Attesa Always Sends Power To Front When Accelerating.

[PHATR32]

hey guys,

My 89 R32 GTR has a problem where the front tourque gauge shows a reading, all the time while accelerating. Even if im going in a straight line, real slow and touch the accelertor, the needle goes up between 0 and 10 on the gauge.

The attesa works fine, when i do a hard launch, there is little wheelspin before the front wheels kick in and it takes off. (although ive havnt been in abother gtr to compaire) Its shows almost 45 when i do a hard launch in the wet, and she takes off!

Ive got 17's all round with brand new 235 tyres on all four sides.

The only thing i can think of thats causing the problem is the wheel alignment. Due to a problem i had with my front left caster, i wasnt able to get the alignment done. I think ive fixed the caster problem, but havnt had the time to do the alignment yet.

Any help would be great as i dont want to burn out my clutch packs!!

Also, I have done the search but found nothing usefull.

thanks

Steve

This is the way that ATTESSA works, it puts some drive to the front when accelerating, even in a straigh line. The accellerometers measure your accelleration and put soem drive into the front wheels, keeping the system primed also allows for faster response when it is needed. You will notice that you get no front drive when decellerating also..

Sounds very normal to me..

ATTESSA takes input from rpm as well as wheel speed differentials as well as gees. Sit still, blip the throttle & you should see the gauge move. Means you get some front wheel drive action immediately on clutch dump...

yep.

throttle

gee force

revs

steering

and wheel speeds/differances all make the guage move.

thats normal dude. sometimes they get abit confused when you go over a bump it will jump up to 30-40 untill you back off

meh. still hooks up but

I agree, it all sounds normal to me.

There is a slight possibility that the G sensor(s) are playing up and are too sensitive.

Duncan's ATTESSA controller intercepts and modifies these signals so you can increase this sensitivity to what you want. I don't think that it can DEcrease sensitivity, however.

weird, I was under the impression attesa "kicks in" when it senses the rear wheels slipping, by using the abs sensors.

It does. But it also has 3 G-sensors (1 longitudinal and 2 lateral), and it also picks up on the output from the TPS.

Cool, thanks for that guys. I now 1 got one less problem to fix!

exactly, but like all interceptor ATTESA controllers it won't affect straight line torque, nissan designed ATTESA to give max front torque in a straight line and progressively less FWD the more you are cornering.
