ALS valve sugestion.

[vcosmin]

Hi, i am searching for a ALS valve, with the folowing specification, 12v-14v , 25mm (minimum inside diameter), default closed position - 3-4bars. I have something on the car , but even if it has 1" input / output , interior diameter, is much smaller. Open to sugestion, something on the shelf preffered. Stock ISV valve is to small.

Here is what i tried (an electrovalve used for Air / Water, etc - 12v coil) .

What kind of medium do want to control? Boosted air into the manifold? Look for EGR control valves on newer (diesel) cars.

Some use audi tt throttle that is with wire and electro motor operated. So the set it up to open at certain amount.

Found a dedicated solution, waiting for a price.

Hope is not $$$ , as it seems, quite simple.

Search for Tibuc if you want the real deal. Swedish firm based on developing these solutions for motorsport purposes.

some people uses kicker solenoids to open throttle when needed:

What connection to you use there? Simply apply 12v to it?

[nervas]

just use AUX output from ECU and feed the solenoid with 12v

I have these spares

pin1 mcp3208 pin6,ch5
pin2 mcp3208 pin7,ch6
pin3 mcp3208 pin8,ch7
pin4 EC36 pin 34 (power out)
pin5 EC36 pin 36 (power out)
pin6 GND

I receive the price quote today, around 380-400e for the UK one. The sweedish one, seems to be twice that price, for a quite simple design as the first one seems quite expensive, better to find a home made onea

A question about the stock ISV: is it too small in general or the the amount of antilag you get with it?

Apparently some had success with these valves but supplying them with 12v led to jammed open valves.

I was thinking that maybe it will be better with the latest vems fw that allows nice control for the isv! Maybe that way I would find a use for it :-)

it is too small in general. Maybe if you will use 3 of them, then it will be enough
