VEMS and TurboSmart Solenoid

[A80Avant]

nice
sorry,i havent had the chance to check the other valve i got.
i had to run on other issues and havent got the plug either yet.

Good find! I like the idea of a 4-way solenoid over the 3-way one.

Do you know if there remains pressure between the solenoid and one of the WG entry nipples, once there is no pressure coming from the turbo?

Right i'm going to try using the 4 port valve with VEMS, will try going to 1 bar 1st. Just got to get my head around PID

jamo on vems there is a realtime display. use this to set pid. same as its used to set for idle. its in a menu on megatune. IIRC add 2% to the value shown in the box.

not sure if this helps or not. hard to explain

Cheers I'll have a look, I don't know megatune at all as I did all my messing in vemstune for the higher firmware

I need to play with idle as well, never ending list

go tuning-realtime display. uit has ait DC % but not boost DC%. boost tuning will be a manual thing.

Jamo do you have a valve already? I have got 13 in stock with fittings.

Cheers.

I do

[Jamo]

if you buy a valve direct from a supplier here's how to check your fitting type:

The mac valves come with 1/8 NPT and 1/4 NPT as standard not BSPT

Check the code number to find out what type disecting the code

For example my valve is 45A - AA1

Where AA1
A = 4 port
A = 1/8 NPT
1 = No flow controls

For the valve to be BSPT it would be AC1

A = 4 port
C = 1/8 BSP
1 = No flow control

See http://macvalves.com/ products for a breakdown of your valve

i am going to try out a 4 port. it has A/B ports and Ex/IN as well.

i am going to go with the turbosmart pdf connectionwise. is that correct?

[Jamo]

Yeah thats the same method but I wouldn't buy a 4 port if you have 3 port solenoid already
You can use a 3 port in the same method to top and bottom without the boost tee, boost in to one valve and then it switches it to top and bottom



The only difference is the solenoid blocks boost on the line with no vent.

Try that 1st IMO

[A80Avant]

trouble is i have already a 4port which is new and i know it should work, and i have 2 3port ones which i believe are knackered.

i may have a loaner soon on a 3port one to try, but while waiting, i have a bit of hose and thought to hook up the 4 port see how it goes.

[Jamo]

oh ok i thought you were buying one, if you have it already it fut it!

[A80Avant]

did you find that you had to change the DC or settings too much when using this 4 port instead of the 3 port Jamo?

[Jamo]

I didn't set DC for boost control when I 1st installed VEMS only PID, but yes it had to be reduced
