Having some issues with GEMS itself.
When you have the data loaded and try to switch from time to distance mode it's goes nuts.
As viewing data by time is nearly useless for comparison.
Any help appreciated,
DREAM Motorsport (F4, FFord)
Pedders Racing ( GT86 Australian Production Touring Championship)
All the basic steps worked perfectly: Download & install Perl, download GEMS & install application, download & install DLOG99 application, download & install Perl Text::CSV module, download the Perl conversion script, run it on a RaceCapturePro2 log file, import the resulting file into DLOG99, save it as .stf file, open the .stf file in GEMS. Yay!
When I clicked the GEMS View > Toggle Time/Distance to distance, I could no longer scroll the trace window left/right, and the cursor would only take huge jumps. Similarly, the cursor on the track map would only make a few jumps around the track. My "Distance" channel was good, incrementing smoothly to the correct lap length and resetting to zero at the start/finish line. But I noticed that the "Lap Distance (m)" channel would only go from 0 to 3 over a lap. As in a lap length of 3 meters. This also meant I couldn't color the track map with a channel, because apparently it only does that once per meter of Lap Distance.
So, I went to Data > Distance Channel Setup... unclicked the Distance channel in the first box, selected the second box "Calculated Distance" based on the Speed channel, (click OK, of course), and everything's suddenly wonderful. Lap Distance (m) is now correct, I can use both Time and Distance trace overlays, and the track map is all kinds of pretty colors.
I don't know where the Lap Distance channel is getting messed up, because I checked my .csv file in Excel, and the Distance channel there is correct, and the Distance channel in GEMS is also correct.
I hope this is helpful.
