I purchased an Edge A2 Monitor from a guy that has an Excursion the same year as my F250. I plan to use the A2 as just a monitor and get an SCT Tune in the near future, but was wondering if I can still use the pre-loaded tunes that are in the Edge in the meantime? I plan to be road-tripping this weekend and would like to see some better fuel mileage. I don't have any major performance upgrades so I would plan to just run it on level 2 or 3. Also, is there any "learning" time for the truck to understand the Edge once I dial up the tune? Thanks in advance for any info!
