The low level issue. If you have an injection system installed, it must have a functioning low level warning device. If left to chance, at some point you will guess wrong! Whether it’s a light behind the dash, on top of the dash, a factory “Low Warning” etc., the location must be clearly visible.

The only exception to this rule is on professional race applications that require foam added to the fuel cell to prevent excessive sloshing. In these applications it is common for fuel, water, oil, and other liquids be inspected after every run.

Ok, we’re sure system has liquid. Now another “what if”.

Second:
System test. A “fail safe” injection kit MUST have test button readily available for diagnostics. our PAC controllers feature a low-pressure test of the system. It’s important to note that this is NOT a full pressure test that could potentially hydro-lock an engine.

Ok, we tried the test button and the air/fuel changed. Now what?

Third:
Diagnostics. A Progressive System: This feature allows the system to begin spraying early with very low pressure and substantially before detonation assistance is needed. Once spraying begins an LED light is illuminated, indicating system activation. As the signal (MAP/MAF/Boost) to the controller increases so does the drive to the pump. Once the system pressurizes, the LED color will change from red to green. This indicates the system now has developed pressure and that hoses, connections, and pump are in proper working order. The “rate of change” from red to green give a predictability of the system. Any noticeable changes to this “transitional time” will be an indication of a system issue.

Examples:
The filter clogs…the system will transition from red to green instantly.
Nozzle clogs. (oops, can’t happen…we have a filter.) Someone pours a bag of sand into the tank…system lights up red, can’t make pressure, no green condition.
Bottom line, a well-designed, basic setup provides a simple, easy-to-diagnose system that is RELIABLE.

Scot,

you obviously have a nice system, but there can still be failures, and a guy running through the gears at wot may not see the light changing, etc. Don't get the red to green instantly deal if the filter is plugged, seems like a red light is a better indicator of trouble. Now I have to watch how fast the led changes............I do know it's tough to watch lights/gauges when going wot with a 1000 hp street car. Unless your system would automatically cut boost and change the timing if there was a failure then you're still depending on the guy noticing the leds. I am not knocking it, as I said I use one on every build including my current twin turbo. Haven't tried yours, but have used 4-5 different ones and other than features they all seem to work well.

Also, you really should consider becoming a site sponsor.
