@Black-Square Thanks for the detailed explanation, Nick. That makes sense, and I understand why it’s not a quick fix.
Given the current limitation, where fuel flow first increases when leaning before it starts to decrease, could you please advise what procedure you would recommend to achieve the most realistic results in practice?
For example: should we ignore the initial increase and simply continue leaning until we reach the expected EGT / performance values, or is there another “best practice” you’d suggest until the new fuel/mixture system is implemented?
