I'm on my 2nd week with my Gen2 EX6. I went for the additional front and side shelves and Weber cover (oh yeah, and three shiny new 9930 grates from RCplanebuyer). Cooked pork ribs, flanken beef ribs, beef short ribs, some veggies, and a turkey. All came out great! There is a learning curve and I'm still figuring out best way to cook with this thing. Under 300 degrees F, Temps are fairly even across all three grates. Above 350, the right side starts to heat above the left side. Cooking the Turkey at 325F, the right side averaged a full 90F above the left, However, this did not affect the results which was a GREAT bird. I monitor grate temps using my Thermoworks Signals and a couple of High-Temp ambient probes. Today, I ran the EX6 empty with two probes (Left and Right grates) for a couple hours, adjusting the WSF temperature and recording the results. The EX6 lid remained closed through the entire exercise. I graphed the Left and Right grates, and the WSF "set temp". See the attached JPG for WSF setting Vs actual grate temps. Prior to above exercise, I cleaned the fire pot, grease channel, and made sure the EX6 was level, and that all the parts were installed correctly and well centered. The left grate temp seemed to match the WSF setting at each temp, 200F through 500F. The right side however ran hotter at settings above 300F and the difference (error) increased as the WSF temp setting increased. At 500F setting, the right side exceeded the Thermoworks probe limits (560?) and stopped recording. As the grill cooled, the right side probe starting reporting again. I've attached a graph of today's exercise. Like i said, still learning and will post any new observations / ideas as I have time.
