Hi Members,

After some long testin days we setup the drivetrain very good.

We just have one problem with the shifting.
We dont want that the driver can shift into neutral during the race. So we have split the downshift lever and block the output signal when the first gear is reached through a microcontroller.
Now we will remove the microcontroller from the steering wheel because it takes much space and it was just a short solution.
We also have a neutral button on the steering wheel wich we want to use as a digital input like the down and upshift levers.
So we setup the input of the neutral button to the function Gear Neutral Switch.
But nothing happens. On the live time graph where you can see all changes when you shift is no change. Nothing.
The Gear Neutral Switchjust shows On when i press the button and off when not.

So i opend the M1 Build an saw that the Gear Neutral Switch is not used for anything. It isnt in a shedule function or somewhere else and let the actuator operate like the down and upshift lever do.

Did Motec forgot to set this function in calculations or am i not able to setup the function right?

Thanks for answers

The Gear Neutral switch is intended for gearboxes (like bike engines), that indicate when the gearbox is in Neutral (normally you'll find that hooked to a neutral light on the dash). This information is passed along so that the dash can turn on a light if desired, or logic that only allows the starter to be energized when in Neutral can be utilized in the PDM.

You have control of the firmware, why don't you change that to Neutral Lock Switch or similar, and change the behavior.

Hi,

As David said, the Neutral input is just to indicate that the gearbox is in Neutral, to have GPRP lockout downshifts into Neutral whilst the driver is on track, what you need to do is to allocate that switch as a Clutch Switch, this will then block the downshifting into Neutral from First unless the button is pressed.
