6pt and VDI questions
Hopefully you guys won't run me off
I have an S5 intake system I will be running in a REPU project. I have a megasquirt to control the fuel and would like to use it to trigger 6 ports and VDI.
Looking through the FSM looks as though the 6 port actuator is fully open at 1.4PSI and the VDI is fully open at 2.8. The air pump checks out at 1.7 at idle. I can only assume the air pump produces more pressure with RPM. I have followed the line routing in the FSM and do not see a pressure regulator for either system. I may just be over analyzing.
Before posting my WTB thread I would like to make sure I am not missing anything. Are the VDI and 6 port solenoid valves specific to their function or can I use any of the stock 6 solenoid valves? Is there a pressure regulator for the systems?
Thanks for the help.

Correct.
It didn't need one because the air pump is pushing air into either the exhaust ports, cat or relief hose. The system is basically open-ended, so pressure can't build up. If you only use the air pump for the 6PI and VDI systems, you'll need an adjustable bleed to create a leak that'll prevent over-pressurising the lines. A simple ball valve is all you need, with a bit of experimentation to see how much of a leak you need.
