What Is Normal Behaviour Of Front Torque Gauge?

[Gareth]

I have just recently purchased my first GT-R (an R32) and was wanting to know if the way the front torque gauge is behaving is normal, abnormal, or whether the gauge is just abit dicky (like many a skyline gauge)

So with normal driving my gauge sits anywhere from 0-10%, like i'm driving on the freeway at 100km/h i look down and the gauge is sitting on 10 (or 8 or whatever) and it seems to stay at that position until i completely release the throttle which (after a second) causes the gauge to drop back to zero.

yesterday i tested the 4wd (as i didn't actually know whether it was working) so on a wet road i did a couple of moderate launches, gauge shot up to somewhere around the 40 mark and i got bugger all wheelspin so i presume it is working. also experimented with the 4wd controller which definately was working as on zero the rear was more twitchy and on around 7 it felt really good and could really put the power down on corner exit

So does all this sound fairly normal? i was expecting gauge to pretty much read zero in all normal driving conditions and only show anything when giving it some stick.

Thanks

You have an aftermarket attessa controller, what makes you think it will react 'normally'?

This is a correct assumption -> "gauge to pretty much read zero in all normal driving conditions and only show anything when giving it some stick"

Unless you have the 4WD controller turned on/dialled up.

100kmph on the freeway should not read 10 on the torque dial. (In my experience anyway)

Your G sensor is receiving a signal which is erroneous.

If the road you're driving on is bumpy then the car will send more torque to the front wheels. On my car, if I'm driving down a shit road under power, the front wheels get's to about 10 and hangs around there for 5 seconds or so once the road gets smooth.

The workings of ATTESSA has been done to death. A search of these forums should get you an answer to your question.

thanks for the helpfull replies. I should have noted that the gauge observation is when i have the 4wd controller turned to 0.

seems like the 24 year old g-sensor might be playing up.

I'm sure attesa has been done to death but i couldn't find anything helpfull (the search function is pretty hopeless on this site) i used to have much better results just using google with skylinesaustralia (followed by what i wanted to search for) but google has changed and no longer gives the 'more results from skylinesaustralia.com' thing to click on.

You put in the search field:

I just did a Google search for "torque gauge attessa". Top of the list - this thread. But also there was a link to another thread on here, and a link to the wikipedia page for attessa, which describes how attessa works.

Both these items should lead you to the conclusion that a constant reading on the torque gauge is generally caused by the rear tyres being smaller diameter than the fronts, indicating a "slip" condition to the ATTESSA computer.

if you are running 2 different size tyres on front to rear.
i had the same problem in my stag, change to the same rolling diameter and it should read 0

Exactly this.

Check tyre diameters front to rear, I'd be willing to bet a variation there is where the issue lies.

I enjoyed that article....thanks...

been watching a few r32 acceleration videos on youtube and it seems as though 10% on the gauge is normal under full acceleration so at least i know that's normal, it's just the reading i'm getting when cruising at 100km/h thats strange

the rims and tyres i have on there are all identical with similar wear, i'm going to try put a few psi more into the rears and see if that makes a difference,

thanks everyone.

Hi, sorry to dig up an old thread, but did you end up finding the solution?

[Gareth]

Yeah i calibrated the G-sensor as per this thread and it sorted it out. Doesn't look like the picture is working anymore, I thought i had it saved somewhere but i can't seem to find it.

 

[Gareth]

Found the pic, knew i had it somewhere!

Nice!
