I assume the kit you are looking at is one of these:

If the Snow kit can see a pulsewidth-modulated signal as a variable voltage, then you might want to use their MAF Variable Controller. You could probably set one of the AEM PWM outputs to send a duty cycle based upon load/RPM somehow and use their controller to control the water/alky flow.
I haven't done it, and haven't researched it - but I would guess you'd want to look in more detail on how that would work. The AEM forum folks might be able to help if you tell them specifically what you are trying to do and what items you want to use to accomplish it. |
Thanks mjannusch
The Snow MAF controller can see a 0-5 volt signal and can adjust flow to increase the alcohol injection the voltage increases from 0-5 volts. Can the AEM output a 0-5 volt based on a manifold presuure signal? In other words can it say: when the manifold pressure is 10psi put a output a voltage of 1 volt then when manifold pressure inceases to 11 psi then send an output voltage of 1.5 volts and keep increasing output voltage as Manifold presure increase all the way up to a maximum of 5 volts.
IN other words can the AEM vary its output votage 0-5volts base on the increasing MAP sign that it sees coming for the AEM MAP 3.5 sensor?
