I can no longer use the “launch control” method using e-brake>throttle>clutch>tap e-brake until to desired rpm. I was able to do it fine up until a couple days ago and now no matter what car I switch to they all shoot up to about 3000rpm when using throttle then drop down to 0 and repeat. I have un-installed and re-installed, reset all setting to default and just switched ONLY transmission type to manual w/clutch, HOWEVER only sometimes when I use the last method can I get the launch control method to work again, then I switch cars (to one I KNOW can do it no problem) then I can’t do it anymore.
This is really annoying and I’m sure any input would help.
