TuneBoy doesn't care what state the bike is in (aside from ignition on). The
engine temp matters if you are going to adjust CO levels. There is a
specified temperature range where the ECU will let you do this. 2002 and
later have the O2 sensor which overrides any attempt to manually adjust CO,
even though you can tweak the parameter (idle fuel trim). Adjusting CO with
a gas analyzer (to 3%) is evidently very important on the pre-2002 models if
you want it to pull/run smoothly at low RPMs.

Correct. TuneBoy (cable and software) is about $200. The software key, which
is tied to your ECU serial number is another $100. The "starter kit" sells
for $310. Note that the cable requires a serial port on your PC. Many modern
laptops do NOT have a serial port anymore. They all have USB though. There
is exactly ONE model of USB-to-serial adapter that works with the
non-standard baud rate that our ECU runs at. It's from KeySpan and costs
about $40. So the total investment for me was $350.
