AEM analog style methanol Failsafe gauge actively monitors the injection system's ENTIRE flow curve to compensate for failure under ANY condition, allowing you to use your water/meth system with complete peace of mind. This 52mm (2-1/16") gauge features seven built-in backlight colors and comes assembled with the black face and bezel with the extra silver bezel and white faceplates to easily adjust to your interior style.

More Info:
AEM’s Water/Methanol FAILSAFE Device is the most advanced water/methanol failsafe device on the market. It actively monitors the injection system’s ENTIRE flow curve to compensate for failure under ANY condition, allowing you to use your water/methanol system with complete peace of mind. If you have a water/methanol injection system or are considering one, you will not find a more advanced failsafe device on the market than the AEM Water/Methanol FAILSAFE Device.

• Can be used on virtually all water/methanol injection systems with either ¼” or 4mm OD tubing
• PC programmable with “Auto Set” feature that automatically creates baseline configuration
• Built-in warning lights inform user of an alarm trigger

Today’s water/methanol injection systems have proven themselves as a viable means for effectively reducing engine inlet air temperatures and suppressing harmful detonation. This allows enthusiasts to reliably increase boost and advance ignition timing without the need for racing fuel. Despite the proven effectiveness and reliability of water/methanol injection, there exists a potential for engine damage if the water/methanol tank runs dry, if the pump stops working or more commonly if flow volume decreases due to fuel contamination, a clogged nozzle or a leak in the system.

While failsafe devices for water/methanol are not new, competitors’ failsafe systems have limitations that do not allow them to completely protect your engine if the water/methanol injection system stops flowing. Most failsafe devices have settings for high and low range flow parameters, but only monitor flow at a single point. And, without actually calculating volume versus time to establish a flow rate, instead running the system at full blast and using the nozzle’s potential for flow as your established flow rate, it is impossible to know the actual flow of the water/methanol system. Short version: if you think you are flowing 500cc/min and are actually flowing 300cc/min, and you are relying on your failsafe to trigger an alarm at a single reference point using 500cc/min of flow as your reference, then you have created the potential for engine damage.

Other competitors’ failsafe systems use a flow meter to establish water/methanol flow and utilize an external adjustment to trigger an alarm if the system does not detect maximum flow, using a time-delay strategy to compensate for part throttle operation. The problem is, water/methanol flow is rarely zero or maximum flow, and with all of the potential flow rates one can experience, a time delay strategy is not completely failsafe.

• Actively monitors the entire water/methanol fuel injection curve to trigger an alarm event under any defined adverse condition!
