UKGPL Season 32 (2017-18) 1955 Grand Prix - Monaco - Oct 10

[francesco]

You may be hitting the throttle pedal a little early but what about the downshifts?  As I recall is was usually an early downshift that the motors didn't like.

If the down shift is the avg,revs.dropped they are:
Me.21471,891,271,1004
Andreas:1519,607,620,639
Dave R:21471,60,217,10737

If are the revs-,during the lap all my number are - excluding one that is +150

For the record, I still had issues joining UKGPL 9 yesterday. I re-booted the computer and finally managed to join the server afterwards. Great I thought, but Dave Curtis had a similar problem and he could only join when nobody else was in the server. When I did finally join, also nobody was in the server. When I couldn't join earlier Clive was in the practice server. Coincidence?  More investigation needed  .

I could be wrong,  but maybe all the full complement of UDP ports are not open to/from UKGPL_9?
Maybe only a few of the 21 'racing connection' port range are permitted?

From locating the igor technical documentation [never needed to find/look at that before!]

• iGOR->Help->HTML documentation]
• Documentation section -> iGOR Technical

It states for the GPL ports:

By default, GPL uses the following ports:

Broadcasting
Port 6970 (UDP/outgoing)
- used by GPL to broadcast the status of the races to the RaceList server.

HOWEVER, iGOR changes this port to 30199 (UDP/outgoing) to keep the range of ports required by iGOR to a single block (30196-30199).

Pings
Port 6971 (UDP/incoming)
- used by GPL for ping responses.  Not used by iGOR.

Racing Connections
Ports 32766-32786 -- 21 in total (UDP/incoming)
32766 is used for incoming connections,
32767-32786 are used for existing connections to each individual client.
- if you are hosting a race you will need to open/forward 32766 to 32766+n, where n is the maximum number of players you will be allowing to join your races.  e.g. for a 6 player server, you will need 32766-32772 inclusive.

When I just joined & was alone,  my connections were:

• UDP: my_pc:32767 <---> ukgpl:32766
• UDP: my_pc:32767 <---> ukgpl:32767

So maybe the 32766 is the initial connection & each player is allocated subsequent ports from 32767 [that's what the documentation seems to say anyway!]


Cheers,
Dave.

I don't understand what the figures are but I would have said that any of the '67 GP Engines doing more than twenty one thousand rpm is doomed.

Yes but in this case why my engine explodes and that of Dave no and we have the same avg.revs of 21474.Is only bad Luck?
Anyway this 21474 seem a program error,there is no way to obtain it from the data,conversely all the other are median obtained from data.
Unfortunately,on the site of GPL replay,there is no explanation about this data

There is a random, "luck", element.  I can recall that one guy had a Brabham die on the grid.  The engine life is not a constant.

You can only trust your own saved replay!
Revs of >20000rpm are ridiculous false...
The column of "avg Revs dropped" seems to be wrong or adds all!

For me the main info is in the top middle, the number of speedshifts per lap! The more the shorter the life of your engine...

speaking always about the lap 4 i have 12 upshift and 1 speedshift,Dave 14,7,Andreas 10,0.Again i'm not able to understand.
Excludind the 66 until now i have had 2 engine blow with the Lancia 55 at Bueno A.and one smoke with the the Connaught at Monaco.
Seem to me enough to exclude bad luck.

[Cookie]

Look at your shifting avg revs!

Driving a Gordini at Spa with max 6000rpm :



or Monaco lap4 Connaugh max 6400rpm:

[francesco]

So Axel you say that is the around 10000 revs at Rouen the cause of my break?In this case is enough to change gear before.
At Monaco,with the Connaught,i don't remeber exactly the lap but was around the 15.In this case the engine was not exploded ,have produced smoke loosing speed.

PS.I'm not able to find again the program to post picture in this forum.Could you give me it another time?

[francesco]

I have found the program for the pictures but i don't remeber the method.

[Cookie]

Your avg revs are allways too high ~10300rpm :



You should look into the data of the car and look for the revs at max power. Just try to keep your maximum a little below it...

[francesco]

Ok ,thank you Axel.

Yes, those ports are open and forwarded to the server, if they were not connection would be impossible for all clients, not just an apparent select few. It is as you say from what I looked at the connection flows - 32766 is used to then negotiate with the server the actual port for that client, i.e. 1st in has 32767, 2nd in has 32768, etc.

Yes, I think that's how it works, all that range should be open.

[miner2049er]

Since the high number of engine burned,I'm investigating on my error or possible malfunction of my gas pedal.

Are you lifting off the throttle during a gear change?
