No idea. But, it would possibly be helpful to know what code was thrown when you got the wrench light. If it happens again, check the diagnostics display for the "P-code(s)".
And, there's really nothing in changing Tire Size or Gear Ratio that should cause this, especially on Level 1. I'd also reload the Level 1 tune with those things changed and see what happens. (However, I think you get more benefit out of using the Level 2 tune.)
