Greddy profec A solonoid wanted(sorted)

[RoyalDutchie]

As title looking for a solonoid which fits to a "mk1" greddy profec A.

That's the big silver unit isn't it?

Not sure what is in the stockpile but I can have a look.

 

[RoyalDutchie]

it is yes.

 

[Jay]

Will have a scan.

Near sure Skiny made off with my last one but worth checking!

 

[RoyalDutchie]

Thx Jay. Seems they are getting more rare these days. Did read something about them being error prone, know anything about that? If you can't find any I may try to engineer something that is compatible with the I/O of the controller.

 

[Jay]

From memory they didn't gave anywhere near the hassle that the Profec B solenoids did.

There's still a few floating around Japan so I'll keep an eye out there too.

 

[RoyalDutchie]

I know there is one on ebay for 45gbp ex shipping but the seller is not responding.

 

[SKINY]

Will have a scan.

Near sure Skiny made off with my last one but worth checking!

Guilty lol, has my other 1 landed yet

Has anyone opened one up? They're likely just a three port mac style solenoid inside.

Agreed. I'm sure a Mac (or other 12v dc solenoid valve) would be perfectly fine. If you have the connector, then it is even easier

 

[SKINY]

4 ports on them and the connection is 9 wires, the Profec B you can run a Mac valve from as it's only 2 wires to the solenoid
The A is an excellent wee unit, completely transformed the way the GT drove, cant wait to get 1 into the Dina and turn it up a bit

 

[dac69er]

Is it a pressure sensor and solenoid all in 1? That would account for the ports and wires.

I imagine it's a standard 5v sensor which you could get off the shelf as long as you know the range

 

[SKINY]

The solenoid takes a vac pipe too then passes it to the controller then it does its thing, will get pics soon

 

[SKINY]

Not sure what the bottom port is for I've never found reference to it, even the Greddy instructions dont mention it

 

[dac69er]

im guessing the small port is your vacuum port?

then the other 2 pipes are for the solenoid and the final one is the exhaust?

im not quite sure why it has so many wires though!!!!

 

[SKINY]

Yea the wee 1 goes to the manifold T into the dump valve then the others for turbo nipple and actuator
Wires are likely for the pressure sensor and acuation off the solenoid, theres +&- in there too

 

[RoyalDutchie]

Probably some old tech that required many wires to operate the valve due to a restriction in the controlling unit or bleeding valve back then. Wil check what is inside one of those solenoid ones I get one.

 

[dac69er]

Pressure sensor should be 3 wires, maybe 4 wires at a push, then 2 for the solenoid.

Would be interesting to see what the others are actually for!!!!!?

 

[RoyalDutchie]

Wil post a diagram if I ever get one. Japanse engineer can make some very weird solenoid which may require more wires.

 

[dac69er]

just did a quick search as I was wondering if it was a stepper motor as opposed to a solenoid.
It appears that it is, which would explain the extra wires
