My AVCR solenoid is mounted behind the drivers side wheel arch and it's loud and annoying. Also I've been told that the length of hose running makes it slower to react.

Pic one is where it's mounted.

Pic two is the pair of tubes running all the way around the engine.

Pic three is I think the t-piece where the boost controller taps in, so to speak.

Can I safely cut the wires shown in pic one and run longer ones around the other side of the engine? What spec wire should I use if this is ok? (I always get confused at Jaycar, there is too much wire to choose from.)

Do people think this is worthwhile from a response perspective or am I only doing this to get the noise further away from me?

Got boost - Thanks, I should have been more specific. I know the fuel filter.

ronin - boost gauge sensor sounds right.

SKYL9 - I think it does but I didn't install it. I think I may fix it when someone tells me what's what from my first post.

You can cut the solenoid wires and solder in a length of wire to suit. I did and its not a problem. As for the type of wire, i used 0.5mm unifilar wire.

And yes the little black fitting with wire and hoses is the MAP sensor for the AVC-R.

But the easiest fix is to get about 3mm thick rubber and mount the solenoid on that. Or even better is do what i did and make up a simple aluminium bracket that bolts off an existing hole and combined with the rubber you will never hear the solenoid.

As for the length of hose, there is some merit to that thinking. However if the thing is holding stabel boost and is repsonding well (not spiking) then the length of the hose is not really effecting anything.

More important is the diam of the hose.

My suggestion is, remove all the existing wiring, and make up a simple aluminium bracket that bolts to the back of one the power steering reservoirs. It will shorten the boost/vacuum lines significantly, as it will now sit 6-8 inches from the actuator. The std length of wire is fine if you run the wire thru the firewall with the ECU wiring.

...and dont forget the rubber mounts:)

Thanks Roy.

It does spike and that's partially why I was interested to know if this could be the reason. Also it spiked on Sunday to 0.92 bar which resulted in a blown turbo.

It already has a rubber mount but I had exactly the same idea as you with a an alluminium bracket.

So I wont need more wire if I rewire through the passenger side of the car?

I might as well do all this while I'm replacing the turbo. I had hoped to have it out already but there is a bastard alan key bolt holding my dump pipe on to the turbo.

Damn, shame about costing you a turbo:(

But in which case do the bracket behind the power steering reservoir. You will be able to get the lines nice and short. Also use the correct diam hose, if you use the larger 8mm hose then its harder for the solenoid to control the boost.

Depending where they run your wiring in the dash, it may take a bit of tweaking, but the std AVC-R definitely has enough length in its wiring to run next to the ECU harness thru passenger side sill.

I mounted the MAP sensor over near the brake booster, so once again the vacuum/boost line is short as possible, as if this line is overly wrong then in theory it could also dull the response of the controls/AVC-R. That was the wiring that i had to extend a few inches so as to allow me to keep the boost/vacuum hose short as possible off the inlet manifold:cheers:

Good luck with it

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
