Check this thread for more info; http://www.nissanpatrol.com.au/forums/showthread.php?595-Reading-and-erasing-GU-Patrol-fault-codes&highlight=erase+fault+codes

GQ Patrol diagnostic link connector will be in a similar position (under the dash on the RHS) to the one in the photo in that thread.

Hey mate - and if it's not there, would it simply be tucked up in the cluster somewhere? Tried to find mine and no go ....

I was going to buy the lead from ecutalk.com.au, but ended up buying from a dodgy looking website, http://www.dinodirect.com/nissan-consult-diagnostic-interface-currency-AUD.html.

26bucks +free delivery (BARGAIN)
EcuTalk cable 75bucks + post

I didn't like the look of the EcuTalk Cable, the wires going into the plug looks like a backyard job unfortunatly.

With the DinoDirect one you will have 2 buy a serial to usb lead, which isn't that dear. Unless your laptop still has one of those old ports.

Don't think it came with software but there is free software on the net you can download.

first things first I had no idea that a 92 gq had this capability, so after reading this thread I thought I'd look into one of these eletronic diagnostics thingys since I drowned my truck in a river and have all sorts of electrical problems now lol
Can you guys make it clear for me...
You buy the cable that plugs from your truck to your laptop
Download free software that tells you whats wrong???
then go get it fixed

You can read certain information from the ECU and its easier to read fault codes using software and a laptop, I would not say it tells you everything that is wrong, I have not really played with mine 2 much. But for the price i think its worth getting one, you can get a cheap one like i did, or go something a bit pricier and have a permanent readout display mounted in the vehicle

not received mine yet, the posted it a couple of weeks ago. Sent me a tracking number which says International on Aus post, but there's no details against it. In fact if I type any number in with the same first and last 2 characters it says the same thing. The automated response with the tracking number is poor English, so I think it might be coming from China or somewhere.

Like I say, that tracking number just says international on Auspost and any number with the same first and last 2 digits says the same. The live customer service does not work, no-one ever there, no email addess and no telephone number, so raised a claim through Paypal now.

Very funky though (by the way) that it can be used for litres per hundred, total litres used, speedo, etc ... was a bit of a challenge connecting it as I'm running windows 7.0 and the serial adaptor doesn't have drivers for it (thanks for telling me that before I bought it Dick Smith!!!). Got around that though ...

Going to go down to Derek's on Friday (in Melbourne tomorrow), and get him to run his - measure and gather details, then run this one and qualify what marries up to what so I know what I should be looking at - I'll post up a bit of a "users manual" once done for everyone else to use.

I was right. I just checked ECUtalks website and found this;

"Adjustments
Important – USE ADJUSTMENTS AT YOUR OWN RISK.
Adjustments are available for fuel and ignition timing on petrol vehicles only. Adjustments are applied ‘across the board’ and starting in v2.03 firmware, are active whilst on one of the main sensor/trip meter screens, along with the adjustment screen itself. The adjustments utilise the ‘active tests’ available via consult. Note: It is unknown if there are any situations/conditions that the ECU may not apply the active tests, as the intention of the active tests is primarily for diagnosis.
Fuel % - Adjusts the percentage of nominal fuel (that would otherwise be used) that gets injected. E.g. 95% means the mixture will be leaner, 105% means it will be richer.
Ignition Timing – Adjusts the ignition timing in advance (+) or retard (-) of nominal ignition timing the ECU would have used otherwise. Note: All cars support retarding timing, but not many support advance of timing."

Thanks Tony

Bigrig
24th March 2011, 07:56 PM
Tony, question if I may.

My rig's timing is advanced 4 degrees (is that the terminology?), and apparently being dual fuel, I was told the engine will "ping" if it's advanced too much in favour of gas. What does this actually mean (the "ping" bit) and do you reckon if I advanced it using ECUTalk 1 degree at a time till I find "the sweet spot" that it would affect performance that much on gas?

Ok, ok ... Two questions!! LOL

Thanks in advance.

YNOT
24th March 2011, 10:10 PM
1a (short answer), Pinging is the sound the engine makes when the timing is over advanced.
1b (long answer), Normally in a 4 stroke petrol engine you set the ignition so the spark occurs a couple of degrees before top dead centre (BTDC) on the compression stroke, which means that the flame front in the combustion chamber is propagating as the piston finishes rising in the cylinder. Setting it this way ensures that maximum combustion pressure is achieved at TDC for best power. If the timing is over advanced maximum combustion pressure will occur as the piston is still rising on the compression stroke which causes a knocking or pinging sound as it tries to push the piston back down the compression stroke rather than down on the power stroke.

2, High octane fuels like LPG can handle a bit more advance, the downside being for dual fuel cars like yours that you have to comprimise the timing for both fuels. With the ECUtalk you will have the abillity leave the distributor timing advanced for LPG but retard the timing back to normal through the ECUtalk when you run on petrol so you don't have to comprimise for either fuel.

1a (short answer), Pinging is the sound the engine makes when the timing is over advanced.
1b (long answer), Normally in a 4 stroke petrol engine you set the ignition so the spark occurs a couple of degrees before top dead centre (BTDC) on the compression stroke, which means that the flame front in the combustion chamber is propagating as the piston finishes rising in the cylinder. Setting it this way ensures that maximum combustion pressure is achieved at TDC for best power. If the timing is over advanced maximum combustion pressure will occur as the piston is still rising on the compression stroke which causes a knocking or pinging sound as it tries to push the piston back down the compression stroke rather than down on the power stroke.

Thanks a million mate - on the last paragraph I'm not quite with you. Are you suggesting I use ECUTalk to advance it for gas, but then I have to use it also to retard it for fuel?? That is, I'd have to have the unit in the car all the time??

Sorry, one more - so in advancing it for gas, as per my original question, should I do it 1 degree at a time and test drive after each change to find how far I can advance it???

Not quite, there are 2 ways to do it.
1, In post #86 you said your timing (distributor timing) was advanced 4 degrees (I'm assuming that was done so it runs better on LPG). If you leave that as is then your base timing is for gas and you then ECUtalk retard it 4 degrees for petrol.

2, Reset the timing back to standard so your base timing is for petrol then ECUtalk advance it 4 degrees for LPG. That is how I would do it.
If you are finding that it runs OK on petrol at 4 degrees advanced then leave it there (as petrol base timing) and advance it 1 or 2 degrees at a time for LPG until it just starts to ping - turn the radio OFF for this, then retard it 2 degrees to stop it pinging. If an engine is allowed to ping for too long engine damage will occur so be careful.

Thanks mate - might play with that Saturday morning as I'm still not quite with you (only on the base timing etc bit - didn't think you could set it differently for either fuel source).

Digging up an old thread,

Roofy, did you get yours and did it work?

boggy2006, havn't seen you on here in a while, hope all is well, same Q for you if you see this thread

Cheers

hi ya toddy got it never used got the 3l now so i dont really need it now
thanks mate for your interest
