Math and pumping losses
I am not certain that I am understanding correctly, but here goes. I was thinking that, if you used to formula to calculate(for a given combined gear ratio) what the steady state speed would be(minimal pumping losses or none if locked up), then compared that to the speed the scangauge showed from the VSS, could you not see, via the difference, the magnitude of the pumping losses? I was thinking of making an xgauge and using the math part(with constants representing the particular gear I was in, which would necessitate having a different xgauge for each gear). I have read the manual, but it doesn't go into the math much, and the xgauge coding manual leaves some stuff unexplained. Can the constants be non-integers, like .703, etc, and how would you do that? It says it is a 2 byte number, which would be 16 bits, so it must be a hexadecimal number, since it is 4 digits long. I seem to remember, though, that the first digit represents signage. Any help would be appreciated.
