Vems and 3port turbosmart solenoid

(1/1)

AVP:
Hi,

im going to try and control boost through the turbosmart solenoid valve,the one used on their electronic boost controllers. It is a 3 port valve with 2 cables that can be easily connected the same way that the OEM valve is connected.

There are various different ways of configuring the valve on external wastegate and i was wondering whether VEMS can actually control boost better through it's settings.

has anyone else ever done this?

gunni:
I´ve always used a 3 port boost control solenoid without problems.

AVP:
the audi N75 valve is very difficult to control and always drops boost on lower gears.I have tried multiple PID settings. The only thing that is left is actually a stronger spring,but i dont want something like that atm.Im hoping that the newer solenoid valves are able to respond better to the vems settings.

GintsK:
I have opposite experience. I like these valves. Only difference - using boost alternate strategy.

AVP:
for some reason on my vems, using duty cycle, never worked for me! im using basic settings with map target and sort of have it for higher gears,but i always get a boost drop on low gears towards the end of the rev range
