G'day peoples,

What is the go with Attesa traction control???

Can anyone out there give me specifics to do with angles, when traction transfers, how the computer dictates distribution, anything that is absolute fact.

Tanks heaps

There are a lot of sensor inputs that go into making the AWD work. There are speed sensors (hijacked from the ABS system), G-sensors, TPS and steering wheel position sensor.

The idea behind it is that the car for as long as possible acts as a RWD. This means that it has the characteristics of oversteer the same as a RWD. The designers didn't want the problem of understeer that constant AWD have (WRX, early EVO's etc...) The important thing to remember is that the front wheels kick in to assist the car and can share anywhere between 0% to 50% of the engine load.

1. Straight line. When the power is put down the front wheels will kick in to keep traction so you get the grip that a WRX has. The more you put your foot into it the more the fronts come in.

2. Cornering. This is a little tricky as it almost works in the operate way. The more lateral (side - cornering) force the car is under the less the front wheels will kick in as this would provoke understeer. Instead, it will wait until the rear end breaks loose then when you go to correct it, pull the front wheels into action so that now all wheels are working to push you in the direction you are steering. This can be disconcerting for many new GTR drivers expecting a typical WRX type AWD experience. This does allow you to still positively steer the car whithout loosing ground from the rear end slide. You keep your foot planted and just point the car where you want to go, letting the front wheel drive pull you out of the power slide. Not to say it is fool proof, you can still get bitten, but careful practice can be rewarding.

So to give you particulars on angles and so on is not possible as the whole system is adjustable depending on so many differing sensor inputs.

      I currently have someone who is interested in buying the rear set, plus he has asked me to quote him on an equivalent front set, new of course.   I'll post up what a new set would cost and you can make a decision then. I noted a bit of discussion on spring rates versus swaybar rates, Duncan has explained my approach very well.  What I would add is that if you have high spring rates then it is a PIA to change them if you want to, say, do a track day.  Whereas with adj swaybars it's a much easier task. Plus if you find that there is an imbalance in the handling (oversteer vs understeer preference for you) it is relatively easy to change the balance with adj of the swaybars, again much more difficult with springs.  On the race cars we don't change spring rates all that often, we do however change damper rates frequently, high speed vs low speed bump and rebound independently.  A tuning task not for the inexperienced, driver or engineer.  Driver adj swaybars are adj frequently, several times in 20 minute race is not unusual.   Cheers Gary

      Yes. The difference between a $1k centre and a $2k centre is not worth it when the whole exercise will cost double that anyway.

      Rebuild vs second hand NEO?

      By GTSBoy · Posted

      An excellent question. Both answers are correct. I think the reality is that any Neo you get from Japan may well be the same as any other engine that has spent too many years in Japan. That being the problem of low to zero maintenance and oil changes, etc etc. So any Neo you get from Japan should be considered to be sufficiently risky to warrant planning to pull it apart and rebuild it anyway. That's a significant extra $3.5k impost on top of doing the same to your S2 engine, and the question has to be asked, would you rather have the (somewhat small) betterness of the Neo for $3.5k, or would you rather spend up to $3.5k on even better betternesses for the S2? New ECU? Better triggering? Better oil pump, sump, cam covers, etc?

      Hi guys, I have a ECR33 97 model. Engine has a cracked ring land. Would it better to rebuild the series 2, or buy a second hand AWD 25det Neo from Japan from ~$3500 tidy it up a bit with new seals and so forth and use that?  I'm leaning more towards the NEO option but understandably they're very old engines too now, so could be just buying problems. Cheers.
