First Retard Menu
Note that RunCurve is not listed, but there is an * on lower right of the monitor which means that
there is more to this menu. Push the ⇑ button to get to the next part of the menu, then click Next until
RunCurve flashes. Press Enter.
RunCurve Menu
Use the Next button to get to the RPM down to 800 rpm, the lowest programmable rpm. Then use
Next to maneuver to the RetDeg and use the arrows to set it to 20° of retard, then press Enter. This
goes to the Save menu and select Enter again.
Instead of moving through the entire menu Run Curve menu again, press Next until Copy is active.
Now by pressing Enter, you’ll notice that the rpm setting is saved and the Monitor moves to the next
rpm step (rpm). You only need to change the retard rate then press Copy again. Repeat this procedure
for the complete curve. At Deg 0, press NEXT, and ENTER to save the programmed retard curve.
Monitor Mode
In Scan mode the monitor will scroll through all of the settings (or the ones you choose) so you can
view each parameter when the engine is running.

Monitor This lets you choose what parameters you can view while the engine
is running, how long the view time lasts and confirm the Cam Sync
signal.
This confirms that the ignition is receiving a sync signal. It will display
either Sync or None.
This comes up on the Run and Launch Curve menus. It eases
programming each step by copying the value of the previous step,
with auto increment of Rpm.
Cylinder Count, for the number of cylinders of your engine.
The amount of timing that you want to pull out of the accompanying
cylinder. 0°-5.0° per cylinder in .1 Deg increments. You also need to
program which cylinder is receiving the retard rate, but note that this
is the cylinder sequence order on distributor, not cylinder number.
The amount of retard that occurs with each gear shift. A different
amount of retard can be activated for each gear from third to sixth.
This is the menu where you program the entire rpm curve in 100 rpm
increments of 0.1° from 0 to 25.0°. This is active in gear 1.
This menu lets you program the retard amount and the setting to ramp
it back to the LaunchCurve.
Magnetic Pickup Compensation. You can compensate for different
magnetic style pickups (crank trigger or distributor) from 0° - 3°.
Selects type of input trigger device connected for optimization of the
RevLimiter.
