FITT Miata Tuner Challenge

I have to say thank you to my friends in FITT for allowing me the honor of hosting this Miata tuner challenge. I spent an hour looking through six years of photos from racing in the SCCA Spec Miata series and a flood of really great memories came over me. I cannot wait for all of this snow to melt and for the 2014 racing season to start. I have two sets of new tires just waiting to be abused.

First, I had a mission in mind when I picked the cars and the four classes. Mazda has been very active in the United States at trying to develop a ladder system from beginner to pro for road racing. Most of the professional racing drivers in the U.S., well, at least the ones who can actually make a good living from it, all drive in circles. Yep, NASCAR, with a large audience made up of beer bellied hillbillies that drive large television ratings because, well, who watches a lot of TV.

Road racing fans who once called Speed Channel home on Sunday afternoons are now left to hunt the internet to find any legal or illegal stream of road racing, just to get our fix since Speed became the Ultimate Fighting Championship network. That was the day I cancelled cable, but I digress.

So, I built this tuning challenge to somewhat mirror the spirit of Mazda’s ladder program. Beginners start out in Spec Miata and work their way up through faster cars to finally reach the ranks of pro road racing. Tuners may pick any two of the four classes, but Spec Miata is reserved for beginners. FITT tuner challenge podium finishers from the past may only pick from the top three groups.

Spec Miata is designed to give the average Joe the opportunity to go road racing on a budget. It is possible to find a donor car (maybe dead in your work parking lot) and give it a second life as a race car. I like to think that my Miata is enjoying its second life way better than its first.

If you have even basic skills with wrenches, a Spec Miata can be built in one's home garage.

It is as much about family as it is about the racing.

The racing is real. With fields of 25, 35, 45 and even up to 80 cars, we line up, wheel to wheel, driver against driver and somehow, usually, all make it through turn one.

Road racing was a dream of mine since I was a small child. I have raced slot cars, BMX, go karts, remote controlled, video games, autocross and then finally, at the age of 35, I realized that childhood dream and went road racing.

It is a ton of work...

FITT Miata Tuner Challenge Wrap Up

I would have to say, mission accomplished. With this FITT tuner challenge, we set out to emulate racing with the Miata from the amateur level and up the ranks to pro racing. The Spec Miata class, open only to new tuners, finished with seven drivers all separated by only 0.7 seconds on average lap time. That is so close to the way it is in the real world. Compare that to the Roadster Touring Car group where we had one tuner find a trick that allowed for him to own the top spot on the podium by a full second. This is also very real world in the way one team finds something that provides an advantage until his competitors study it and quickly catch up.

Trust me when I tell you that I had as much fun as everyone who has posted comments in the thread. I am honored that so many tuners and testers entered this event. Sincere thanks from me to all of you.

And now, on to the final official results. Congratulations to all of the winners.

FITT Rules

General FITT rules: https://www.gtplanet.net/forum/thre...-tuners-and-test-drivers.291311/#post-9017285

Deadlines:
Tunes are due Sunday, March 2nd at midnight, wherever midnight is in your part of the planet. I tend to wake up around 6:30 am Eastern Standard Time so pretty much have your tune posted before I get to the computer on Monday morning.

Test driver results are due Sunday, March 16th at midnight, wherever midnight is in your part of the planet. Testing is to be done in time trial mode using ABS1 and grip reduction set to real. Please post your results and feedback within this forum.

Scoring:
Fastest lap calculations - A maximum of 10 points can be earned from lap times. The tune with the fastest average lap time across all testers will earn 10 points. All other tunes will earn their score based upon how close their average lap time is to the fastest tune. For example, if the fastest tune earned the average lap time of 1:21.688 and the 2nd fastest tune equates to 1:21.832, the 2nd place tune receives 9.982 points (1:21.688 converted to seconds is 81.688 divided by 1:21.832 converted to seconds is 81.832 *10 = 9.982). Another example, if the fastest tune earned the average lap time of 1:21.688 and the slowest tune equates to 1:27.271, the slowest tune receives 9.360 points (121.688 converted to seconds is 81.688 divided by 127.271 converted to seconds is 87.271 *10 = 9.360). This method of scoring rewards tunes for being very close to the front and will keep the lap time portion of the competition very close.

Driver's choice - Each tester will score each tune on the scale listed below. Driver's choice scores will then be averaged across all testers. The maximum number of DC points that can be earned is ten points. Please choose driver's choice on a scale of 0.0 to 10.0.

Driver's choice scale:
10.0 among the best tunes you have driven in GT6
7 to 9 a great tune that could be a little faster if...
4 to 6 a good tune that needs a few adjustments to become a contender
Under 4 a tune that needs work (please be specific with feedback with any tunes listed here)



Photo mode competition to be announced soon. All photos need to be sent to me either in-game or through GT Planet PM. I will post all photo entries into a voting poll thread and we will ask the full GT Planet community to pick their favorite. I recommend that we all vote on someone else's photo and not our own. Let's show appreciation to our fellow GT Planet friends by letting them know which we like best past our own.

Not sure if I'm eligible for the spec miata class or not?
Did you finish in the top 3 for any previous FITT shootout? If yes, get out, it's not for you! :P You came 2nd in that Monaco shootout with the Stratos though, right? If you did, then you're not eligible. :P

Edit: I'll sign up for Improved Touring and Street Touring, kthxbai.

Just checked through a lot of the results in the GT5 FITT Shootouts and I haven't had a podium finish. There's a couple 4ths and 5ths but that's the best I've had. The only event I couldn't find was the FF tuner challenge on Cape ring. I used the Eagle Talon and I remember that finishing quite well but not sure wheater podium or not :/

Anyway I will enter the spec miata class and street touring roadster groups then please unless anyone says otherwise.

Very much a beginner tuner but would love the opportunity to try out at the Spec Miata event if possible? It's all experience and any sort feedback can only help, can't it?

I'm just venturing into the tuning aspect and this event will be ideal for me to 'Have a go' and learn a few things.

@Motor City Hami those pics look epic - so jealous!

I'd like to enter to Street Touring Roadster and Touring Roadster Car class please, purely because they both have only one car to choose from and I'm lazy!

@DozUk - you'll learn tonnes, that's the best thing about these events :gtpflag:

I have a question:

If i tune my car using Skid Recovery Force and ABS, will the test driver use those aids, or will they change it to their liking?

Skid recovery force isn't allowed because it would give your setup an advantage over everyone else's.

Jack is correct. I have a few more things to post in the rules section. The standard for test driving with the FITT challenges is ABS1, all other aids off and grip reduction real. My experience with SRF is that the cars tend to have the same front/rear grip balance but it acts like driving on one or two levels of softer tire.

I actually like to tune on harder tires than listed in the competition then switch to the spec tire for fine tuning. This really helps to zero in on LSD settings.

I am retuning my spec miata replica for ABS 1, got a co driver helping me :P, the new spring rate, damper and ARB made it faster by almost a second, but the car is wilder to drive ( loose ) than the replica :( The retuned version able to easily post 39s 2nd sector ( flat out exiting fish bowl ) at Street of Willow ... but I like the feel of the replica :grumpy: At least both can lap below 1:30s.

This will be my tune, and I will update the tune soon after I can make up my mind :lol: I made the appearance similar to your 51 ' 94 car @Motor City Hami, hope it drives just as good :embarrassed:

Notes :
I built the spec Miata replica long ago, it's still work in progress with some settings/specs still need to be work on. This replica is fine tuned to fit the rules for tuning challenge.
The car uses Spec Miata suspension setup as close as possible to real life, the balance is good with stable rear end and pretty agile front. Care need to be taken when exiting corners, the rear can wiggle a bit, but it should pose no problem :)

I tested the car at Streets of Willow together with a friend, the car can do 1:27s lap with ease, a good run would see sub 40s 2nd sector ( at fish bowl ). Tune is sill not final :)

Awesome! It is a known fact in racing that obnoxiously bright green paint is worth at least 2 tenths of a second at most racing circuits. ;)

So are you building a replica to be close to the real life Spec Miata settings, to the stock Miata settings or simply using one of those as a starting point and building something custom? If you are building one to real life Spec Miata, I can help you out with the popular set up.

I have 2 setups, one with spec miata spring rate ( 700 lb/in / 325 lb/in or 12.5 kg/mm / 5.8 kg/mm ) and the other one with different spring rate, arb, and damper, both drives well, the spec miata spring rate setup is a bit slower, I used base setup from real life spec miata car.

Something like this :
Front Suspension:
Camber: max negative
Caster: max negative (top of shock tilted back towards firewall), or whatever setting will allow the most negative camber
Toe: zero toe, or 1/16th" to 1/8th" toe out
Sway bar: full soft setting
Rear Suspension:
Camber: 2.5 degrees negative
Toe: 1/16th toe in
Sway bar: full stiff or medium setting (dependant on track. Stiff for a looser car, medium for a tighter car. Loose is fast by the way)

Of course, the camber can't be adapted like that :) I use little camber front and back. I'll be happy if you can give me some infos on real life popular setup :)

I read that most SM uses higher rear rake, and about 4.75 inch ride height, with some camber, front from 2 to 4 and rear around 2 to 3. Zero toe or slight toe out front, and toe in rear. Some suggested soft roll bar front and very stiff rear :) These works quite well in GT6 so far, except the camber :(

I will post my final tune above in a few minutes :)

racing stripes improve drag coefficient by a huge amount as well, that paint job alone should ensure a sub 7 minute lap at the Nurburgring!
