Hi, Lou.
Very interesting. But what exactly is exhaust "beat frequency"? Is that the audible pulsations in the exhaust note? Wouldn't that simply be a function of rpm (frequency that exhaust valves oven and close)? Or is there more to this?
Please elaborate. It sound interesting.
It does seeem, though, that it won't work for me because I no longer can get BEFORE data to compare to the AFTER vehicle that I now have -- I'm assuming that it can make comparisons, for degree of improvement.
Looking forward to hearing from you.
