UKGTR Season 7 Lower Endurance (GT2/3) - Interlagos - Feb 17

[Dave 'Gizmo' Gymer]

Many add-on tracks have the overheating tyre problem, which is best solved by changing the .gdb file.

Thing is, I've compared the GDBs between the SimBin originals and add-ons and there's either a placebo effect going on or there's some sort of cunning hack being used on the SimBin tracks (like artificial positive camber), because the grip numbers are generally the same.

I have no idea which corner or curb, if indeed it was a curb. Not seen the replay. That's not the point, I was simply driving a normal race and it spoilt my fun which is a real let down considering I only race for fun. I don't think I'll be racing this track again or any other 3rd party track in GTR 2 as I've had enough of problems from dodgy amatuer tracks giving extra discos, crashes, car flipping antics, cars stuck in the track, being placed off the track at the start and so on. I really do have better things to do with my time. 

When you look at the replay Simon you might change your mind a bit. It looks like you took a bit too much inside curb, which made the tail swing out, so you dialed in opposite lock. As soon as the front tyres came off the curb though they regained a lot of grip while pointing right, so the car snapped back to the right. It then slid sideways across the track and off into the gravel. The problem was that the gravel is at a lower level than the track, so the car intially flew through the air. When it landed it then dug in and rolled, which is not completely unexpected. The question that needs asking i suppose is whether the gravel trap is really at a lower level than the track, as cars are always likely to dig in if they hit the gravel when airborne.

The reason why I brought that up, is because at S.nl they use a changed .gdb and it fixes the tyre overheating problem.

ONLY FOR TESTING, AS IT WILL CAUSE MISMATCHES!

LOL. Sounds cool, I'll need to check it out on the replay as it sounds spectacular. As I said all I actually remember at the time was flipping maniacally through the air and wondering which country I would land in. I don't remember losing it or anything, so that's interesting to hear that I did lose it and then some moles buried in the gravel decided that was a good time to pop up and flip my car through the air like a exocet missle. It was all a complete blur and then watching my poor Viper with it's legs in the air trying to be rolled over by a tank (Gizmo's Viper) was mildly amusing. I let it sit there for a lap afterwards so you could all get a good gawp as I thought it would amuse you all and I was far enough off the track not to be a danger.

Gotta say thanks to the guys who made lapping easy, i know you guys had your own race, so cheers for that.

Thanks, I didn race much anyone, I raced for last
But I just wanted to make it clear that even though some of us give way easily when being lapped, don't take it for granted. Before you know it you're on the inside lapping a car that's planning on cutting the corner. So even though it's nice for us backmarkers when you pass fast, so we can get back up to speed, it's not always the car in front is aware of you. And because I have the light switch on my keyboard, it's not always easy to reach.

[MortenS]

We all had that problem Dave. I was runng 230F+ on the rear right most of the race last night.

And I took the other alternative, I took it easyer.

What abou the Attrition the, I just took a quick look, and I don't know what it stands for here, but all three Simbin tracks I checked had 15, but Interlagos had 12

But as I can see from the other version posted, the rear heat has been adjusted, in the same way as the Simbin Monza track.

But what I actually noted when checking with Motec, is that (didn't check when I braked) my tires always had higher speed than the gound speed Even the front tires, both at the same time.

THat's to do with how often the AI get technical failures.

The numbers JR's talking about are:

Code:

  FrontTireHeatMult = 1.00
  RearTireHeatMult = 1.00

What I don't understand is why the same numbers as are found in the standard GTR2 tracks don't work with some addons.

[MortenS]

Check the Simbin Monza track

[Dave 'Gizmo' Gymer]

Check the Simbin Monza track

Interesting... now Monza is known as a low tyre wear track... is that why? I suspect Parabolica is to blame...

Not much of a "sim" though is it if tyre wear is measured using fiddle factors and not slip angle and heat!

[spanner]

I always thought Interlagos was a high grip/ high wear type circuit. Its supposed to be an abrasive surface?

[Kerr]

It's the only circuit I've ever raced that my tyre temperature increased on the main straight.

If you mean the long long long left hander then "duh"...

[Minton]

Terrible race for me....   Took over the lead when shark crashed looked very strange defantly some sort of bug,    Kept the lead for a few laps then made a mistake and went down to 4th .
Made my pitstop and had no pit crew so had to go round again and make another stop which totally ruined my race.
Drove the car way too hard after that got fastest lap but buried the car in the process.
Well done to all who drove consistnantly ,was a very hard race i thought.
Cheers

I'm travelling without applying any steering lock yet tyres at the rear increase a couple of degress travelling past the pits
