Engine light help
So I changed the exhaust in November and after +3.000km or so (a couple of weeks ago) the engine light showed up. The bike runs perfectly and everything works except the launch control system.
I have some friends that the engine light made the bike go in a “protection mode”. The can’t use the cruise control, change modes, quick shifter etc…
My question here is, does anyone know how to tweak the engine light without ecu tune or buying an emulator?

You can get a lambda sensor spacer, this fixes the sensor further away from the pick.
Look into it.
