I am just wondering what is the minimial voltage require to power on a pionner head unit? Sometime when I switch my car to ACC the head unit is not power up?

I checked my voltage of my battery through my turbo timer when the key is on ACC. Its reading something like 10.8 to 11.99.

There cant be any problem with the connection as if i turn on the car off and again a couple of time, the power of the head unit come on..

Hope someone can answer my question as it pain to drive with out music

cheers

as I said to you in person. the whole thing will have to come out and from there it can be diagnosed. honestly sounds like a bad connection to me. the face dropping down is what baffled me as they generally don't do it. most of the raidos wont operate below 11v and if they do its not for long.

Will call u sometime to organise for you to come down to have alook at the same time fix up my sub and amplifer.

Is it normal for the battery to have less than 11v when on ACC?

What should be the normal voltage of the battery if on ACC and not engine not on.

If my engine is running the battery is reading 13.76 - 14 v

What do I need to get or do inorder to make my battery have 12v when it on ACC??

Would like to get all the stuffs required by you ( maybe those that u dun provide ) ready

Cheers

yer could be the battery... maybe its not taking full charge on its way out like ben l said check the voltage directly from the battery... i member my wagon used to cut the amps out then the radio when it was low so yeh id pinpoint it on the battery... do you drive the car alot or only once a week or so??? had any recent electrical mods that may be drawing more power and possibly drawing power when your car is off??? wen i bought my other car it hadnt been started in two weeks or so and the alarm drained the charge... usually once the battery has been drained real slowly you can kiss the battery goodbye its not worth the inconvenience

i the battery is new and the battery voltage is measuring 11.99... I only drive the car during the weekend and most of the time when i first start the car from home, the head unit works.. Then if i start it again from some time later in the day, the head unit just dun start...

If i switch to ACC a couple of time, the head unit works again however without images.... Then I need to pull out the face unit and attach it back and the images come back...

Chris Rogers said that it might be something to do with the connection of the head unit which i guess he is right...

I am goining to call him up when i sometime to fix it up hee hee....

He is good!!!!

I usually run my HU's directly from the battery (well, with a fuse etc) because I've found sometimes the normal wiring doesn't give enough power.

Also the Pioneers are funny sometimes. Both of mates have them and they do funny things like that with power. Try running a fused power cable straight from your battery and leave the ACC hooked to the ACC as per normal. Reset the thing as well.

Good luck.

i have a similar problem... the flap on my hu sometimes will not go down... i need to check the earth as i think it can also effect the head unit...

My Flap will go down everytime I off my engine ... Then it will close up after a while ( like a few second )

So are you still using the Pionner HU now?? Does running a fused power cable straight from the battery fixed the problem for you?

Cool will ask chris roger to do that for me while fixing up the amp and sub

Thanks

Yes I still use a pioneer. I don't have the model that has the motorised face that's in my flatmates car. I never had this problem.

Chris knows what he is doing you can just leave it to him :P

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

      You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!

      http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.

      Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?

      Intro/R33 owner

      By f00stx · Posted

      Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).

      Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
