问：关于改变MAF外壳直径的问题
我将尽量保持尽可能简单。
我有一个售后市场的摄入量，MAF壳体的储藏量小于库存。
在意识到摄入量导致我富有富裕的过程之后，我决定尝试“抵消”丰富状况的方法。
MAF传感器希望这会产生真空泄漏并导致更“瘦”的状态后，我在售后市场的进气口中钻了一个孔。
在使用了一堆数据日志之后，我发现在MAF住房（ECU未征收的空气）之后有一个开放式阀门实际上使我运行稍微富裕。
Please explain how this can happen.
我的汽车有自动变速箱。
你好呀。The oxygen sensor still detects rich/lean, regardless of how the mixture is calculated, and sends "lean it down" or ’richen it up" signals to engine management. If engine management is out of range on the combination of signals it knows how to operate with, it could be too rich, or worse yet, could default to an "open loop" mode, where it essentially gives up on rich/lean management (such as during engine warm-up where the engine is, by design, running pretty rich). Working with modified OEM systems that are not really adjustable is hard, and can easily produce the results, and challenges you are experiencing.
