i bought a multi meter thingy today too see if there was any current going into the ignition and power wires for my headunit and it showed no charge for all the wires behind the headunit. I checked the fuses and they all seem ok.

How can i run my headunit so it has power but turns off when i turn the car off?

Dude you have to make sure that have 3 wires from the head unit:

+Constant (Norm. yellow or orange)

+Acc (Norm. Red)

-Negitive (Norm. Black)

but you also have to have them from the loom of your car behind the head unit.

if you have a multimeter it is easy, always keep the -Negitive prong (lead) of the multimeter on some part of the chasis of the car and then test with the +Red prong (lead)

when the ign is off you will fine one of the wires will always have a voltage (12v) that will be your Constant (Yellow or orange)

then you have you try differant wires whilst turning the ing on and of to find the ACC wire in the loom.

meh if you can undestand that go here: The12Volt.com

if u get this the wrong way around then your memory wont stay in your headunit and the cd will begin form the beginning eachtime u turn ignition on.

are your parkers/brake lights working?? if so then uve connected the ground to the parkers instead of ground (i learnt this the hard way)

if your clocks not working then u must've blown a fuse... i think the parkers fuse is in the engine bay... but the clock fuse is in the car.

I worked in a Car stereo shop for about 3 + years and It sounds like a fuse is blown.. I know you said you checked them but Id check them again.

80% of the time if your clock goes and your radio then they are on the same line.. Check if your interior light is working aswell.

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
