[Gmecm] Shift light

[William Lucke]

Robin,

Notice that the code Zaphod posted lays out N/V ratio windows for each 
gear. N/V is the ratio of engine RPM to vehicle speed.

IOW, without a VSS input, code that works like this will NEVER light the 
upshift light unless you program the upper bound for the N/V ratio 
window to infinity. I don't think that value fits into even a 16 bit 
location.

The upside is that you can program different RPM for different gears so 
you can REALLY have a shift light.
