Harry's GPS Suite Forum

Hello,
i'm willing to modify the Nürburgring GP track for ourselves.
In the GLP Competition, n-rounds (i think its 3) count as one round for the measuring system.

I thought about editing the track with a finish line (width=small) set to the far left, so we dont trigger it on the first 2 laps, since we drive on the right then.
I guess i will have to copy every other gps coord. 2 times, so laptimer doesnt get confused.

Would that work or is there a better option?
How big is the finish line with width set to "small"?

Greetings
Nils

You can find the corridor widths in LapTimer’s expert settings. The current accuracy readout is added to both sides on top. So in case the corridor is 10m, and accuracy is 5m, LapTimer will consider a width of 20m the s/f line - 10 to the left and ten to the right of the GPS position. Furthermore, you need to change the Wide Corridor: in case the track set features “directed triggers” (those with a driving direction), the wide corridor is taken.

On the approach in general: this will not be a stable setup. Trigger detection with (comparably) low accuracy devices is a challenge already. It is hard to divide a track into two triggering regions reliably.

Due to the above math, you will need to place triggers outside of the actual track.

Thankyou for the fast response.

If i get that right, the start/finish line is not the biggest problem if i set it to minimum and place it out of track, but the triggers on track wont work aswell?

I guess, there are no other options than that?

Thanks in advance
Nils

Hi Nils! Your idea of placing the finish line on the far left sounds good, but keep in mind that the "small" width is about 1-2 meters, so it might be tricky to avoid it on each lap. Instead of duplicating GPS coordinates, try setting up sectors for each lap.

You could also test it on shorter tracks to ensure the system doesn’t get confused. If the issue persists, fine-tuning the GPS points might be your best bet
