Matra performance questions (test version available)

[edwin]

Finally, the test version is done.
Hopefully there are no big errors anymore, but you have to excuse me if so; I can't (and thus haven't) driven it for to long.

Changelog:
- added flex chassis
- HDV changes to go with the flex chassis
- made new contact patch tires (only! for dry tires for now)
- changed the character of the engine; power or torque are not changed by more than 1%, but the back torque, fuel pickup, throttle response have been changed significantly; the engine should feel more alive/responsive.

A little story; I tried to keep the grip degradation of these tires about the same as the old ones, but with the "benefits" of the newer.
As they degrade, the balance of the car shifts more or less back and forth. (Of course depending on driving style and degradation to go with it)
Steering with the back end (as was more possible with the EVE) is now more possible with the Matra too, but due to balance shifting from tire degradation; not always in the same way. The more responsive engine, should "help" you.

Still, as Klaas wanted, the Matra picks up just a bit slower than the EVE and has more rpm. Now, because of the changes to the engine, it has a bit more topspeed to compensate the slower acceleration.
I hope its okay, because I was not able to test that one fully.

To install; please remove the 1.0 version of the EVE_MATRA_F1. This was a Multi rfcmp and thus you have to go down all the way in the installer screen.
This version is a normal rfcmp and will be visible under "vehicles" and act the same as the original version. You won't see the sound package installed for instance, but its there, no problem.
It is called: "EVE_MATRA_F1_V1.1".

So, if "you guys" would help me out here, please test it and let me know what you think. I'm under no illusion its perfect yet, so don't spare me; you won't hear me cry as I'm to far away

One other thing; its not on the ISI forums yet. I want to do that when its finished; please keep it that way

Thanks for testing in advance!

And of course the link: http://www.mediafire.com/download/itm6ur...V1.1.rfcmp

Great.....just back home from work, but downloading now and will give it a shake down tomorrow. Thanks Navigator for all your efforts, really appreciated 8)

Well.....its a hobby Keeps me off the streets

So if you are willing to test; please, yes, that would be great!
Don't hesitate to give feedback that might be negative as it might not be that great.....just tested a few laps at Limerock with the full wing car.

[edwin]

i won't spare you....be sure off that :o
just joking, sure i will report back but give me a little time cause real live is taking all of my time these days

[Navigator]

real live is taking all of my time these days

A wise man once said: "real life is overrated".........hmm, who was that?? Anyone?

Hehe, take your time Edwin; no hurry! (I got the game for lifetime I just saw, so, before I die should be okay )
Thanks mate!

Thanks mate!

hehe.....so worked out well our little plan, good to hear.

hey wim..
I did a test at brizanna, running the matra against the eve. with wings, front and rear. I used the exact same setups in each. I did 10 laps each, got the eve better by .3 tenths of a second.
driving impressions - the eve seems to be lighter and more agile. the matra front end didn't stick as well and power band was slower - more grunt though. I had to gear down to a lower gear in the turns too. if I would have changed the setups to suit the matra a bit I could have done better with it.
then there is the sound - which is freaking AWESOME! If, I had to choose what car I would want between the eve and matra - it would be the Matra!
will test more during the week as time allows - next test will be to change the setup..
a suggestion to paul, could we have the Matra on at Brizanna short course - with both matra and eve F1 on server 2. that way all of us could shoot over and test and post what they think here..
Good Work Wim!

[Navigator]

Very well Edwin, nice

Thanks for testing Jerry.
What do you mean by "grunt"?

It was meant for the Matra to be a bit more "heavy"; Klaas wanted that because he wanted difference.
The point is, that it should compare with the EVE and so; with different feeling, it should have "other benefits".
As I read it; making the front a bit more stick, it could come closer to the EVE?
Maybe even a bit more power at low rpm? Can't go very much because it would end up just being an EVE

Hehe, sound is great hey? I didn't make it; its from another mod Klaas asked permission for, but the guy who made it should get a Nobel price

[jerry 33]

I did not mean to say I didn't like it or that it should be changed - just stating differences. grunt is torque. as I stated, with setup changes I believe I can match eve. I need to test more and get my wheel settings back over to F1 from lola. been a while since I lapped the F1

I do believe cars should be different as it was with GPL...

[Navigator]

Jerry, I didn't take it as if you didn't like it, no problem there mate.
But if -with default setup- one car is faster, it should be changed; goal is to match the EVE so it can compete.

You can make setup changes and get it 0.3 faster, but you could do that with the EVE too.

So if you say the EVE sticks more; that would be a nice point to improve on the Matra because it is already slower out of corners; that is to much difference than.

[jerry 33]

I have been using my setup for the eve that I ran at Brizanna - I will keep it the same then. I will also try the default setup.
if that is our parameters then: the front end seems to push on the matra going into all turns compared to the eve. will try to get a couple of laps in latter for a double check, family is coming tonight so we shall see......
still thinking over having both cars equal - if they are different, wouldn't they need different setups to extract their max performance? as long as the max performance from adjusted setups were the close to the same. also, one car might suit one track better.. i'll think on it, test and post

[Navigator]

You are right Jerry, but then you have to find the best setups for both cars......and that's a lot of work; I can't ask for that.
Also; as you say, they will be different on each track. I can't help that; we didn't want just a copy of the EVE.

I just want it as close as it can be, without feeling the same.
There will be a time difference depending on the track; so be it, but those should not be seconds.
I can imagine the Matra being slower at Monaco and faster at Monza; if we're talking about 0,2 or 0,3 seconds top; that would be okay I think?

So you say the Matra pushes; you mean it doesn't steer to well/sharp, right? Understeer, needs a bit more grip at the front as I understood in your former post too?
Don't want to do that with the tires because that feels like cheating; have to alter the geometrie.

[jerry 33]

hold off on changing anything just yet..
as I stated yesterday - I tested the eve vrs. matra with an old eve setup that I had. today, I used the default setup with 2 expections. fuel and gearing, I use 7.9 gals so I could go 10 laps. the gearing wasn't tall enough for Monza. I used default setup with same changes for both tests..
todays test showed the matra quicker by .239 and it was easier to grip with that default setup. I still downshifted a couple of place that I would carry a higher gear with the eve. but the eve would start pushing out. again, different setups seem to have vice versa effects due to the needs of the car. I was again using both front and rear wings. eve top MPH was 189 - matra 192
I think you would have to put both cars on server with matched fixed setups and have everybody have a go at it - but for me, they are close wim - well done!
hope this helps...

[Navigator]

It sure helps Jerry, very nice, thank you.

And a .239 difference; hmm, not bad I think.

Setups do differ; be it alone from the tire wear......the Matra with cpm can heat up in some cases and loses a bit at the front, than rear loses a bit grip and the balance is back. (Tested on a short circuit, lots of steering) One moment its better, the other its less and you have to use the rear more for steering. That also depends on driving style; some steer nice, clean, some -like myself- make a left turn while steering 70% of the time to the right
So one driver may benefit from the Matra, the other from the EVE.

But this difference you say, is very nice; I'll go for that!

Feel free to give some more feedback guys; the more, the better!

Seen it downloaded at least 9 times, so.......
