Y connector for speedo?

That makes a lot of sense.

Is there any chance that a TSR-like program could be written that intercepts the data right before it is written to the log and changes it? I'm sure there's got to be very little memory to play with in there, but maybe a super tiny assembly app could do the trick?

Of course, there's still the issue of starting the app up in the first place...
