Conversation Between Just Strokin and rfree

Strokin,
I have a forscan ? Trying to enable DPF%. My code now is 720-01-01 EA20-BA20-EF5F
When I change the value from B to 9 I get a checksum error. I do have compass enabled from factory so that value does not match either. I noticed most people have are EA21 where I have EA20. Any suggestions
