Question about Turbo Timer for Nissan GU

Be careful if you walk away from your vehicle with the engine running, a friend of mine got booked for it!

Hi there Funbar, I had the exact problem 7 months ago with a turbo timer that i bought from autobarn, and it tripped out my sub tank as well. The bad new is that there is only 1 turbo timer on the market that i could find that is suitable, which is an " ARB ". It is a plug in that acts as a sort of double adaptor for the wiring harness on the steering column. I think from memory it cost me about $150 or $160. But i guaratee it will definately work. I just about pulled my hair out over it, and when i ripped a fart up autobarn for selling it to me and blowing $$$ with an auto lecky they not only refunded my for their crap timer, they even installed the ARB ( which i had to purchase from somewhere else ), for me for free !!!

So there is light at the end of the tunnel for you, but be sure that they get the right one as there is 2 types of timers that they supply........ 1 with sub-tank, and the other without !!!!

Hope it helps you out

Hi,
Mate of mine had this happen to his 2003 GU with an ARB timer.
Turned out, all we had to do was reset the ECU - disconnect battery for 3 minutes (I think it's 3), reconnect & all was good.

I have a Bogaard connected to my 2002 GU & had no such drama.

I thought Nissan had already fitted a turbo timer to those early GU patrols. It activates permenantly at about 70000 to 100000 kms.

I went to have one fitted to my 4.2td -99 and the diesel specialist in Mackay told me that it was a waste of money as that model cooled down really quickly so I dident bother that was 6 years ago.

Firstly, davidta has hit the nail on the head, disconnect the battery as he described. If that fails it is likely your sparky spiked the onboard computer in fitting and requires a technician to reload it again.

This was the experience of a work colleague with a 99 GU, 2.8td.

I bought a Turbo Timer from Repco for my GU III 3.0 and had the local sparky wire it in for me, no probs. Cost me about $210 fitted. Found out later it is the same unit ARB uses, except it wasn't prewired with the double adaptor plug setup. It incorporates a digital voltmeter and the timer is adjustable from 1 second to 99 minutes 59 seconds (Why that long I'll never know).

Hope this helps,

Cheers!

Hi Fubar
The Old Turbo Timer Timed Turbo Cool Down trick hey!
Cool though it doesn't always work, damn! Believe it or not I was considering one for my rig but then I met some one, let's call him "Dave". His rig was the same as mine a Patrol Gu 4.2TD & guess what, he had fitted a turbo timer, with the same results, or rather lack of use of his sub, yes he used the cut the battery power off trick often, but he tired of it.
His recommendation to me re: the timer, was save your money.
When I have if I have been out on the H'way or F'way, downing long miles/K's I never turn the motor of when I get to the destination, I let it idle for a few minutes to allow the turbo in the engine to cool.
This could be considerred a "bit thick" in options, but hey the 4.2TD might not be the most specky in modern motors, it's winning points to me is that it just chugs along happily!
So save your money & mental duress let your motor cool with a manual idle.

madCrow, Enjoy today for we know not clearly what tommorrow brings!

Fubar,
When I bought my Boggard Timer, it had "Nissan GU with Sub Tank" written on the box, so maybe there is a different model, although as far as I know all Patrols in Australia have sub tanks.

I had a 99 2.8 TD with one fitted.... I cant remeber what brand it was but it worked just fine and had no impact on the Sub tank.. so sorry I cant help you with the brand but at least you can keep your hopes up..

Hi Vince,

The problem with most turbo timers is that they are a 3 wire joby which when connected to a GU, supply juice to only one of the accessory lines when in countdown mode. The GU specific ARB timers actually have more wires to connect to other accessory lines so that standard operation of all circuits is maintained. The reason for this is because the sub tank ECU (cause it is a sort of computer that is seperate to other electronic diesel ECU's) has around 3 power supply lines going into it. There is a constant 12V line and 2 accessory lines. The problem is when a non GU specific turbo timer is fitted, only one of the 2 accessory lines is powered in countdown mode which sends the ECU into a spin and goes into fault mode. To reset this fault you disconnect battery for a few minutes. To fix the issue you need to power the other accessory wires via a ballast resistor or diode of some sort. You need to be careful though that the system doesn't keep powering itself because you introduced a loop of some sort.

I investigated this a couple of years ago but never really went much further about rectifying my problem. If you get hold of a Sub Tank block diagram and circuit, you will be able to see the issues at hand.

David
