World Time Attack Challenge 2012

[Nee-san]

I like the way you think!

Wish that was true and a skyline was up the front... Clearly the 4cyl (lighter) cars have a bit of an edge over the cars that men drive...

If you want to have a go at pro I will gladly change your tyres for you

Hi Paul,

I couldn't find anywhere to put this, Hopefully you will read this.

I have one of your #1 4x4 Controllers in my car, Other than the GPS function to plot corners on the track, What are the differences between the new #2 controller and the older #1 unit I have? Am I going to notice the difference between the two?

Thanks.

Finally got my story finished - as part of Mark Berry's crew this year with my ATTESA controllers etc. I have put it up on my website www.timeattacktalk.com

I will hopefully get the tech one written this week with data logging results etc. (still catching up on sleep )

The 4WD Controller II is a freshen up of the version I, some of the parts in the version I were no longer available so I did a redesign. The V2 has a better processor and optimised internal algorithms and the output is more accurate. Plus the GPS stuff. Its hard to say if you would notice the difference, it would depend on the rest of the car to some degree and the driver. The V1 controller does a pretty good job, the Version 2 is a refinement.

The Controller in Mark's 34GTR is a whole other story. For that car I had to design the complete ATTESA system from scratch. Mark had removed all the Nissan factory stuff, computers, sensors etc. In that car I have:

1. Front Lateral G

2. Front Longitudinal G

3. Front Gyro Z axis

4. Rear Lateral G

5. Rear Longitudinal G

6. Steering Angle

7. Throttle Position

8. Brake Pedal State

9. Front drive axle speed

10. Rear drive axle speed

The controller then takes all these inputs, does a pile of signal processing and outputs the control signal to the hydraulic system. I also added true linear output control of the valve for smooth operation (not using a simple PWM control signal).

Hey paul what is the difference between the likes of the controller being touted by Tarzan Yamata and yours, Is one better than the other r do they do the same or different things.

Now I have a working g sesnor in the car I am about ready to fit a controller.

Yes if you dont mind starting a thread I got a few Q's as well. Might get a bit off topic here.

No worries, I have started a new thread here http://www.skylinesaustralia.com/forums/topic/407612-gtr-awd-torque-split-controllers/

Interesting times in v8's compared too time attack!!

[boxheadmr]

thats pretty impressive for the tin top supercars

[fatz]

V8 taxis 60 bux for a day ticket for 2 people. Lots of raceing lots of shit in the pits

Wtac 100 bux for a day ticket not much racing lots of shit in the pits

Can someone here pass on the above info to the organisers please

I can't decide which I prefer bogans in utes or the flat cap brigade. All I know is the cheaper one is better run

It's funny because it's so true!! You said exactly what I was thinking Fatz!!! haha! Legend!

[DJRIFT]

ive checked my tv guide and there is 1 hours worth of coverage for yesterday and today at 11pm. what a joke. 7 is only running AFL and repeats of Gay factor. what a joke.

oh well sorry for the hijack.

Well Channel 9 is no better. No live coverage of the Bedisloe Cup!

I was quite surprised at how well the "2 days for $65" worked at the v8's this weekend.

Great value if you go for both days (as I did) but I didn't think many people would go on the Sunday for $65. To my surprise it was way more busy today than Saturday (took me 1.5hrs to get out of the carpark) so I guess it all worked out.

You are right about WTAC having almost zero on track but lots of pits entertainment too. The Pro class really needs some changes to the format to get more cars out on track each session.

[R31Nismoid]

Only 250k?

Cummmon.... 2 or was it 3 engines down before racing even started has gotta give you a nice starter

[zebra]

lol sif they would say what the real cost was
