I suspect this is either proporitery information or you don't want the possible blowback from saying anything, however, I'll ask anyway. Would you be willing to inform the public what you found in more detail once the tune is available? I'm mostly just curious. Comes with my physics background and tends to ruin conversations.There is a lot of mis-information regarding the cause of the engine fires and the redesigned egr cooler. The new cooler is the same part that is now used on the 2020 engine. Externally it is dimensionally the same, but on the inside the wall thickness and internal plating are beefed up slightly. Of course, this is a placebo to placate the masses and will not solve the fire issue. We have found two issues in the latest FCA calibration that lead to excessive manifold temps. These are both being solved with the new tune we are in the process of certifying with CARB and EPA. We hope to have a real solution out in the field in the April time frame. All of this nightmare could have been avoided with good engineering.
