Wastegate solenoid removal

[Paul Clark]

Don't use it. Can I get rid of it?
Someway to avoid setting a code?
Thanks
Paul

If your chip doesn't require it, take it off. I don't have a wastegate solenoid anymore. With a MaxEffort chip you don't use it.

With a stock type of chip, it will throw a code unless you leave the wires plugged in.
Several chips do not require it as Geoff mentioned above.
What are you using for boost control in place of the WG solenoid?

Just repeating what I was "told" to do.
Someone much smarter will have to explain the details.

Tuner style will result in slower spoolup, will be very controlled, but slow. Tuner style is exactly what it sounds like...tuning only or problem determination.
Tuner style causes all of the boost generated from the compressor side to directly press against the WG actuator diaphram causing the puck to open prematurely.
The solenoid allows the computer to bleed off that pressure in the vac line allowing the boost to begin pressing up against the WG actuator diaphram at a later point once a certain psi of boost is reached and also depends on how quickly the turbo spools.

The solenoid in combination with your chip and WG rod adjustment can be used to give you optimum spoolup and precise boost control over any other device. The closest thing to get as good of spoolup is using the RJC spring/ball valve but I could still produce better spoolup using the solenoid.

Sounds good to me.
Does the HD WG screw things up?

this is just plain not true....there are many cars out there using the "tuner" style of wastegate control with great success....those could include anyone running a FAST or ME chip (no solenoid control)

my boost control is excellent using the RJC bleeder.....there are no downsides to this method......all the fastest cars here in Phoenix (including a few 9 sec cars) use this method

You can use a 100 ohm 2 watt resistor in place of the solenoid to keep the error code away, but if you put it in the solenoid connector and then tape over it, it really isn't much smaller than just keeping the solenoid wired in.

Should I get one?
Alky kit being installed now (when I get back to the garage)
HD WG/Actuator
Tuner style.
Thanks

[azgn]

why not?

 

[Paul Clark]

Fair question.
But I don't know what it does, how to use it, or what the results might be.
Thanks
Paul

the valve goes between the wastegate and compressor and is used to adjust your boost......it will keep pressure off the wastegate until the preset boost level is reached and then maintain that boost level .......you adjust your boost by changing the spring pressure in the valve...very simple and effective

As I point out at the bottom of my post, using the RJC valve will increase spoolup over using straight tuner style with no valve. Yes, there are a ton of cars running this method with the RJC valve...straight tuner though will be extremely slow spoolup on a near stock car without a huge stall convertor since any boost will directly affect the pressure on the puck arm.
