Setting the RPM Counter
Once you have determined which position on your vehicle this reading is to be taken from (see manufacturer’s instructions) you need to tell the gauge the type of engine you are reading the signal from there are three settings to make. Incidentally I get the best results from the negative side of the coil.
Setting One 2 stroke or 4 stroke
Using the adjust button as before set for 2c (2 stroke engine) or 4c (4 stroke engine)
Setting Two The number of pistons.
Before we attempt this procedure,
Please see the examples below which might help you understand the set up procedure
Coil Connection this is just an example if in doubt try other settings
Engine has 6 pistons and 3 coils set the number of pistons to two
Engine has 4 pistons and 2 coils set the number of pistons to two
Engine has 4 pistons 4 coils set the number of pistons to one
Engine has 2 pistons 2 coils set the number of pistons to one
Engine has 2 pistons one coil set the number of pistons to two
Induction where you wrap around the HT lead do it about 20 times and cover it tightly with tape to hold it in place
In this instance you are only reading the pulses from one of the cylinders therefore on most occasions you will set it for one piston.
Setting Three The Hi Lo setting
If you connect to the negative side of the coil set it to LO
If you connect it to the positive side of the coil set it to HI
