Rpm stuck at 2k

Hey guys I have been having an annoying problem not sure if it even is a problem or something got enabled that I didnt have before. This started happening after the latest big update where they added some rims and cars I think, anyways I am using the etk k series trackday car and I want to do a burnout like I always do but the rpms just stay at 2k and I know its a awd car I switched the trans to rwd and changed the rear diff to the race one. Not sure why this happens and it happens with some other cars too.

Here is a video:

Thanks!

 

you need to setup your launch control rpm. try assigning some controls to it

 

There are no options for launch control under vehicle or vehicle specific.

 

Look under powertrain in the radial menu

 

I think its called two-step, for me its the '\' Key to disable it

 

Thank you
