Pit Board In 69 Mod

Today, 03:30 PM

Posted by twinpotter in GPL-"Help! I'm having trouble with..."
Not sure if this is feasible or as been asked before. Don't know why I haven't seen it before?

Anyway in 69x mod, using High Wings on the Brabham, at Kyalami. When coming round to the S/F and seeing the auto Pit-Board,I can't see the info because of the front wing.
Small issue,but wondered whether rectifiable?

Thanks  :hat-tip:

Tire Temp Diagnostics

Today, 02:19 PM

Posted by John Woods in GPL-Setups/Replays
Fluke Corporation makes thermometers that are used by race engineers to measure tire temps.
The link below goes to a page on their site related to tire temps and setup tuning.
It includes a graphic showing the info below, along with the article on tire temps.


From the table:

"Use the following table as a general guideline to interpret readings and make adjustments to the car:

Symptom Diagnosis

Center hotter than edges
Tire pressure too high. Reduce 1 psi for each 5° F delta

Edges hotter than center
Tire pressure too low. Add 1 psi for each 5° F delta

Inner edge hotter than outer
Too much negative camber

Outer edge hotter than inner
Not enough negative camber or too much toe-in

Tire below ideal temperature range
Tire pressure too high, tire too wide, or springs/sway bars too soft at that axle

Tire above ideal temperature range
Tire pressure too low, tire too narrow, or springs/sway bars too stiff at that axle

Front tires hotter than rear
Car is under steering (pushing). Too much front spring/sway bar, not enough rear spring/sway bar, front pressure too low, rear pressure too high, front tires too narrow, rear tires too wide

Rear tires hotter than front
Car is over steering (loose). Too much rear spring/sway bar, not enough front spring/sway bar, rear pressure too low, front pressure too high, rear tires too narrow, front tires too wide"

Syracuse '67 Home Footage

25 Aug 2016

Posted by Elijahroberson in Motorsport Chat
I found some home footage of the 1967 Syracuse Grand Prix
It includes Scarfiotti and Parks dead heat at the finish. Looking at this and the GPL track there are some differences on the front stretch, but I like the GPL track the way it is

Spa '67 Replay

22 Aug 2016

Posted by Peter Dron in GPL-"Help! I'm having trouble with..."
In GPLRank's World Records, there are two recorded laps for the Lotus, both by Harald Podzielny, one in 3min 16.7sec, the other half a second slower; he has also done a 3min 15.8sec lap in the Eagle.

These laps show up properly in GPL Replay Analyser, with a top speed of over 199mph on the approach to Masta.

However, in GPL Replay, it is in slow motion, the highest indicated speed is 120mph and the lap takes about five and a half minutes.

They key to this is in "Comments" in GPLRank: "Run at 60fps."

Some questions:

1) Should I be running at 60fps? If so, how do I do that?
2) What are the advantages/disadvantages? I presume, for example, that if one switches to 60fps, all the existing replays will be in 'fast-forward' mode...
3) Are there any other recorded laps of the Lotus at this circuit? (I am interested only if they are below 3min 20sec.)
