Thanks Jake, let us know how your first outing goes.
Victory - With I-Lap, there is no limit to the number of cars at once, as the transponders all have unique 7 digit numbers. When it is connected to the computer, the computer can't tell the difference between it and an AMBrc. Some of the softwares limit the cars to 20.
I have had a few Trakmate users contact me in error with problems and I was able to get them going, so I may be able to help you.
Are you using a USB - Serial adapter?
