Hi , I am trying to retard the timing in the WOT settings, but when I check the log I see little change , Iam at - 20 % and only get 0.5 deg retard.
As I need to get to around -3 deg retard ,would I be better off using global spark adder for retard when using nitrous . Thanks

yes, use the global.

OK ,thanks ,just out of interest why do the WOT timing settings have so little effect on the max spark setting?

How do you change the global spark settings? I only have an option to change WOT spark. Is this updated through a revision, or just an option on certain tuners? I have the U7000 series for a 2000 Mustang GT.
