jimmy_supra Posted March 22, 2011 Share Posted March 22, 2011 After two years I have finally got around to fitting my Apexi boost controller. I have got the instructions and the wiring has gone ok. Just need some help with connecting the solenoid. Can anyone tell me which pipes to connect to and which ones to block off any pics would be great. Thanks.

There's a guide on mkiv.com under technical. Quote Link to comment Share on other sites More sharing options...

Not yet, I am waiting for a mate who tunes Audi Quattros to go through all the info. There must be members who could comment though. Quote Link to comment Share on other sites More sharing options...

Its the section in the article that describes why NOT to link the pipes that used to go to the EGBV that worries me (AVCR instructions say to do this). The article says that this can restrict the #2 turbo from pre-spooling, which is what I think is going on in my car since... 1. Theres a big dip in power when it transitions from #1 to #2 turbo. 2. Sometimes it even struggles to make the transition 3. When the turbo comes on line, its not smooth but quite powerful, enough to spin the wheels up when damp. If anyone has had the same issues or done the suggestions in the article then it would be interesting to hear about. Quote Link to comment Share on other sites More sharing options...

If mine has been removed then would you say that the Controller has been fitted incorrectly? Quote Link to comment Share on other sites More sharing options...

jimmy_supra Posted April 6, 2011 Author Share Posted April 6, 2011 All fitted and working fine the instructions for the unit did the job. I had some of them missing so printed them off the apexi website. Fairly straight forward in the end. Quote Link to comment Share on other sites More sharing options...
mellonman Posted April 6, 2011 Share Posted April 6, 2011 jimmy, just so you know you will alway have to have this unit switched on as when switched off they can cause boost problems being that it stops you making full boost dont know why had a problem with mine not making boost when unit was off so thought turbos was dead but turned out to be the unit i found this out by pluming it all back to factory and giving it a run and made correct boost levels.just a heads up. enjoy your new toy all you have to do now is set it up as you want have fun Quote Link to comment Share on other sites More sharing options...

Fairly straight forward in the end. Glad it went well, I'm going to have a go at putting mine back to those instructions. One question - Did you disconnect the pipes going to the EGBV at all on top of the engine or was all that left as standard? Quote Link to comment Share on other sites More sharing options...
neilp9876 Posted May 7, 2011 Share Posted May 7, 2011 I fitted the EGBV valve back onto my car and it feels SO much smoother with no problems transitioning from turbo #1 to #2. Happy days If anyone else fits the AVCR controller I would recommend not removing the actuator. Quote Link to comment Share on other sites More sharing options...

The boost will simply be what it is, at a guess it will be standard at 0.7 but i'm no expert on how the boost controller works. Its hard to tell but I think the power dropped a little after i put the valve back on but not by much to be honest and I certainly dont miss it, I only really need the power when its WOT.
