My main question is, after I get my AFR Error % the closest I can to 0, will I still run rich in comparison to Closedloop?
You will run whatever a/f you tune it to. The a/f will not change from your tune in open loop. However the car will run richer as the air heats up and leaner when the air cools ie-winter to summer. You can compensate for this by the AIT.
