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.

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

      ER34 AT ECU and HKS SLD pins

      By GoHashiriya · Posted

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
