. i have a code 15 that comes up everytime i push my bike hard or when it gets hot. The previous owner told me that it needs a tune because it has graves exhaust with a muffler delete system. So the power mostly cut after going over 150mph or when pushing the bike hard constantly. If anybody has any advise for me I would appreciate that.

Check your tps in diagnostic mode. Insure the values are inside the range.

The manual is actually really good for these machines and the on board diagnostics are pretty solid.

Maybe the values should be different since i have an after market exhaust system? Or no matter what these values have to be the same ?

That's a good question. The answer is outside my scope of knowledge. Perhaps ask the firm that put together your tune?
