Yea I know it didn't 'change' maps per say, but meant did it quickly switch off the nitrous options.
I haven't tried getting AEM to control my boost yet. I have a profec b spec II solenoid (same as Apexi), read it runs at 30Hz, but only close option for that is 31Hz, is that safe? Need to read up on it more.

Everyone just so you are aware the SMC kit spray light will not turn on if the pump can not make >40psi of pressure. I have tested this myself and you should test it too if you need to reassure yourself.
Just simply drain your tank and refill with just a bit of water, unhook the line and jet from the car and place the line with jet installed inside bucket so alky/water doesn't get out side of it on the car at all. I threw a towel in the bucket to keep the mist down. After you do this hold the test button down you will see the spray light shut off once the pump looses its prime and is not make pressure in the lines.
It will do this becuase the switch ontop of the pump is a pressure switch set to kick on/off at >40psi. When the switch kicks off the wire has almost no voltage, when the switch is on and the pump is making pressure the wire has 4.5volts to power the LED in the controler and to switch the AEM Map.

I think the Maximum RPM is can be set by these
NOS Overrev Off
Units: RPM
Desciption: Nitrous will be activated only when the engine speed is below this value. This is an over-rev type function that should disable the nitrous under unsafe engine conditions or when on the rev limiter.
NOS Overrev On
Units: RPM
Desciption: Hysteresis condition for nitrous overrev condition. Must be set lower than NOS Overrev Off option.
I think NOS on above load
NOS Off Above Load
Units: Engine Load
Desciption: Above this engine load the EMS will deactivate the nitrous control. This can be used to spool a turbocharger, which will turn OFF the nitrous once the desired boost has been reached, or as a safety measure to prevent the nitrous from being active in an overboost situation. When the engine reaches this load point, the EMS will cut the active signal to the nitrous relay, and disable any trims that have been set. Set this to the maximum allowable pressure to be active.
NOS Reinstate Load
Units: Engine Load
Desciption: Hysteresis condition for nitrous load conditions. Must be set higher than NOS Off Below Load option and lower than the NOS Off Above Load condition.
NOS Off Below Load
Units: Engine Load
Desciption: The nitrous control will be OFF when below this engine load. Note: The nitrous will not necessarily be ON when above this engine load.

NOS Off Above Load 35.12

NOS Off Below Load -14.69
NOS Overrev Off 11000
NOS Overrev On 9000
NOS Minimum RPM 0
NOS Maximum VSS 255
NOS Minimum VSS 0
NOS On Above TPS .39%
NOS Off Below TPS 0.00%
This should work for you but you can still change the turn on points as wished just be sure to follow the rules you quoted above. Hopefully this helps get you lined out.

"NOS On Above TPS .39%" That differs from the original directions? Did you have to change that as well?

I was just out driving yesterday with a new wastegate spring installed, and the power seemed a bit "flat" in the upper RPM's.... so I took a look at the data logs and find that my boost as read on the AEM EMS was 27 psi, and my timing was flatlining! A/F ratio was a bit lean (not excessively so, just a bit) Came home and checked the alchy kit with the test switch.... it used to give a spray light almost imediatly after pushing the button, and stall out the car at idle. Now, after holding the button for a few seconds the engine starts to run rough, and after a couple more seconds the spray light finally comes on. I am not sure if the pump crapped out, or the lines between the pump and pressure sensor are plugged, but the SMC hook into the AEM produced a very safe outcome (zero knock on the log) it what could have been a really bad situation without the safety feature setup.

This is an interesting thread. One reason I am replying is to bump it. Another reason is to ask if anyone else has tried this with a kit other than the SMC and what were their experiences?
Shouldn't this be in the WaterAlcohol Injection forum too?
Thanks,

Keep in mind this process will work with any kit as long as you have the AEM and a way to read the pressure in the line via pressure sensor, there are several different ways you could impliment it using a 0-5volt or simple ground source. You could also impliment other safegaurds in line with this one it all just depends on how creative you want to get.
