aluable, saving both time and parts, if and when you make more changes.

1. With the unit powered off press and hold

down both the SAVE and RPM buttons.

2. While holding both buttons down, apply power to the Timing Computer.

It will display a number that represents the number of cylinders in an
engine (the factory default is 8).

3. Use the

and

keys to select the number of cylinders for your engine.

4. When finished, press SAVE. This stores this new information and puts

the module back into Control Mode operation.

If you do not make this selection your

Timing Computer uses the factory default.

Make this selection only once per installation.
