First goal: display gearbox position 1,2,3,4,5.... without sensor.

1- create extra PID with this formula:
[0c]/[0d]
unit: rapport or what ether else
name: vitesse

2- create à digital dial that display this value when driving
3- write all vallues for each speed postion
4- create indicator display with this goal for on

1 speed: greater than (rounded value writed before)
2 speed: less than (rounded value writed before)
etc....

try
it work :=)

if you use icon with no transparency, you can superpose them to obtain a digital speed position display.

feaw tips:

PM is not displayed because extra pid as a value of infini
rear speed is same as 1 speed, can't make différence.
