GT4 Tuning - An interesting little test - Volunteers needed

[Sphinx]

Sphinx, that issue is actually a moot point, as the only perosn your really racing, is your self. We're not comparing lap times, but rather your evaluation of a set-up. The lap times are an assist in your comparison of the two set-ups. There need be no discussion of lap times, only differences in lap times.

Hi Der Alta, may I draw your attention to a snippet from Scaff’s initial post:

and see which one results in the better lap time and the better car to drive.

Perhaps I misunderstood what Scaff was saying, but to me it read as; let’s see which setup produces the better lap time and also which setup is the better car to drive.
I apologise if this is incorrect. However, regardless if I was incorrect or not, I can’t see how it is a ‘moot’ point because the differences between NTSC and PAL have been well documented, the Dodge Viper GTS-R Team Oreca '00 for example. In this case however, I admit that the differences with the Caterham Seven Fire Blade are only slight in terms of handling performance, but when attempting to drive to the max, it is noticeable.

In any case, I only mentioned it so you guys were aware of it beforehand. I won’t make a meal out of it by raising it again unless asked. 👍

As for track, I do agree that Midfield is a simpler track, with less to take into account. This would assist us in our evaluation, as a complex track gives rise to considerably more variables that can be accounted for. In a scientific experiment, the less variables, the better as it makes for a cleaner hypothesis at the end.

In this regard, I'd like to use Midfield as it a very well known track, it is simple, and it would best fit our evaluation.

Amen to that. 👍 👍

Can you add Ron (MrP) to the list? Ron would be a great asset to this, because he has what it takes when attempting to get the best out of a GT car and his input would be invaluable. 👍

That's not going to help. The setup you receive will only be designed for 1 track.

I know, I know.

I was only being facetious...

This is the way I understood it too - compare the difference in laptimes between the two setups. However, not between drivers...

 

[errk]

Count me in. I like the Caterham.

 

[Der Alta]

Wow, two apologies in one day.

My fault guys, I did miss that portion of his initial post. Although.... Technically we're both right, as the difference in lap times is what you get when comparing two lap times. And we won't be comapring lap times between racers, only against our selves. So, in that regard, the PAL/NTSc difference aren't applicable.

All that aside, they've clarified their intentions and I'm in the midst of penning the PM. Yes, P will be included in the group.

Looking forward to this. The only grumpy part on my portion, is I'm racing for the next two nights in the garage, with no heat. Wife has comandeered the TV in the living room.

errk, you should have the PM as well.

 

[VTRacing]

pm received, though a bit late for me.

Now it's time for me to sleep.

A note to both tuners: Caterhams with a Supercharger kit nets you 290HP if you add a Semi-race exhaust rather than the Race exhast. That's 50-60HP more... Are the setups supposed to handle the difference?

 

[Sphinx]

yep, got the setup PM 👍

Just out of interest before I start on this later tonight, has there been anything in terms of settings/tuning that have been ruled out?

 

[Der Alta]

NO, from my understanding, the two tuners discussed the power options, agreed to those and allowed everything else to be adjusted/chosen. Hence you'll have to buy two caterham's.

 

[Metar]

Ok, got the setup, and I've already got 3 Fully-tuned 'Hams. Now I need a new one without a rollcage.


Also: Next time, tuners, try not to tune so characteristically. It's pretty obvious who's who...

 

[TheCracker]

I'm glad you've gone for Midfield. As a veteran of 3 UKGTP's, i've found that Midfield is one of those tracks where driver skill plays a much smaller part than consistancy does. You can beat A.I. cars on any track. Gaining time on a human opponant is much harder. This is why Midfield is a universal favourite for set-up testing. 👍

When the results are published by Scaff/Der Alta - it would be nice if we get a 'theory behind my set-up' from each of the two setter-uppers (suchayo & Scaff) just so we can see why certain changes are made.

I've just noticed that Set-up 1 includes a rollcage whist Set-up A doesn't - a rollcage is a none returnable item isn't it? - Once you've bought one and fitted it, doesn't it stay? I guess '1' should be done before 'A' in that case (if the same car is to be used)

Exactly. That's what I did in the Week 14 Tuning-Comp - went by "No oil, no rollcage" first, then gradually applied those mods, too.

OK: Orange Caterham is the A-Ham, Silver is 1. Turns out both had no Chassis-stuff, so they're ok.

What I lack in GT4 skills (WRS Div 3 Podium Sniffer), I might be able to make up for in set-up evaluation/write-up skills, as I'm a Development Engineer for Bilstein.

We'd love your input in any way - more engineers in this discussion is precisely what we need. Scaff has done a great job holding up the technical end of it, but a few more educated analyses would really help.

I'm in, though I guarantee I will not be able to run or submit before Christmas. However, hopefully I can submit some late-entry feedback. I've gotten the setups from DA and I'll stay away from the discussion until I get to run, so I don't get any clues as to which is which.

Is set-up A supposed to just have normal brakes? Its losing out big style in the braking areas.

<--- Hammy is testing set-up 1 at the minute.

And a regular Flywheel, too!

1-Ham does fine right now, but I can't get a satisfying lap...

Indeed it does have normal brakes.

Should it suppose to have Racing brakes, could the tuner please drop a PM to attest to that.

Thanks.

 

[Sharky.]

I'll do this.

Maybe it'll help me improve my utterly rubbish GT4 tuning skills

PM sent.

Remember, the evaluation is of the settings, not what you'd change, or modify.

Good Luck.

 

[Sharky.]

👍 Drive, evaluate, post opinion.

(with the tuning skills bit I meant analysing the differences between both setups and their effects would help my tuning "skills")

Did I miss something here? The information I received on the two Set-Ups result in the same amount of power: 239HP.

Here's my understanding of the only major differences:
1. Set-Up A does not get a stiffened roll cage. (Which is somewhat of a hassle, since I didn't really need one of these cars let alone two. )
2. Set-Up A uses Normal Brakes & a Standard Flywheel.
3. Set-Up 1 uses the default Final Gearing, since nothing else was specified (Besides the Auto Setting # of course.).
4. Set-Up 1 didn't specify Driving Aids settings, so I'm assuming we are to use 0/0/0 for the sake of comparison.

I was waiting for someone to make that comment, might as well have been you.

That is correct. Both participants have verified that the PM layout is correct.

 

[AngelCreator]

I got the PM. And maybe this will help me to learn how to tune better from looking at the setup's.

 

[Sphinx]

If Set-Up 1 didn't specify any Driving Aids adjustment, then surely that means that they should be kept at default?

 

[Der Alta]

The tuner posted his clarification, it was by his mistake, as he assumed that we'd all drive with ASM & TCS = 0.

Neither set-up runs with ASM or TCS turned on.

 

[AngelCreator]

Neither set-up runs with ASM or TCS turned on.

That's a good thing to know.

 

[Sphinx]

Cheers Der Alta.

 

[Sphinx]

Turn 3 is fun
I'm off to bed now. I've done a few lap with just one setup and it looks like a sub 1'20.00 is a good target to aim for.

 

[east]

Just something I noticed (sorry if everyone already new this, I didnt) I dont know if this happens on every car or if its just on this car, but if you give this car all the power mods including the supercharger but excluding the Racing Chip, the car gets 268BHP, then when you add the racing chip it reduces the cars power down to 228BHP.

 

[Blake]

Well after only a few laps I already have a very definate set of views on each setup&#8230;
