Red is actual car Black is from rf2 Is there something I can adjust in rf2 to add some noise to the engine so that I can better match log data? Idle is REALLY smooth. In general: so is the rest of the rpm log data. I found the sinusoidal pattern after the 10th? restart on this log data interesting, seems like the car was hunting/adjusting the idle higher when it anticipated a stall (It was still warming up).
