AEM water/meth injection failsafe / gauge

[mann]

Not sure if you guys that run meth noticed this, but AEM released it this fall. This is different then their old gauge. I just finished installing it and basically it will tell you not only if you have a blockage, but if there's a leak as well. Connects via USB, switchable gauge faces (before you chose the 500 or 1000cc versions), built in datalogger etc etc...


Switchable faces/scales:
Colors are custimizeable via software/usb cable


Sensor:


Installed. Not symmetrical because I'll be moving the wideband on the left later.



You set both upper and lower limits for the alarm. If the upper limit is exceeded you have a leak--if the lower is then it is a blockage. Since the sensor is right by the nozzle it is a true indication of flow.



The reason its a failsafe and not just a gauge is the fact that it has two outputs that could be used to either trigger a solenoid to bypass the boost controller and reduce boost, or connect to a piggyback/EMS to switch maps. Basically you don't have to worry about your meth/water failing and grenading your motor, since it will automatically retard timing or kill boost before damage occurs if wired in that way.

After playing with it for a while I was able to set it up so I had 150 cc of flow at low boost, 300 at high boost, and max at 400 in case I boost creep. Before I was spraying blindly basically 400 from 5 psi ON. So in that sense I gained a few HP from a more optimal flow progression.
