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...

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:

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

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
