I don't know who or why you would expect it to read double.
The tach in 4cyl mode is expecting 2 pulses per revolution. a moped only has one ignition pulse per revolution, therefore only reading half, not double.
Like i said, run it on 4cyl and double the reading. 16K tach if you have 12vdc to power it.
Ryan, i am interested in your 12v dc rig? is there a thread on it?
do you have a schematic?
