Wastegate Solenoid???????

[Kerry]

Can anyone tell me what signal controls the solenoid(pwm??) Also is there any reason I couldn't use a boost command from Ramchargers for a twin turbo mustang? I called Ramchargers and the guy said they would only work on a GN. I have twin Racegates.

Thanks Kerry

Come on ,,,, you mean to tell me with all these GN owners no one knows how this works

It is pulsed by the ECM, if that helps. Everyone is at the Nats, sorry.

Don't think you can use the boost command from a stang. Usually the vendors are right about their products...

Wastegate Solenoid

The wastegate solenoid is an electronic bleeder that is pulsed by the ECM in order to control boost. It functions by bypassing boost through the solenoid into the atmosphere. As this happens, the amount of boost reaching the wastegate actuator is reduced and it takes more total boost to overcome the wastegate actuator spring. Minimum boost is obtained when the solenoid is closed and not pulsed. As the pulsewidth transmitted from the the ECM increases, the solenoid is effectively held open longer, more boost is diverted thru it, and the actuator is delayed in opening so that more boost is produced before the puck opens.

Note that the wastegate solenoid has two ports...one is connected to the "Y" hose arrangement from the actuator and compressor housing. The other is open to the atmosphere. From the factory, there was a small piece of foam attached to the open port as a filter. It does not matter which port the "Y" hose is connected to.

In the plastic "y", one end has a small restrictor in it. This restrictor is connected to the compressor housing port. The hole in the restrictor is normally .045-.050". Boost control will not be right if the hole diameter does not fit into this range. Some dealer replacements do not. The function of this restrictor is to prevent the wastegate solenoid from being overwhelmed by the volume of the boost coming from the compressor port and thereby being rendered ineffective.

I could not tell if the Boost Commander mae a new signal to the solenoids, or intercepted them from the ECU and altered them.

If it makes the signal to the solenoids, you can use it as a stand alone unit.

You can use the BstC as a standalone. The MaxEffort chips provide no boost control, so you have to use a standalone and this controller works fine. I don't know if you'll be able to figure out things like 3rd gear scaling, but if you can get the solenoid lead to it and power and ground, you should be golden.

What solenoid are you using to control those twin racegates?

Doubt the BSTC will work properly with them, but it might....

Designed for the stock solenoid and wastegate setup.

Innovative controller and solenoids is more like what you would need.

I was going to look at the GN solenoids or the Diesel Solenoids. Just can't see spending $500 dollars on a controller..
