Hey Scott,

I have a few points:

1. Was this problem occuring BEFORE you did the upgrade?

2. Is your BOV aftermarket? If it is, is it venting to atmosphere? If it is then thats a BIG NO NO!!!!!!!!!

3. Check out this link:

It is a mechanical service but may fix your problem (I had to do it)!!!!!!!!!!!!!

Hope I provided some insite for you :ph34r:

yeh i pretty sure thats to atmostphere then mate

if its plumbed back there;ll be a little tube which takes the air from the bov and plumbs it back into the system..

with an atmo it gets rid of the air all together (into the atmostphere - hence "atmosphere") and the afm goes holy balls where'd that air go and shits its self.. (basically :ph34r:)

wat do you mean by atmosphere?? i just got a turbosmart bov with that trumpet looking bit on it!

If it is the trumpet turbosmart then it will be vent to atmosphere.

Vent to atmosphere = the LOUD wank/illegal pppssssttttt noise you hear from the BOV in between each gear change!

Mate that can really be the cause of your problem. The stock ECU relies on the air that is vented from the BOV being recirculated back into the intake

yer tru, cause wen i got my front mount and intake done they removed the plumb and stuff, so if i put in like a hks ssq bov will that be better for it?

Let me save you the expense by telling you this.

Your stock BOV is PERFECTLY fine for the power level you will be running with those mods.

I am running more than double the factory horse power on my car with still the stock BOVs. All day everyday no problems :D

Put the stocker back in and plumb it all back again into the intake. Keep it legal bro.....don't give the cops a reason to pull you over!!!!!!!!!!!

If your mechanic reckons you need an aftermarket BOV and that you can vent to atmo with your stock ecu.......then they need to go back to the mechanic school 101 class :ph34r::D

Whoever did your BOV install MUST give back to you ALL the items he/she took off the car during the install. Every competent mechanic will just pop it all in a box in the boot of your car.

You are going to have to get the original stuff back from them other wise you are going to have to spend some more money to do one of the following:

1. You go to a wrecker and get all the factory hoses, etc to fit the stock BOV back on.

2. Turbosmart should provide as an option part to convert you BOV to return. This means a pipe/hose can be run back to your intake.

To round up:

1. You MUST feed the BOV venting back into the intake.

2. If the problem still persists (unlikely) Clean the AAC Valve.

The reason they said u need an A/M BOV is because they were to lazy to make a new return pipe for the vented air (when installing an A/M IC it's easier to put on an AM BOV), If u want the A/M BOV on there clean your AFM, AAC valve and every time your about to stop (going about 5KM/H) give it a touch on the accelerator peddle.. i would recommend going back to to standard BOV as you don't really sound like your that confident working on your car.

Before you do a mod research, research, research.... even if your mechanic says you need to do this, this and this to get ...

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 馃
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
