i also have a feeling that it's not spraying i'm going to have someone listen to it right now.. it's only on extremely cold starts also. when the car is warmed it does not do this.

This is possible due to pre-cranking enrichment. I think when the weather gets colder, the duty cycle will be higher. Dd you have this happening during summer?
The DDS3 has a start up routine, it could be a electronic noise. I think it is n=more likely due the fuel injector turning on.
It is causes starting problem due to over enrichment, turn off the system until engine was started.

Happened to my car once when I hooked the controller up to the EGR vac line (which maintains no vac) and the cotrol started to spray at idle. The car backfired and eventually idled bad, pulled out the stepper motor and it was melted to high heaven. Luckily I was able to find a complete TB/intake mainfold assembly for just $200. Was one hell of a deal being worth about 4X what I paid.
If you spray at idle the methanol fills up at the lowest portion of the TB. Ever noticed the two rectangular holes at the bottom of the TB inlet? A puddle of sprayed methanol while throttle is closed will accumilate and drain from there, fumes in combustion chamber remain and the spark ends up igniting it roasting the stepper. 06 IACS are worst too being made from plastic.
I dont know if the ignition spark or the stepper coils start it, I just know that it happens
Hey, just wanted to let others know if their running striaght methanol and spraying with TB closed.

theres a guy on here that blew up 2 magnus intake manifold with his no solenoid valve progressive pump speed system...system continues to spray until all pressure is vented, spraying even after throttle plate is shut...

Spraying with throttle closed, even with nonflamable water-methanol, is just asking for trouble. The three metal plugs at the bottom of TB, because they're dissimilar metals to TB, will quickly start a corrosion reaction and spread like a staph infection throughout the TB. A bucking DV would just make it worse
