hai all,

since i can remember this has been happening, i think this noise is coming from the ecu, i have a stock ecu and at a sertain throttle this realy high pitch beep comes on, its not loud and its not that annoying but its there and worries me that its a warning beep, the noise disapears once i either put more throttle on or less, but at that sertain level it will beep untill you change throttle. i think it does it in any gear i havnt realy taken notes to it alot. has anyone had a similar issue?

cheers

please note, I THINK its coming from the ecu, it may very well be coming from elsewere, its one of those noises where you turn your head and the noise disapears lol

I don't think ECUs make noise ... as has been suggested, check your stereo setup .. I had new speakers with a crossover box installed recently and noticed the same sort of whine, apparently it was picking up engine/alternator noise. They just moved the crossover box a bit and it went away.

I get the same sound that you describe as well every now and then. Mine tends to happen at a certain engine load - I may be travelling in 4th at approx 60kmh, depress the throttle slightly due to a slight incline in the road and i get the noise. If I hold the throttle there and keep the engine loaded at that point, I can hold the noise. If I release the throttle or depress it further, obviously the load on the engine changes and the sound disappears. Kinda sounds a bit like faint feedback from speakers if you hold a microphone too close - but my stereo is never turned on.

My thoughts were that it is some sort of engine noise, possibly intake/turbo...

yea sounds alot like mine, i thought it was a boost leak or somethin, my sterio steup is pretty sound, so will have to check elsewear

Well there is that possiblity, but I have noticed that there is a really high pitch beeping type noise from the Greddy Profec B's.......

I have learnt to ignore it :D

its not actualy a beep persae, it’s a constant eeeeeeeeeeeeeeeeeeeeeeeeee

I would say that would be your best bet.

You can also see if there is a boost controlling solenoid near the turbo somewhere. If you have something like that then there is a fair chance that you have a electronic boost controller.

Something like this:

  • 4 weeks later...

mine does the exact same thing, even with the stereo off

like others hav said, if im in 4th or 5th gear at 60km/h or so and hold the throttle in one spot it will start, soon as i just increase or decrease the throttle abit it goes away, but then comes bak.... its realy weird

i dnt think its intake cos it does it in high gear, low speed and the boost needle is way down in negative land...

hmmmmmmmmmmm

    • 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.
