Anyone?
You can set it at 50%, so you just double your speed indication to get your actual speed. That effectively defeats the speed limiter too since there is not much chance of going 372 mph to kick in the limiter showing 50% speed.I re-calibrated my Speedohealer the other day and came across this little gem:
"For 200 mph runs, set the Speedohealer to -99.99% correction factor"
Tried it (the reset, not the gonzo run) and the speedo needle wouldn't even move. Apparently, as long as the ECU doesn't sense you're approaching 186, no limiter kicks in.
