Please read the whole thread from the beginning. I clearly explain, in the very first post, that road noise is governed more by the road surface than by the car's speed or the revs of its engine. For me, at least, it's much more desirable to have road-noise-based compensation than speed- or tach-based compensation.


Busted. I replied within reading through the entire thread. Sorry. Still think that the tacho controlled volume control would do in must situations. Isn't there a analog input port on the pcats tuner btw ?
