Hi all sorry if this has been asked a few times but some of the posts are old and not exact info ,

Trying to turn off security in a 2010 300c 5.7
I?ve tried disabling skim and skim capable tab but ecu still won?t turn on the ASD relay
And when I manually turn on relay it won?t fire up

Can it be done and do I need latest version of up tuners
I?ve read the tune with my old dongle and using version 4.05
But nothing I do is helping and it won?t start,

I?ve got the original tune if anyone can mod it for me or is there anyone that can help
That would be great

Thanks
