how to wire up fail safe to turbosmart eboost sreet?
 

hi can any one help me with wiring up the fail safe to a turbosmart eboost street? sep

I believe I used the white & brown wire off the yellow HFS-6 plug, to interrupt one of the wires to the eboost solenoid. Polarity on the solenoid doesn't seem to matter.

Iworktofish,
Thanks for the input.

sep07,
One of the two wires of the turbosmart send a PWM pulse to the inline valve. Locate this wire, cut and splice the brown and white wire between them

Preferrably the "brown" goes the the valve side and the "white" goes to the turbosmart controller side.

If the turbosmart displays a fault warning during a failsafe activation, link the "DR1" jumper link (dummy resistior). It brings in an artificial load inplace of the BCV.

thank for the info il give it a go and let yous now how i go. sep

hey richard i dont understand white wire to controller and the brown to valve side. are they wired to the same wire? whould u have some sort of diagram? thanks for ur time.

I like this thread. I just recently got an eboost street wired up on my A6, and was thinking about hooking it into the failsafe.

The white wire has the dummy load resistor on it so when the circuit opens to drop boost your controller will still see the resistor load and should not put out a fault.

If wired the other way, the resistor will be on the valve side and your controller will not see it.

alright, bringing this back. to make sure and to clarify this up for me:

white wire: to the solenoid
brown wire: to the control unit

is this correct? also does it matter which of the two wires(stated above in post #3) from the solenoid to the control unit you cut in half and complete the circuit with the white and brown wires?

Not quite, Jeff Howerton merely pointed out the function of the white wire after failsahe is triggered.

As regarding the solenoid valve wiring:

White wire: to cotroller side
Brown wire: to soldenoid valve side.

It does matter where the wire goes otherwise you will get a CEL (if you are cutting the OE wire). After cutting the solenoid (-) wire, the brown goes to solenoid side and white goes to controller side.

alright, thanks richard for the quick reply. i'll try this tomorrow. Jarrad Bowen said you do reply quickly. he said what's up btw.
