Help, 4wd Torque Gauge Reading On Cruise

[sky30]

Just want to know what figure the stock torque split gauge in the dash sits on when cruising at 90-110km/h in 5th gear.??

Mine is nearly on the second dash at 100km/h, i cant remember if this is normal or not, when i cruise at slower speeds say60-70 it sits on the bottom.

Moved to here for ya dude, more suited to drivetrain i feel

Cheers!

Here's a vid of a BNR32 at the 'ring.

No idea if it's modified or not, but lets you compare torque and speed as it progresses around the track.

The torque transfer to the front wheels goes up heaps if the rear tyres are smaller diameter due to different size or wear, as the computer thinks that the different axle speeds are constant wheelspin, or you could just get one of the awd controllers, it cant be helping your fuel economy

at 100km/h i on the first dash , slower speed on the bottom

Mine sits on 0 at highway cruise (in fact, any-speed cruise). You probably have a reading because the rears and fronts aren't matched sizes and the ATTESSA computer thinks you have a bit of wheelspin. Try swapping the fronts and the rears and see what the gauge shows.

Same as blind_elk here champ. When I had smaller dia tyres on the rear it was a pulsing torque reading and through the pants feeling.. not just a constant reading.

Any error codes on your attessa ecu?

My rear tyres are a different brand (but same size 235/45/17) to the front tyres and are a little worn, fronts are new.

I was wondering if it has anything to do with my new motor( rb30det) combo ive just put in the car, as before when i had the stock RB20 i dont remember the gauge reading that high.

How do you get fault codes from the attessa ecu, is it located under the parcel shelf?

[heller44]

The tyre size issue that i had was with 235/45/17's both ends, but new ones different brand on the front. Same as you seem to have. Just swap them front to back and see if there is a change.. easy. The difference old to new and different brand was enough to make mine go nuts.

Attessa codes are read from the module in the boot. There is an indicator led on the housing that you read codes off simillar to an engine ecu.

I have attached the ets diagnostics sheet, maybe that will help.

does the attessa do anything when entering corners?

My rear tyres are a different brand (but same size 235/45/17) to the front tyres and are a little worn, fronts are new.

So the rears are smaller rolling diameter, and causing the ATTESSA ECU to think that you have wheelspin. Also, just because the tyres are "the same size" doesn't necessarily mean they have the same rolling diameter.

Swap the fronts and rears and the gauge will behave itself.
