Although it seems to operate correctly while the engine is running my speedometer (stock FF kit) does not drop to 0 when the engine is shut off. Is this normal? Also, any ideas on calibration of same? Thanks
Speedometer ought to read 0 when the car isn’t moving, whether the engine is on or not.
Do you mean the tachometer?
A lot of times, as they get older, they don’t go all the way back to zero. Not a worry, I’d say, unless you were really depending on its accuracy for racing.
