This IMSA series isn't super popular. I think a result of that, less money, effects the broadcast and getting things like telemetry on the screen. Just a theory. At Le Mans you get all of it. The P1 and GTLM cars are all going to Le Mans. The rules are exactly the same regarding engineering.
@Pᴀᴜʟsᴛᴇʀ2 Totally agree. The broadcast itself on FS2 has had poor quality data. It's taken away from the show and creates confusion as to placement. Plus....no telemetry.
