i have tried everything new deck , new amps , new battery ,new grounds , new cabling , moved amp around.... reinstalled while system twice and no luck its still there .

As soon as car is on its there , i switch the lights on even louder.

Anything anyone can suggest to get rid of it?

Could it be my alternator ?

I have had the amp installed professionally and even that didn't help , took it back fiddled with it and in end turned gains down way too low and even then it was still there.

Im willing to give $50 cash to anyone who can solve this problem.

Mate,

I have a guarateed cure for you. It is a bit old school but it works.

Here is what you do:

- Get a large steel shacle. About 2 - 3 inches.

- Then get about 8 or so metres of 16 guage insulated cable.

- Start threading the cable tightly though the centre of the shackle and wind it tightly through and around, throggh and around, the entire circumference of the shackle. The idea is to imaginne the shackle as a circle and you are covering the circle in several windings (or turns) or wire.

- Connect this wire in series with the 12 volt input of your amp. (add a fuse if you like).

- Start engine, turn on amp, and listen to whine-free clear sound.

If you have a massive sound system, which I suspect you do, you should use a higher current cable, and a proportionaly larger shackle. What you are doing is creating a large inductor to attenuate the whine.

I had EXACTLY the same problem in my R33. I made one, and installed it in the boot. Like I said, it is very old school, but, it works.

PM me if I have not described the process well enough, or you need more info.

regards, Steve.

Are you running power straight from the battery to the audio equipment? might be enough just to have the headunit drawing power directly from the battery, should get rid of the alternator whine.

hey mate if you are running your power wire from your battery on the same side as yur rca leads for the amp seperate them from each other my car did the same thing and i moved my power wire to run down my left side of my car and my rca leads down the drivers side and it fixed the problem

today i gave it one more try , added a noise filter to the constant 12V line to the battery. That solved my issue.

There is maybe a bit more whine but nowhere near what it was before , i guess its stuck in my head now .

But its gone no more whine :P

btw where did everyone ground their amp , pictures that would be great :(

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated. Rb25det s1 walbro255 fuel pump nismo fpr holset hx35 turbo fmic 3" exhaust freddy intake manifold q45tb q45 maf   Re: s1 RB25det flooding at start up Fri Apr 12, 2013 5:07 am No, I didn't. I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
