How do I compare TUNED results with UNtuned results?

(this answer assumes you know how to create Simulation Bias settings using the Tuning Wizard).

Keep two databases. One with tuned results, the other with non-tuned results.
To implement:

• Turn "Use Simulation biases" on (Simulation menu).
  
• Load card(s)you are interested in.
  
• Connect to TUNED DB, run all sims, store to db.
  
• Turn "Use Simulation Biases" off. Connect to NON TUNED DB, re-run all sims, store to DB.
  

This SHOULD work dandy without closing the cards and re-opening them when you switch between "use biases".

TO COMPARE:

Now, start TWO instances of EquiSim. One should connect to the TUNED DB, the other to the NON TUNED db. Put them side by side. Go to the SPAT in each, compare visually.
