? about calibrating viper gauge

[redsnake3]

does anyone know how many pulses the gauge takes? what about memory, is there a way to change the memory on the gauge?

Thanks Redsnake3

are you trying to get the speedo to read accurately? if thats the case, just remove 1 tooth from the pickup gear on the driveshaft. if your talking about the tach, i have no clue! lol!
