Need help with power-on oversteer and Camaro ZL1

You’re not suppose to use rewind. You’ll never become a fast driver.

@ Worm - ok first I don’t feel intimidated, you’re going to have to work a whole lot harder at that! I was speaking more for others I have seen discouraged from contributing their opinions. Isn’t it the nature of opinion that there will be differences? This is a forum, so what’s wrong with that exactly?

The two things I picked up on above are the damping and the ARBs. The bit about suspension stiffness was a ‘worth a try’ suggestion, and with a fatso muscle car that seems to be experiencing a lot of weight transfer, that’s always worth a look. The rear bump reference was based on his having the front bump at 4.8 and the rear bump at 3.5. The difference between front and rear bump was going to be contributing to the squat he seemed to be experiencing. If you read my second post you will see that I elaborated on this further. With the lively weight shift behaviour of FM5 there are definitely some cars that hold it together a little better with a slightly higher bump, but it’s one of those things you need to suck and see like anything else. The ARB point was based on the fact that having the rear ARB too low on a powerful RWD can again contribute to squat and bad behaviour on power down.

Too low of an ARB and you will get roll oversteer. It’s unmistakable when it happens.

No one is saying don’t contribute but it’s much easier if you search the forum or know what you are contributing. There are questions I don’t know the answers to so I ignore the thread or go ask someone else if I think they can help.

I know. :frowning: I’m teary eyed as I type this. But there is hope, got my first 1%

LOL

Well the last few posts all made me laugh.

Off to bed I go.

Is the dude that asked for advice even on here anymore? Lol, I wanna say I started 400 lvls ago by reading worms tune and watching some guy tune a viper on you tube…both set me in the right path…I tune all my own cars and they are very drivable only thing is I’m just a decent driver… Good job fellas I offered the guy a tune and would’ve spelled it out but given that I’m not forza-famous he prolly didn’t even try it…to each there own, iv tried leader board tunes so I can compare the feel and In some cases found them to be un drivable (ex. GTR720) which is really tricky. Thanks a lot for the great advice tho for sure

I didn’t know tuning was about right and wrong.

This explains a lot

Well, I’m going to eat my own dogfood and build a ZL1. I think everybody who has posted into this thread should do the same. I’d be interested to see the results.

Worm,
In your point by point rebuttal you mentioned that ARB’s should start out at 10/10 (I assume you meant for a base). In the “Universal Tuning System” thread you suggested 14/14. Which do you actually prefer? I was happy with the 14/14 start but I’m always willing to be happier.

@Worm, why is that everytime someone is trying to offer help you come in with your big shoes and try to impose your way of tuning? Yes i have offer some tips and they might not be of your tuning taste. As you said, don t send someone in different directions but at least send him in the good one.

I know you are a good tuner, no doubt about it. But it seems that you have the tendency of imposing your way and you do not agree at all at any other way of tuning. Yes your method is one of the best but its not the best. TPR, EMW and others might all go the same way than you, but there is more than 1 way to achieve a good set up.

When i started to tune, i learned a lot from your guide and from your suggestion. I am also french, i also learned from the top tuner of the french community with the open source tune of BAM a long time before they open their open source tune to the world and from other top tuners from the french community.

I also had the chance to learn from Holty and MJO Daney when i joined Pendulum. So i ve learned a lot from different tuning style, wich they will be good depending your driving style.

Your tuning style is coming from your driving style. And to be honest have been replicated by a lot of folks during the previous forza games. Different driving style will need a different tuning style.

Explain to me then why Onr Road runner is posting good times with his set up, wich is obviously quite different than yours, the BAM team is also very different than yours and yet they are posting top ten times all over the place.

I really appreciate your imputs about tuning, don t get me wrong. Just please stop imposing your own way and try explaining why were not pointing in the good directions from the start.

Cheers

Rosny

Even roadrunners setting’s are for the most part in the conventional range. Driving style more often then not is an excuse/crutch. Just like “I don’t tune lb cars I tune oddball cars” it’s easy to say such things when one hasn’t/doesn’t try to compete with the best. Further no one on this forum is worse than your own Greek the"god" of forza when it comes to putting one’s chest out. Seriously worshiping false idol’s is blasphemy. Just because one has learned doesn’t mean they can teach. The first thing that should have been mentioned but was overlooked was the lack of aero. How come such knowledgeable tuners let that slide?

Where did i say i m worshipping Greek, he is part of my team and he test my cars. He is fast and that s it. He can do what he wants, it is his own rights.

Instead of doing your little show and coming in like you seem to do recently, why YOU the top tuner didn t point out the no aero issue instead of putting fuel in the fire and try to help the new comer.

You use to be a big part of this community, helping a lot of newbie… Now, well…

Have a nice day.

Rosny, what did the OP say about the changes?

I ll get back to you, i m just re reading the op answer so i don t misinterpret anything. And i also had to give the bath to my kids, wife was yelling at me lol

Don t get me wrong, i m not here to start a war with anyone, i just want a cordial conversation. I can reply here or we can switch to PM

@Loco - How come such knowledgeable tuners let that slide?

lol because we weren’t preparing court papers but reading a forum post and offering some suggestions around its main query - namely difficulty getting power down out of corners. Also, from my second post in this thread:

"If raising the spring rates 50 pounds is causing sliding, given where you started then I would say you have probably reached your grip limit - unless of course it is just one end of the car coming unhooked. If you look at the friction telemetry, this will be obvious. You can either work with the drift, or add rubber or downforce. "

This whole debate is pretty silly. Nobody offered bad advice, just advice. Did we offer all the advice that there was to offer? Well, no. Was aero the biggest thing. Well, no. Looking at his build the biggest problem he had was with the exaggerated bump offset and the roll bars. A lot of people successfully build cars without aero. I like it myself, but it isn’t written in stone that you have to use it. I honestly don’t get why people can’t add to a thread like this without trying to get a leg up on previous posters. Nobody is a hero in a game. It’s just a game, right?

Loco I do have to say that is the first time “putting ones chest out” is used in reference with Bible scripture of blasphemy.

Everyone needs to cut out the insults.

Rosny, what did the OP say about the advice?
