Did some coding on my M3: Instant mpg and Digital Speed Corrector. Instant mpg is an addition indicator (which you cycle thru with your BC button) that will give you INSTANT mpg based on what gear you are in and where the throttle is. If you let off the throttle, it will read 99.9 (hince: no throttle) but once you apply throttle, it will calculate your mpg. Digital Speed Corrector is also another display which you cycle thru with you BC button which will give you ACTUAL ground speed. Everyone knows that the Speedometer and Digital Speedometer is set to read about 5% faster than your speed…but know I can tell how fast im ACTUALLY going.
