EFI Tuner – RJWC – ZForce 800 Trail & EX

RJWC always recommend that you use a Fuel Tuner (EFI-tuner) combined with any aftermarket exhaust systems. This is to prevent the engine to run lean which can damage your engine. To ensure correct air to fuel mixture make sure you follow the Fuel Tuner manufacturer’s recommended settings.

An option would be a full EFI Tune with reflashing or similar. Problems with the exhaust due to the engine not running correctly are not a valid warranty claim.

If your machine differs from the base model you may need to add another tune, turndown pipe, etc, to make things fit and work correctly.

Engine damage caused by improper exhaust and fuel tuner combinations may void factory warranty.
