I’m doing a couple upgrades, intake/full exhaust. What are the pros and cons of the ECU flash? I ride MX but don’t race just want my bike to run correct as to not blow the engine, can a flash tune it without a dyno? Any info will help.

You can flash tune it, but there are a few downsides. Without putting it on a dyno it is really only a "guess" as to the correct settings for your engine. Every engine is different and will require different air-to-fuel ratio. It also has the downside that if you make changes, you can't adjust the ECU without sending it in for another flash.

So can any power sports bike shop/ Yamaha dealer flash it or is there only special places that do it?
