A built-in light sensor dims the display automatically at night, and increases brightness in direct sunlight.

A ten segment bargraph display shows amount of retard, and thus gives an indication of the engine's tendency to knock at any particular time. The monitor is connected to the J&S SafeGuard with a 3.5 mm stereo cable supplied in the kit. The new SafeGuard units have an onboard LED that glows in proportion to the amount of knock retard. This will assist you in setup of the SafeGuard, but the bargraph gives much more information.

MSD Engine Knock Alert - signals you to engine knock with a series of lights and an audible beep. It has a sensitivity adjustment that lets you tune it to the knocking characteristics of your coach. This device installs easily with only 3 wires to be connected.

One of an engines worst enemies is detonation. It can occur at any time and if left uncontrolled, severe engine damage may result. Sometimes however, the pinging noise may be hard to hear or recognize due to well insulated interiors, engine compartments or excessive road noise. The MSD Engine Knock Alert listens to what's going on in the engine for you. When detonation occurs, it relays this information to you in two forms; a warning light and an audible beep. An extremely sensitive Knock Sensor is used to ''listen'' to the engine. This sensor is screwed into one of the engine block's drains or access holes (an adapter mount is also supplied). Once in place, the sensor relays excessive detonation noise to the Knock Alert. Since all engines make noise, some more than others, MSD added a sensitivity adjustment to the Alert. This adjustment allows you to ''tune'' the Alert to match your engine's characteristics. The Knock Alert is easy to install and features matching Weathertight connectors for firm connections. It will work on 4, 6 and 8-cylinder engines with 12 volt electrical systems and comes complete with the sensor, adapter and controller.

Ignition Timing Control - The dash mounted ignition timing control is the perfect complement to the knock sensor because it allows you to retard or advance the ignition timing without leaving your seat. Going over large hills is easy now. As you ascend the knock alert will indicate that the engine is knocking. You can simply reach over and retard the timing. After you reach the crest and descend the hill, you can advance your timing for more power and better fuel economy. MSD Timing Controls are designed so engines with locked out timing or crank triggers can take advantage of an ignition curve. The weights and springs inside your existing distributor are removed and the mechanical advance is locked out so the timing is controlled entirely by the MSD Timing Control. By controlling the ignition electronically, the timing curves can be set faster, more accurately, and with more adjustablility than mechanical advances. The Timing Controls provide reliable operation throughout the RPM range. MSD Adjustable Timing Control The MSD Adjustable Timing Control puts you in control of your ignition timing - from the drivers's seat! A dash mounted control knob allows you to adjust the ignition timing to compensate for changes in altitude, low octane gas, or heavy loads. For cars driven every day but raced occasionally on the weekends, this control is perfect. Increased fuel mileage and performance are just some of the benefits as the ignition timing can be advanced or retarded to prevent engine detonation. The control knob mounts to the dash board for easy and accurate timing adjustments up to 15°. The Control can be used on 4, 6 and 8-cylinder engines.
