[Quiinten]

I think when you tune the Ferrari 599 '06 it will be a great car i can send you one if you like ?

 

[Rotary Junkie]

This may sound silly but, wouldn't it be better if you tuned all your cars on racing soft's for better lap times? I am fairly new to tuning, correct me if I am wrong or a reason to why you use sports soft's, thanks..

Racing softs would make for better lap times, yes...

But if you notice, most of our vehicles are street cars. You can't run slicks on the street very well. Also of note is that they're much more difficult to bring to the limit of grip and much more sudden in the way they let go; the sports tires allow you to have a lot more fun with the car before it decides to kill you.

I tried teh Enzo and Gallardo last night. Mine were previously fully upgraded but the tunes still worked pretty well. I'm quite heavy handed with the accel and brake (l2&r2) so i turned Skid recovery on and i altered the brake balance and abs a bit til i got used to braking more carefully.
At first i was a little dissappointed with how the cars snaked all over place when braking from very high speeds (not the tune, just the cars themselves), I use the 'circuit de le sarthe 2009 (no chicanes)' track for my test track and it has a fantastic straight followed by a very nasty 90 degree right turn. one thing driving these cars has done is vastly improve my braking and i'm a lot less heavy handed with the braking and its helped improve lap times with my other cars.
I've never been a big fan of teh Enzo but after testing out the tune its deffinitly begun to win me over so cheers m'dears

The Enzo is lucky to not simply go straight under braking (and throttle, and when coasting) The Gallardo I'll admit to being more than slightly hairy on entry... But that's exactly what makes it anything resembling interesting to drive; if it was dead stable on entry you'd never experience the nutty 4WD powerslides that can go as long as you have power. Good to hear you like them both, better to hear they've helped your driving.

Heyy xx used this tune... awesome... i had absolutely no problems... it earned me 800k in one go xx thanks

OMFG... BEST TUNE EVER i won the seasonal by 1:22:00 xx awesome... prehaps a dodge viper ACR in the future?? xx

Thanks. As for the Viper... Well, maybe. I've got a tune for it but I still don't like the car itself much.

Here's a little review of your 300ZX:



There.
In all seriousness, what a brilliant car! It left me speechless. My first choice was to take it to the 'ring for testing because the numbers it put out seemed great for the Green Hell.

I realized what this car was as soon as I hit the first left-hander. Oversteer that can be so easily controlled and corrected, very precise turn-in even under braking, acceleration that simply fits whatever track it's put on, and abundant power throughout most of the RPM range. And this was on Sport Soft tires.

So then I took it the 24hour Nurburgring. The first corner really tests your timing and your car's braking ability since it's such a low speed corner after a long straight. The car feels sure footed and still handles pretty well under full braking. Also, as mentioned before, the oversteer on corner exit really makes this car so much more fun to drive.

My favorite feature on this car is how neutral it feels when cornering (under little acceleration of course), braking, accelerating, even drifting. Great all-around car. It already has abut 852km since I bought it just a couple days ago.

Hehehehehe. Someone's found the purpose for that Z. Mountains of torque at low revs means you can get it sideways easily enough yet still keep it in check with a bit of movement of your right foot (or right thumb/index finger, depending on control method).

I have just run the RX-7 for a dozen of laps. It's great. The car is very predictable and is pretty easy to handle. One thing I did not like was the front end understeering while coasting. I adjusted the Anti-roll bar up front to 5 instead of 7 and magic happened. The car is now very very well tuned. It totally suits my driving style and is a real blast to drive. You can basically grip it or drift it and it will go where you want to go.

Thx a lot, good work

The 7 will be undergoing a bit of surgery soon; I've made it far better online and cut most of the push out of it. Sad part? I know this won't be the final revision.

Since they added ballast to the latest version, I tried to play around with it on the Enzo which has such a light front end but I can't seem to improve the lack of grip in the front end. Any suggestions?

I may try messing with the ballast on it; it seems like the Enzo lacks front grip more than anything... So shifting weight further rearward may help it quite a bit; forward bias will likely just cause understeer.

Hey guys, ever thought of making a couple tunes without rear wings? I mean, they help, I know. But they look horrible. I'm highly reluctant to put big black rear wings on cars because they ruin the car. Some premiums have dedicated rear wings (like the 300ZX, R34, etc) that look modest but sporty, and those are nice.

Would it be too much without a wing? Just curious.

Best example is the C63. Such an amazingly beautiful car looks horrible with the wing.

Roj's own C63 actually runs without a wing; the one that got released was YassirNosir's which had the appearance-killing wing. There will be a few cars popping up soon that remain wingless though. 👍

 

[VTiRoj]

MX-5 SC gear ratios updated. You'll be able to squeeze a couple more laps out of it around Tsukuba now since second gear won't cause wheelspin as easily.

Edit: And the Civic Type R Turbo. Before, we used long gear ratios to supress the wheelspin but it resulted in a sluggish fifth and sixth gear. Now we've got a longer first, second and third, then fourth is relatively the same, but fifth and sixth are much shorter so the Civic will keep accelerating all the way to 180mph and beyond.

Edit 2: 787B gear ratios up. We've managed to improve it to the point where it only needs TCS: 1 if you're a lead-fingered DS3 driver and the top speed shot up to 245mph.

Edit 3: S15 Silvia Spec V updated. Gear ratios, suspension, LSD and brake balance tweaks.

Awesome, now my C63 can get some action apart from drifting.

If you post cars that can be used without wings, I'll be sure to test them.

 

[VicioustC]

This is a problem we faced when we tuned it and no matter what we did to the suspension, it wouldn't solve the problem. The best way was to change driving style when using the Enzo. As for ballast, we've not experimented with it on the Enzo. My only suggestion would be to add some weight behind the front wheels to try and bring the weight further forward.



Did you set the gearbox to default settings before trying?

Yes, I got the Civic Turbo's gear ratio settings to work but for the LFA I'm still coming up short for 1st and 2nd gear:
1st:-- 3.672
2nd:-- 2.458

However mine only goes down to 3.710 for 1st gear and 2.484 in 2nd with the max speed set at 230mph

 

[Rotary Junkie]

Do you have the correct parts installed? A higher stage engine tuning for example would raise the rev limiter and cause the gearing to be "too short" vs what's specified.

I've set my own LFA to default and adjusted it from scratch but I can still reach my claimed ratios. However you're not too far off anyway so it'll be good at the number's you've got it at. 👍

I remember this problem from GT4. It's probably what's happening now.

RKM Motorsport’s R34 Black Edition

what can I say....

I have been lucky enough through my job to have had 20 minutes behind the wheel of a real vSpec R34. Driving that car in real life was a high point in my automotive experiences. Once I got over the difficulty of shifting with my left hand, I experienced an automotive epiphany. Never in my life had I experienced a car that would do exactly what it was told.

This tune is the virtual equivalent of driving that R34. You point, it turns. You stomp, it goes. Out of the box this tune will do Tsukuba from a standing start in 1 minute. It doesn't push, it isn't overly tail happy. This tune will become my default car of choice in the 450 hp range. This tune has made me a believer in RKM's tuning abilities.

P.S. this tune was so good, it made me finally go from lurking, to posting on GTplanet!

 

[GT5_Honda_Guy]

Did you set the max speed to 230 MPH first before adjusting each ratio?

Yes, if I have too much HP, can that affect the gear ratios? Just noticed I have more HP than the tune calls for.

 

[ryangt]

Was wondering if there was someway you guys could mark on the first post which cars gears have been fixed?

 

[Paulie]

If they're going to do it anything like how I plan on doing it, then the tunes with updated gearing will also have power restrictor and ballast weight listed on the tune sheet.

 

[Rotary Junkie]

Pretty much.

Updated F430 Stradista's gearing. Z06 RM, Atenza 23RS next, along with updated suspension/gearing/diff/parts on the RX-7 R400.

Edit: Z06 RM done.

 

[VTiRoj]

Yes, if I have too much HP, can that affect the gear ratios? Just noticed I have more HP than the tune calls for.

Yeah it was a thing in GT4 too. Using higher engine or turbo stages would give you different ratios to that of a car with lower stages.

Yeah, all the tunes with power and ballast settings in their sheet have been updated. Those without have not. I'm updating in order so everything from the NSX-R 3rd Anniversary to the S15 Silvia Spec V has been updated. 👍

 

[fildunn]

only starting using your tunes a week or so ago and thought it about time i did a review, and because i have a tune request

The Ferrari Enzo GT

i have always been a fan of this car, and as soon as i had the credits i rushed to the ferrari dealership and handed over 1,000,000 credits. i popped on a set of slicks and headed to my favourit testing track, trial Mountain to see what time i could get............i was then introduced to the most incredible waste of 1,000,000 credits known to man. to say it was difficult to drive would be the biggest understatement. im not sure what's worse, the ridiculous turning circle, the light front end that causes unbeleivable amounts of understeer or the sudden bouts of fatal oversteer. either way just keeping it on the grey stuff is an acheivement, forget any kind of respectable lap time. The Enzo then sat in my garage gathering dust for almost 2 months until yesterday i decided to try RKM's tune.

so what is it like after RKM have tinkered and tweeked? well its still light at the front, still understeers and still oversteers.......but now its manageable, it requires skill but it is managable. they best way to describe how it behaves is to say this car is all about patience. The Enzo is always going to be a handfull but if you treat it right you will be rewarded. feather your braking, turn in, feather your acceleration and then when there ia a bit of straight tarmac, unleash the Enzo.....its all about the bits inbetween the corners, and it eats these up at a phenomonal rate the corners them selves are.....exciting. im now about to go and imporve my laptimes knowing it is possible.

in summary, supercars are supposd to exciting right? RKM i salute you. i like the fact the Enzo is a bit of a knife edge. after gathering dust in the corner of my garage of 300+, the Enzo has now entered my favourite list. a club of only 8

*proud Enzo owner*

Thanks for the review! The Enzo has a lot of problems that tuning cant help. The brakes, light front end and the lack of grip let this car down big time. That said we're happy we managed to make the Enzo manageable so people can enjoy driving it. You're right about how to drive it. It responds better to being treated with finesse. If you want to hoon in a Ferrari, you're better off with an F430.

Also, Yari Yari, Midnight Z and March Super Turbo have been updated.

Max speed for the F430 124mph?

 

[VTiRoj]

Transmission
Set Final 1, then Max Speed, then Final 2 + individual ratios.
1st:-- 4.139
2nd:-- 3.037
3rd:-- 2.367
4th:-- 1.931
5th:-- 1.603
6th:-- 1.390
Final: 4.300/2.500
Max Speed: 124 MPH

Max speed for the F430 124mph?

124mph is just the autoset. If you follow RJ's directions, you'll see the actual max speed (displayed beside the gear ratio graph) will be a lot higher than 124.

 

[Quiinten]

is the 908 killer whale any good for the 24h le mans ? or is that not the good set-up for that race?

Some say it’s possessed by a certain old Z and that all you can hear from it at night is the “whiiiiiiiii” sound from it’s supercharger, but all we know, is that it’s called the Midnight Z.

23rd Feb 2011 - Transmission & ballast/power settings.

I have been running with this tune for about three weeks now and all I can say is, WOW. This car is an absolute beast. It is great for someone to really hone their skills on AND can be built up. I'll explain....

I started out with this tune opting for the weight reduction, LSD and transmission due to budget (just starting out, you know?). IT was a terrific car. Handled like a dream and really helped me get the hang of it. It oversteered a little in the beginning but that was ok. It helped me really understand how critical it was to "set up" the car for the turn. In no time I was running perfect laps and blowing away the competition. Fast forward a couple of levels and the rest of the performance upgrades and there really is no comparison. It is now my go-to car for my Bob and most other A spec races. Handling is fluid and precise. It still has just a bit of oversteer but I am sure that is more due to my driving skill/impatience. The acceleration on this car is ridiculous. Pay attention because you can easily hit 100+ on a very short straight.

The braking on this car is perfect. I can jam down on the brakes at speed and never worry about the rear end stepping out. The brilliance of the boys at RKM really shows off in the LSD tuning. Braking and Acceleration are exactly what you want.

Overall, this car is an excellent build and has really paid off in terms of income and levels. It easily has paid for itself 3X over. I recently ran the FR seasonal event and it really wasn't even fair. If you want a cost effective tune that will get you through the mundane beginning races for A spec and B-Spec, yet still give most cars in the online lobby a run for their money, then look no further than the Midnight Z...

 

[VTiRoj]

Yeah. The F430's peak power isn't stupidly early like the C30 and Impreza.

It'll kill the competition at Le Mans. You don't even need to push it that hard, just take care of the tyres. 👍

Three weeks? So that's where the car was all this time. That bit of oversteer is the supercharger making friends with you. The Midnight Z is just a car for pure driving enjoyment, the fact it's also a sweet track car is just a bonus. :tup:

Glad you liked it! The building it up in stages is a nice thing to hear. It's always good to know that a tune can be built on a budget and not lose much of it's performance. It saves you money too. If it wasn't for the seasonals, my Z would still be in debt to me now.

Hey guys,

I've been trying your tunes recently, and I have to say, I'm amazed. Ye're tunes have been working out great for me recently. I even bought cars just to try your tunes. I really appreciate all the work you put into your tuning 👍

Anyway, I'm here to review one of your tunes:

RKM Motorsport’s Blackpool Tuscan

I had this car for a good while and I seen this tune, so I decided to try it out.

I'll describe how driving the car was.

It was amazing.

The car just stuck onto the road like it was on traintracks. Even when the tyres began to wear, the car stayed on the road. I tested the tune on Special Stage Route 7 on a One Make Race, and the tuned car owned the competition every time.

On my first try, I decided, because I had put on Engine Stage 3 onto the car before I found out about the tune, and your tune didn't require any engine upgrades, I would set the Power Limiter to 456HP. The lap went brilliantly, but i noticed some slight understeer. This wasn't much harm though.

On my second try, I decided to restore the Power Limiter to 100%, and the understeer seemed to disappear. The power increase also reduced my lap time by over 2 seconds.

This car was my first Racing Modified car, and recently it has been ignored in the garage. You guys put this car towards the centre of attention in my garage, and that is something I am very appreciative of.

Overall, I believe this is one of your best tunes. I hope your tunes in the future will be as good as they always were.

Best of luck,

Dean

The Tuscan is a car that amazed even me. After knowing how lethal TVR's were, it was a suprise to find this Tuscan didn't want to kill me after 5 seconds. The Tuscan isn't fully tuned and is infact missing a few parts, at some point I'll probably update it. It was a request tune so it's using the parts the requester used on his Tuscan. Thanks for the review! Much appreciated.

I knew this day was coming. *sigh* I suppose I will since you did fulfill the requirements for a request car, and I suppose it'll be blazingly fast, but know I will find no joy in the job of making it decent.
