ZR1 - Like The Wind - Indy - Tunes, Tested & Timed!

Now that my ZR1 is fully broken in, I thought it'd be nice to fairly compare all the current tunes. The #1 race use for this car appears to be 'Like The Wind' in Extreme A-Spec, where people try to make the quickest cash they can! So for this test, I ensured my HP was at 905 for every race. Every upgrade possible, with the exception of Chassis Rigidity, on Racing Soft Tires. Only laps 3, 4 and 5 are included, to ensure that no draft was present when comparing times. All tunes where driven on the same line, within human error, and done so at full throttle, with absolutely no letting off, or trail braking. No practice was done before hand, with the exception of previous grinding. Each car got a cold 5 laps, no exceptions. Best out of 3 for ranking.

The glaring defect with this tune falls directly on it's lack of rear downforce. When exiting corners you can feel the rear end sway and at times snap when it catches straight line stability. Definately not beginner friendly, I do not reccomend this tune to people looking for comfort, or a smooth ride. But it still managed to break the 42 second barrier. I'd also reccomend a slightly higher top speed.

RKM Motors: 41.794 : https://www.gtplanet.net/forum/showthread.php?t=136731&page=4#post4259821
This set up is not specifically designed for this track, nor is it for this car. It was actually based on the Z06, but due to RKM's popularity, I felt it deserved to be included. Good thing too, because it ripped off a .7! Unfortunately I feel that this tune is the least forgiving of all tunes tested. Zero room for error. Period. If you don't enter turn 1 at the exact spot, you're in the wall, no questions. Granted, IF you enter at the correct spot, you can expect to see some .7's, but this was the least consistent of my tests as well. Still impressive for a 'general' tune VS the competitors 'tailored' tunes, even moreso when considering it was based off of a different car and different tires.

Jorday: 41.698 : https://www.gtplanet.net/forum/showthread.php?t=145198
This tune might night have made the fastest lap, but it's the one I reccomend for the majority of people to use. It's very forgiving, allows you to use multiple entries without risking a brush with the wall. The most versatile and nimble I've tested thus far. And still ran a .6, very impressive. There are a few things I dislike though. From the center out, the car exhibits a small twisting motion, from left to right. It's subtle, but annoying and is probably the cause of my second complaint, which is that this 'twist' can cause a tug on the wheel on corner exit. It's just not as smooth off the corner as I would like. But, on the other hand, it wasn't designed for me, but just like to give feedback. This tune best suits the DS3 players in my opinion.

Avid Racing Factory: 41.695 : https://www.gtplanet.net/forum/showthread.php?t=147415
This review will be identical to RKM's. Not designed for this track, zero room for error, but still manages to make it around the track with a very impressive time if done correctly. I don't know what 360KM converts to, so I just used 261, because it looks kinda close digit wise.

Default: 41.648 :
This is an uncommon occurance, but one that stood out. I always like to drive the car before I play with the settings or test someone else's tune, simply to get a grasp of what they changed, and how the car responded. In this case, the default settings gave me an amazing Lap Time. LSD and all suspension settings are 100% default. I didn't touch them. The only changes I made, were Tranny Top Speed to 255 and Downforce to 35 / 53. While this tune is very stable and smooth, it has room for error, but not much. It's not out of control, but if you enter the corner incorrectly, you will end up scraping the wall. I do want to give credit to Jorday, as I stole his Downforce settings. >8) While this set up is slightly faster, I still reccomend Jordays tune overall for forgiveness, room for mistakes and agility, which does come in handy to get to an early lead, working through traffic.

Sail IC: 41.557 : https://www.gtplanet.net/forum/showthread.php?t=135770
Wow... Personal Record for me. I initially expected this to be another RKM outcome. Not designed for this track, a general purpose tune, for a different series and yet a jaw dropping .557. Which I must say, did not happen by chance, seeing as how it also ran .720, .635 & .606 in the same 5 lap run. Not only was it faster, but it also had more room for mistakes than the other tunes, with the exception of Jorday's. For advanced drivers I would have to recommended this tune hands down. If you don't need the room for error, then save a tenth with this tune. If you want a forgiving ride, then stick with Jorday's.

Honorable mention goes to Markyboybatey: https://www.gtplanet.net/forum/showthread.php?t=142858
To be honest, this tune is just the default settings with a very minor tweak to shocks and sways. So I don't think you deserve much credit, but using your sways, I still managed a .6, so I wanted to toss your name/thread in as well. 👍

I want to thank all tuners for sharing their tunes and allowing people like me, who suck at tuning, to still have fast cars to run with. I think it's great that you guys not only allow other people to steal your hard work, but you actually enjoy it and continue to do it! I'd also like to apologize to anyone who I may have missed. I haven't been around but a few days, so if anyone has a link to a tune they want me to add in, I'm more than willing to do so. I look forward to future cars/tunes/tracks to try my hand at.
Thanks,
Adrenaline

Thanks! 👍
Could you sketch your line on the track haha.
Im managing low 43's but thats without the max 905hp yet. (erm driven in or w/e)

Cool test and especially the commetry. Very nice write up.

Of course I feel good coming up on top. I don't view myself as such a great driver, so maybe I should use Jorday's and go faster .

My ZR-1 maxed out at 849Bhp, doing times of 42.3s at indy. Where did you get that extra 56Bhp?. I max tuned the car and then later i bought the race mod.

nice job man. i definitely can't even come close to duplicating those results with the default settings. when i use the default settings, the race starts, i make the first turn, and then i smack the wall in turn 2. with my tune, i did run a 41.4 one time i think.

are you using a wheel or a DS3?

these results are so much different, that the only thing i can think of is there is something different..maybe not necessarily in the settings...but somewhere somehow there has to be an explanation for this...that we are failing to consider. for you, the lap times for the last four tunes tested are essentially the same. this is confusing to me because if you take a car like the formula gran turismo, a car that no matter what you do the settings can drive around this track very easily. however even though the fgt can make all the turns in its sleep, playing with the settings still change the lap times a little bit. it just seems strange that you can use vastly different settings and run the same lap times with all of them. seems like even if you could make all the turns, the difference in suspension settings would at least cause slightly different amounts of speed to be lost in the turns and thus changing the lap times would at least be a tiny bit different

i haven't been able to watch your video because i cant get on my email for some reason.


one nice thing about my tune and sail's tune, is that you can use them for regular circuit racing. you can win gran turismo all stars no problem with his tune i've done it several times. depending on driving skill and personal preferences, my tune could maybe reduce your lap times if you find that you are able to control the car without difficulty.

Great thread, Adrenaline!

I have been trying to make sense of the ZR1 RM tunes myself. This is exactly what I would have liked to do if I had more time. Bravo!

I feel like we are finally getting to the bottom of this.

I'll have a video on youtube by tonight. It's nothing impressive I promise, lol. The video will only be of the default settings, running a .7 though. I did save the replay of my .5 just in case though .

As the engine breaks in, the HP will slowly increase to about 895HP where it peaks. When you get to this point, change the oil and it will put you at 905HP.

Uploading to youtube as we speak, but I use my 3G Cell Phone for internet so it'll be about another hour or 2 to finish uploading. I tried to send via email, but the file was too large.

I use a wheel & pedals, and built myself a cheap version of those racing chairs you see for like $800-$1300, out of some 2x4's I had laying around, threw in my old racing seat and it makes the game more fun for me. The wheel is a Logitech Driving Force GT, nothing too fancy or expensive.

im wondering if it's the wheel that is making the difference. i guess you could try it with a controller and see. if that doesn't solve our mystery then im about out of ideas lol.

it appears that the game is really meant to be used with a wheel, as i've noticed when playing at my friend's house, who has a wheel and pedals, that the cars just seem to be able to do things they just wont do when using a ds3.

i had an extremely hard time with the x1 challenges using my ds3. i played at my buddys house, first time ever playing with a wheel so it took some getting used to, and i beat the challenge within about 1/2 hour. he has the exact same wheel and pedals as you have...and i was driving sitting on the couch with the wheel on the coffee table, less than ideal, and it was still easier than a ds3.

Nope the engine definitely isnt braking in, its done over 3000 miles and its always been at 849bhp with new oil

You have to RM the car before you start adding anything else.

*edit* using a brand new car.

Let me clarify, i bought the car and upgraded everything with the engine at 880Bhp and then took it to a race, it got slaughtered. So i had a fiddle and realised you could race mod it, i did that and then went and re-applied all of the previous mods which took me up to a certain number, the engine then broke in and worked its way up to 849bhp. I only did about 2 laps at Indy with the car before buying the race mod. Since that the car has done over 3000miles as i have used it for a few events and b-spec bob has raced it a lot.

It shouldnt really make any difference whether you race mod it before or after upgrading the car surely. The car had more power before it was race modded, than it did after the race mod.

I bought a new car, bought everything you could buy for it EXCEPT the race mod. it was 905 hp. I drove it a lot then i did the race mod. I had to buy most of the hp mods again, but still ended up at 905 hp.

Thanks for reviewing our tunes on the Indytrack. Sail deserves full credit for this because his tune was exorbitantly good to begin with!

Anyhow, I'm glad Avid's tune isn't too far off despite our factory being relatively new.

I think its best for more testers to post their lap times so different garages/factories can compare on a standardized platform.

Cheers

I'm matching these lap times with the Z06 Race Modded, not the ZR1, which people have said has more downforce, and is more powerful. Right now my Z06 race mod is around 865hp at 1100kg. The key here is to have the front downforce all the way up, that will allow you to take the corners almost flat out. The only thing is you have to let up on turns not brake. I can do 41 flats without drafting.

Video or it didn't happen.

j/k man, sounds like you have a good setup for the Z.

I don't have a video camera or recorder, but I guess I could use my g/f's cell phone to take pictures of the lap times, I'll have to do the race again though! So I will do it and then see if I can upload the picture somehow. Not sure where to host it though!

I haven't driven the ZR-1 much since I posted the tune Nov'30. I also don't drive much on ovals which probably needs a bit of a different tune to be optimized on such track.

Anyhow, I think where my tune work well is especially when breaking into a corner and on acceleration out of it. Where there is room for improvement is to get good turn-in into a corner when not using the breaks. This must be very important on an oval but is difficult to achieve (at least for me) in the tune.

So I don't think there is a miracle improvement for coasting turn-in. I would probably focus on the front toe/camber. The front camber looks a bit high for such a stiff front. It would have to be some trial-and-error, but I would start by reducing front camber and put in some front negtive toe and see what happen.

I 41:729

My tune:
Downforce: 35/31
Transm.: 410 km/h
Spring: 12.5/12.0
Camber: 2/1.5
Brakes: 5/5
others is default!

Nice write-up, Adrenaline! I hope you will review and compare tunes for some other cars, too. With so many Tunes to choose from, we could use a lot more comparisons and reviews like this.
