PLEASE HELP! Car is not idling properly after MHD install.
Hello,
I have a 2009 bmw 135i
Trying to install mhd and my car isnt dealing with it correctly.
First install stage 1, no options on. Car started and idled fine.
Then i added burble option, started car and it idle stuttered very hard.
Removed burble, continued.
Went to stock mhd options on, continued.
Flashed to oem, still stuttering idle.
Is there any way to fix this with the app? I need the car running tomorrow.
