Looking at the tech pic on the Readspeed site,it seems you set the base timing and then switch settings without altering the base setting,unless its within a certain range of what you need.
As with all these things do you have to rev the engine to,for eg 6000 rpm to check your timing at those revs or is it ok to see the timing heading that way?
