Solenoids

Hi,

 

I'm planning to purchase AEM 30-3300 for my mini cooper S which runs with about 18psi boost.

I understand that new nozzle has a check valve inside, instead of external check valve. But does this internal check valve have any pressure rate, so that it can prevent flowing of liquid to intake manifold while the engine is off due to gravity or siphon effect?

If not, I guess the solenoid between pump and nozzle is essential.

I'm aware that AEM offers optional solenoids which receives 1.5amp signal from controller, however I can't find any part number for this solenoids.

Can you verify the part number for solenoids?

The internal check valve will

The internal check valve will open above 22psi, closed below that pressure. We currently do not offer a flow solenoid, there are other manufacturers who sell them and will work fine if one is required.

Hi,

Hi,

Could you please point me to where the solenoid would connect to in order to work properly?  Would it connect to the power line (pink) or to the brown/white (solenoid) line?  I guess I am also trying to figure out what triggers the solenoid line to get power. 

Thank you!

The instructions clearly

The instructions clearly state how to wire in the solenoid:

Hi,

Hi,

I underestand that! I am talking about a third party solenoid that cuts the W/M mixture right before the injector.

Thank you!

Hi,

Hi,

OK! You can keep being rude I guess. 

What is the function of this wire? When does it trigger? Wouldn’t it be better to wire the solenoid to the pump power so the solenoid cuts the juice once the pump turns off?

Thank you!

You asked how a solenoid is

You asked how a solenoid is setup and you were answered twice with the same info. The function of the wire is to turn a solenoid on and off. The name of the circuit is "Solenoid -" which means it's a ground output. In the diagram you can see that the solenoid is powered by switched power. Because the solenoid is for flow control, it is on and open when the pump is running and off and closed when the pump is off. No, it would not be better to wire it differently than we've shown. Please follow our recommended installation diagram.

Thank you!

Thank you!

Just wanted to make sure you all did not have a crazy setup/trigger point for that wire. I will be doing just that by connecting the solenoid to the wire.   Have a great day.

that soleniod is opi it shuts
that soleniod is opi it shuts line off so meth don't siphen in intake charge when not being used if you look it says opi, if you mount nozzles below pump it siphens

Solenoid should be part of

Solenoid should be part of the kits. And not state "optional" as this is misleading. I mounted 3300-30 on my 20k km TTRS 2.5 tfsi DAZA motor and while starting the engine a couple of days after the installation this were the cosequences:
