I've had my Roxor for about 2 weeks now. I've driven it 70 miles so I'm still in the breakin phase. I've noticed when driving that if I rev the engine higher than 2500 rpm's I hear a little pinging noise. I also notice a burning smell. Is this something that will go away after she's broken in?
The engine is rated at 3200 RPM'S, But torque is rated at 2200 RPM'S. Being that the engine is ECU controlled, it is possible that the "Pinging" is being caused by the ECU cutting out cylinders, or adjusting injection timing to compensate for driving conditions that are exceeding the programmed rpm parameters. Try gearing up or down 1 gear under the same driving conditions to see if the ping goes away. As far as the smell goes, as others stated, it IS normal. and will eventually go away. Same as "That new car smell". Hope this helps.
