I have 2 double pumps but I want to have 1 single pump and 1 double pump I follow the instructions but it wont work unless im doing it wrong
My impala 63 should be single and lincoln double.
But impala is double

when your ingame click on the hydraulics button and select what pump you what on which wheel if you have one on 1 on and one on 2 its double ,if you have 1 on one and 1 on the other its single.hope that helped.

Ya it did
thanx
But for single pump it has a low suspention but only when i vers al.
But wwhen im not it goes high?
Is is cause its single?

Yeah that is because there are restrictions for single pump and there are restrictions for double pump.
