Quote from: Myst1cPrun3 link=msg=106032After some testing, I believe I have come up with a theory and a possible solution to the seemingly random front end crashes, as well as the issues with camber changes mid corner.

(Thinking MG hairpin at Victoria)

I did touch on this in a previous topic before it was moved, as it got way off the original conversation point. (As much my fault as any that was so I apologize)


Until I started fiddling with tyres, I thought the front end crashes on camber changes was because of the suspension, and a lacking part in the simulation or mod..

However, in the tyre files, max lean can be set using the DX1 and DY1 values.

Now this differs per front and rear tyre so you can have a tyre have a larger max lean angle than the other.

The bike will only lean to the angle of whichever tyre has the smallest max angle.

So for instance if you let the front have a higher max lean angle than the rear, it is the rear that'll determine the total bike lean.

This becomes important in camber changes.
It's no secret the front tyre is narrower than the rear, so in terms of lean angle, it has a slightly different steering rate it seems. (Not sure on Reasons or physics behind this just how it seems)

If you are on the max lean angle of a tyre, and then the camber changes, the bike does not get stood up, the lean angle changes to beyond the maximum set value in the tyre file, and a crash occurs with seemingly no warning. Typically these crashes are front end crashes as that's the narrower tyre and it's also what it's the camber change first.

As a result I found giving the front tyre 0.1 extra lean on the  DX1 and DY1 values when compared to the rear tyre helped a lot.

This extra angle doesn't affect the bikes handling on the flat, as the rear tyre will be the limiting factor, but when the camber changes, it means the front doesn't simply 'fall off the edge' like is known to happen in GP Bikes.

This isn't to say you can't crash, you can, it just adds a bit of control of the bike over camber changes.

Here is an example of the M2v2 at the MG hairpin, where I was being quite aggressive on approach, and could make the apex confidently, despite the known issues.

It is a marked improvement, but I am going to do more tuning when the 'big tyre update' drops for the v2

With modded bikes seen issues in the shader when activating HDR

Bug Reports / Brake Temperature Issue
November 20, 2018, 09:08:22 PM
I think there is a issue with the temperatures of the brake discs.

After 3 laps the front discs have more than 1600ºC of temperature.

Suggestions and wishlist / PaintED - DDS format

I would like PaintED application to be able to support paintings in DDS format.

Bug Reports / Game crash in garage
July 19, 2018, 04:30:42 PM
The game closes directly to desktop when i go to garage or save setup (It does not happen every time)

Edit: It seems to be an error in the new 64 bits version and apparently also with windows 10. The compatibility mode with windows 8 does not have any effect.
Bug Reports / Chain lods not work

The chain becomes invisible at the lod levels. It also happens on the default game bikes.

Moto2 Championship 2018 / Moto2 17 v.1.5 UPDATE
April 13, 2018, 10:55:38 PM

Changelog v.1.5:

Found and Fixed bug in tyres physics that cause strange rear suspension movements.

v.1.4b bike setup still compatible.

I would like a contact penalty system added in the next update of GP Bikes.

CBRP System (Contact Between Riders Penalty)

That is, if the rider hits another rider, they receive a penalty. Depending on the speed or magnitude of the impact, the penalty will be higher. It would also be cumulative and at the sum of "x" impacts the rider is disqualified from the race.

For example:

1x - 1x/5x If one rider hits another
2x - 2x/5x If it collides again with another rider

And so on until you reach a limit of collisions (5x) whereby the rider would be disqualified from the race.

Edit: As there is no way for the game to know who hits first the sanction would be for both riders. It may seem unfair but iRacing uses this system and the online races are the cleanest I have ever seen.

Bug Reports / Rear Suspensión Bug
March 04, 2018, 07:13:11 PM

I found a bug with the the rear suspension physics. In the Moto2 2017 MOD you can see that after several laps on the track the rear suspension stops working leaving "loose" sqingarm making the bike very difficult to control.

I have had several reports on this matter and I can not find a possible explanation. I hope it can be solved soon in the next GP Bikes beta.

Suggestions and wishlist / My wishlist
February 13, 2018, 05:59:14 PM
I have a wishlist that I would like to see on GP Bikes.


  • Engine pit limiter sound
  • Backfire sound & gfx
  • scratches, dirt and rain bike layers


  • Possibility of choice custom HUD's
Suggestions and wishlist / 3p HUD customzation
February 13, 2018, 11:31:16 AM
I am currently working on this HUD. At the moment it is partially functional. http://forum.piboso.com/index.php?topic=5636.0

I would like PiBoSo to add some functions:

Possibility of adding a rpm graph
Possibility of adding digital rpm
Possibility of adding rpm LEDs
Possibility of adding digit padding
Possibility of adding neutral light sprite
Possibility of adding sprite optimal engine temperature
Possibility of adding cold engine sprite
Possibility of adding current lap time
Support / Custom digital HUD. Is possible?
January 24, 2018, 03:01:31 PM
I'm trying to create a digital HUD but the game code only shows the possibility of an analog HUD.

Is it possible to create a fully digital HUD?

The HUD contains rpm lights and also a rpm graphic.

Suggestions and wishlist / Time to improve ECU
December 05, 2017, 08:39:29 AM
Piboso, it's time to improve the ECU.

This simulator deserves a better ECU simulation. We can't continue with such a rudimentary ECU which gives more problems than benefits. I don't know if this is on your list but please keep it in mind.
Bug Reports / Anti wheeling makes wobbles
December 04, 2017, 11:10:24 PM
The wobbles seem to be related in part by the aw.

Every time the front wheel tries to get off the ground the aw acts by cutting the throttle and when the wheel returns to the ground the throttle is opened again creating a resonance that gas open / cut producing a wobble.
