WATER/METHANOL FAILSAFE CONFIGURATION
The following is a basic guideline strategy for configuring the Water/Methanol Failsafe for the first time. The ideal time to
configure the Water/Methanol Failsafe is while the vehicle is being dyno tuned for water/methanol injection. Ensure your
injection system is fully functional with no leaks or clogs or other issues before starting to configure the
Water/Methanol Failsafe!
1. In the Water/Methanol Failsafe Configuration tab, click on Clear Graph and Reset Limits to zero out all settings.
2. Complete a series of long sweeping high load 3
rd and 4 th gear pulls going from zero to full injection each time to
populate the graph with flow data. Avoid making quick hard pulls as this may skew the flow data points. Repeat this
procedure until a baseline flow curve is established. Alternatively, if using the AEM Water/Methanol Injection System,
simply press and hold the test button on the progressive controller a number of times while the injection nozzle is
removed from the intake and pointed into a container.
NOTE: You may notice that a few random flow data points are plotted well outside of the normal flow curve when the
system goes from being commanded full on to full off very quickly. This occurs when the signal driving the pump is shut
off and returns to 0% injection very quickly while there is still a slight amount of measureable flow. The electrical signal
driving the pump can drop back to zero faster than the physical movement of the fluid flowing can be stopped. This is
normal behavior which should not create a false trigger and can be ignored in virtually all cases.
