Forza Four Tuning...

[TopBoost]

Fit? Runnin' yer mouth about the Chevys??? We're gonna have to do something about that.  I got a fat-ass Impala just waiting to clog up the corners...

[BarbecuePete]

Fit, need some back up?

I ain't too keen on them flashy Chevy boys either, more of Ford man, plus you know Nova means 'No go' in Spanish right? So shouldn't be to hard to send em' back where they came from with their tails between their legs..

Its all in good fun.  Having a bit of incentive to chase a benchmark is what this game is all about.  Once the faster car emerges the swarm either hops behind the wheel or goes in search of a new rocket.  I'm in search of a new rocket.

Fortunately I also learn by doing and trying to piece together a competitive car has taught me a thing or two.  Last night was the anomaly night.  Two cars back to back with outlier tendencies instead of mainstream setups. 

No matter what badge is on the hood I'll be chasing the "NoGo" until I find something to keep up with it or outrun the thing.  Worst case, I'll get one myself and have a crack at it.  Once I run Infineon in the top secret cars and compare laptimes I'll post more notes.  There may be more going on behind the scenes than we think with tunes.

After reading your post today about the mystery cars & tunes, Fit, I went back & re-read the old Blooze Tuning threads about the Wb & SWR, etc.  Good reading. 

What do you suppose the T10 guys have finagled with behind the scenes?

   Blooze,

   Thanks for the Bel Air tune.  I took it out in the World Tour, and the British voice took me to Silverstone, then to the Nurburg GP.  Great fun running among the Fits and Scions, etc., and beating them pretty handily.

   After I was done with them, he sent me to Le Mans.  Wooohooo, now we're talking.  Blew their doors off.   

   Off to see what's up next.  Thanks again.

Lets try this again. I have another transmission sheet this time using a progressive gearing algorithm. Going from a standard gear spread to a close ratio pattern is just changing a number.  What those numbers should be is still up to the user to determine, but I've included several examples.

The sheet should be protected protected when you open it, such that only fields the user should be changing are editable.  Just go up to Tools->Protection and Unprotect Sheet to remove that if you want.  This could be used as a base if you wanted to strip the gear calculator I have and put in a different gear spreader.  I've also made it so that plots and calculations work on transmissions with 3-6 gears.

I'll have to try the trans sheet.  My FM3 trans sheet has let me down the last two cars and I have been winging it to make the shift points better.

Curious.. This guy says that per Dan (I'm assuming Greenwalt or whatever his name is) springs and wb's are now unique for each car and not generic like we're thinking.  That being said, my fm3 tunes are working in fm4 but they do feel a bit different.

What I have seen is almost identical default settings for the muscle cars I have been working on.

SWR = 44.xx% with a 51% bias
Total Shock = 49.xx with a 55.x bias
Total Rebound = 14.8 with a 51% bias
Bump = 78% of Rebound.

That is the same as it was last year (maybe a little softer with the ARB)

I think Tire Grip is the biggest changer.

Maybe it was talked about early in the dev cycle and got scrapped closer to launch?  I'll look at some of my garage and see what they are.

Here's the paragraph I saw on his talk with Dan:

     "From speaking with Dan the spring tuning and adjustments have changed drastically from FM3 to FM4. Every car is now different based upon what it is in reality
      as opposed to just one generic suspension being stuck under every vehicle like Forza titles in the past. (his direct words were not all suspensions are the same
      and the same springs weights don't do the same thing on every single car)"

From this, I would assume that the changes were more in the suspension modeling, meaning they redid the way each suspension type acts. So generally speaking, solid axle cars should have a generic template, a double wishbone should have a generic template, and so on. I think that VVV Worm may be reading too much into what was said.

[Blooze]

Sometimes folks get to thinking too much car and not enough computer program when dealing with tuning.

Feuerdog made the comment that the differences in the suspensions type applies to stock suspensions only, once you put on the race suspension it is all the same no matter what car. I am not sure where he got the information but from what I am observing I would tend to agree that that is how it is playing out in game.

[PhantomGinn]

Yeah, I would like to see what information he has. In the mean time, here's the "evidence" I can offer. Here's what I did. I took a DMC-12 and a 2010 GT500, put them both in B class, same handling stats. Basically I wanted engines in as far opposite locations as possible while keeping rear wheel drive. Then, I set the spring rates to the extremes to see how they would handle (max front, min rear, then max rear and min front). Afterwards, I set the spring rates to 750 lbs/in front and rear. All other settings are kept the same. After running some comparisonal runs, the two cars handled very similarly. There were some differences, but I think that was because of differences in torque, power, and stock ARB settings.
