I haven't pushed things too far with the latest programming. I seem to remember talking with John about the engine rpm and vehicle speed limit settings. I asked for 4000-rpm as the programmed max engine speed, and we talked about removing any sort of programmed vehicle speed limiter. So, with an engine rpm limit currently at 4k, and with 2000-rpm currently producing 80-mph, the theoretical vehicle speed limit is.... a little scary. I've not tested the theoretical. I heard once that "there are old pilots and there are bold pilots. But, there are no old-bold pilots."
