Didn't see any EZT team members on the sign ups...so I thought I'd post this for information.

The Virtual Motorsports Time Attack League Unofficial Series 2 takes place on Sundays at 14:00 CST / 20:00 GMT / 06:00 AEST where all competitors are split into divisions based on their qualifying times and compete against each other through a hot lap challenge to achieve the most amount of points possible! Qualifying takes place Sunday 6th November and the first session the following Sunday, with signups never closing. If you want to get involved or learn more, follow this link to the Virtual Motorsports Time Attack League Unofficial Series 2 section!

Thanks i will check it out

Qualifying was yesterday (I managed to NOT finish last).

CQR members had some really scary times. They will clearly be the guys to beat.

If anyone is interested, I've created a pretty good (at least I think it is) tune for the 2011 Citroën DS3 (car for weeks 1-3).

Let me know and I'll gift it to ya.

I would definitely appreciate feedback on the tune.

Thanks!

I ran the car a few laps yesterday, but used my own tune to get a 1:41.970.
I ran your tune, shotgun, and got a 1:43.9??.

There's not much you can tune on the Citroen as it is almost like running a stock tune.

I put the car's info into the new Forza 4 Basic Calculator to get my adjustments.

Hey Tom,

When I put the car's numbers in the FM4 version of Slave Monkey's calculator/spreadsheet, I came up with slightly different numbers.

Forza Motorsport - Summary
2011 Citroën DS3
Tire Pressure:
Front: 28.5
Rear: 28.5

Gearing:
Final Drive: 4.42
1st: 2.89

Here's my data entry:

Class B442
Engine Position Front
Drive Type FWD
Power 165hp
Torque 190.0lb-ft
Curb Weight 2,103 lbs
Front Weight 56%
Displacement 1.6L
Power RPM 6,000RPM
Torque RPM 1,400RPM
Redline RPM 6,200RPM

Front Tires
Tire Width 225mm
Aspect Ratio 40%
Rim Size 17in

Rear Tires
Tire Width 225mm
Aspect Ratio 40%
Rim Size 17in

Lateral G's 0.983

Transmission
Top Speed 139.7mph

So what part of the data entry did I screw up?

the only thing that I had different was the Weight Front %

I had 55% instead of 56%, but that didn't make too much difference.

Did you change any of the Strength %'s in the Advanced Section on the right?

Here's my corrected Summary.

Hmmmm...this is interesting.

The summary I posted was without the changes to the ARB strength and bias.

I can't figure out why we're getting different ARB, braking, and differential numbers with the exact same data input.

Are you using Excel 2007?
