RE: 360 Tuning - cologne - 01-26-2008

This is a first tuning of the 360 with the real power (~400HP, torque-curve interpolated by hand) and speed (300Km/h) and now it´s Rearwheel driven! ;-)

...,only a first step.

I have checked in your changes along with some of my own. I found a torque curve from a dyno graph here: http://www.dragtimes.com/Ferrari-360-Timeslip-8801.html

Also I changed the gear ratios to match these: http://www.supercarsite.net/ferrari/360-modena/2000

I also updated the hood camera position so that it is correct. This is all in the data repository r142.


- joevenzon - 01-28-2008

Uhm... are you sure you got the units correct on the torque curve? The car seems a little... slow.

It´s from an roller dynamometer, gives power an the tyre! With a drag of 0.30 nearly 270 Km/H. ;-(

The motor was in the Front and some other bad things... I am working on it.

Braking makes the car instable.... but it´s getting better!

joevenzon Wrote:Uhm... are you sure you got the units correct on the torque curve? The car seems a little... slow.
Yep, I used Google calculator the same as I always do to convert torque (in ft-lbs) from the dyno graph I linked above to Newton-meters. But cologne raises a good point, rolling dynos don't report the torque at the flywheel which is what VDrift/Vamos uses (afaik anyway). I'm not sure the best way for us to adjust for this, so I'm not sure we should. But that could explain why the car feels a little slow, other reasons could include bad weight distribution, etc.

Actually, I think it's not all that slow anyway, even for the current weight (which might be close, the 360 is supposed to weigh around 3k lbs). The car certainly has traction problems through first and second gear, and with the new transmission setup, the trip from 3rd to 6th is pretty fast.


- joevenzon - 01-29-2008

In data R147 I made some changes to the 360:
* wikipedia says the max torque is 373 Nm, so I scaled the dyno-based torque curve up to meet the spec value
* I played around with the clutch values so the starts work better
* I played around with the racer pacejka editor and created some new tire coefficients (pretty much from scratch)
* I modified the engine inertia to make it rev a little more slowly
* I tweaked the brake bias a little bit to try to get better stopping, but wasn't very successful

Changes are highlighted:

Update - cologne - 01-29-2008

Better a new Topic: „360-Tuning“ !?

--------------------
I work an mass distribution, suspension and some other parameters 3h this night. But three testdriver at the same time....!

Quote:* I played around with the racer pacejka editor and created some new tire coefficients (pretty much from scratch)
? Where is this editor?
Quote:* wikipedia says the max torque is 373 Nm, so I scaled the dyno-based torque curve up to meet the spec value
P 232.059 KW = 315 HP exactly
To scale gives a realistic curve.

Quote:* I modified the engine inertia to make it rev a little more slowly
False. This lowers the car control. Most of the inertias are too high!

Quote:* I tweaked the brake bias a little bit to try to get better stopping, but wasn't very successful
I computed the mass distribution with new masses and changed the brake bias.
The car is very instable breaking (with ABS!) ?-)


Here is my latest configuration. (Update 20080129)

We should set you up with SVN access to the data repository. I've committed the above to data R148.

I'll move the tuning parts of this thread to a new one.

No kidding, ABS makes the braking horrible!

Quote:No kidding, ABS makes the braking horrible!

It doesn´t brake with ABS, or the rear breaks out!

I´m trying different parameters, without success. :-(

Lowered brakeperformance, bias, inertia, but none shows a usable effect.

Changed the damper and spring rates. So the 360 moves good and goes better through curves.


@joevenzon i send you a request for SVN Data!

What's your sourceforge member name?

The 360 is now breakable and stable!!!
(Update: 7:49 Nuerburgring, first flying lap)

The suspension::hinge made the problem: greater than Wheel position (X) the car turns around on braking.

Not the last word, but driveable (version v. 360-05):
( tyre diameter corrected )

Sorry! :-(

Quote:Update: Didn´t know what happens, but with rapidSVN the file is commited! I hope nothing ist destroyed! ;-)

Actual Version 05: with blender-file, Ferrari-data and -pictures corrected mass distribution and dimensions.

Seems to be a little too fast: Nuerburgring about 7:40; i found a 8:04 for 360 Modena. May be the tyres are slicks... :-)
Easy to drive.
ABS can kill the engine!?
