RPMS only updating after getting X velocity

[Juzerx27]

i have a problem with a vehicle RPMS, it only updates after some speed, i dont know what it could cause it, i tried a lot of things but it doesnt work like it is supposed to, here is a demostration of my problem

here is the blueprint to get the RPMS if you will ask me to cast it like it should:

and here is the torque curve:

i know that it looks like it is the problem but it isnt, the shape is just for testing, and here is a bit of the mechanical setup:

if anyone can help i would be so grateful, anyway ill be waiting for any solution.

i have found another clue, it not only happens when starting the vehicle, it happens when the velocity is lower than X value, after that it starts to register the RPMS, so im leaving out the bad setup of wheels, physics asset of the problem, ill keep experimentating with it until i maybe found a solution or someone knows how to fix it

okay, this is going to sound a bit stupid but it has to be with the gear ratios, this problem can be fixed by just adjusting the gears, eg: i had the same problem with other vehicle:

this is the configuration before, and i woulnt detect fine like it is supposed to do, so i fixed by cranking up the first gear:

this kinda fixed my problem, obviously i have to adjust values.
note if you have the same problem in other gears you should increase the ratios in the gear youre getting trouble, and thats it
