新西兰问个问题关于新西兰油品
在新西兰
咱新西兰bp 98大概会相当于北美什么标号的的辛烷(octane)汽油？91 93 95.。。还是都不如lol 因为要刷ecu，开始关心这个问题了

汽油标号
是实际汽油抗爆性与标准汽油的抗爆性的比值，和汽油纯不纯或好不好没有关系，标准汽油是由异辛烷和正庚烷组成。异辛烷的抗爆性好，其辛烷值定为100；正庚烷的抗爆性差，在汽油机上容易发生爆震，其辛烷值定为0。如果汽油的标号为90，则表示该标号的汽油与含异辛烷90%、正庚烷10%的标准汽油具有相同的抗爆性。
汽车选择汽油标号的首要标准就是发动机的压缩比，也是当代汽车的核心节能指标。同时还随发动机的型式、空燃比、冷却水温、进气温度、点火提前角、气门定时等因素。所以不要妄自推测适用汽油标号，更不是标号越高越好，应该以原厂推荐和使用手册为准（动力部分改装车除外）。
研究法的辛烷值 RON = "Research Octane Number", octane number, which have been measured in the medium or low speed range
动力法的辛烷值 MON = also "Motor Octane Number" is the octane number that I measured in the high speed range
测量汽油的抗爆指数 AKI = (RON + MON) ÷ 2 = "Anti Knocking Index"
日本工业规格JIS规定，
普通无铅汽油的定义是高于89号，日本市场上贩售的一般是90～91号普通无铅汽油。"Regular" gasoline in Japan (Japanese Industrial Standards) RON 90 / MON 81/ AKI 85.5
高级无铅汽油的定义是高于96号，日本市场上贩售的一般是98～100号高级无铅汽油，对100号的正确理解应该是其辛烷值幅度在98～100之间。
"Premium" gasoline in Japan (Japanese Industrial Standards) RON 100 / MON 84/ AKI 92
美国主要是采用动力法的辛烷值 MON值标识
普通无铅汽油＝82
高级无铅汽油＝88
乙醇＝92
具体RON/MON/AKI数值分别为
"regular" gasoline in Australia, New Zealand, Canada and the US RON91–92 MON82–83 AKI87
"Premium" or "Super unleaded" gasoline in US (10% ethanol blend) RON97 MON87-88 AKI92-93
新西兰目前市面上主要是两种类型的汽油，普通无铅汽油（91# Regular）和高级无铅汽油（95~98# Premium)
"Regular" gasoline in Australia, New Zealand, Canada and the US RON 91–92 / MON 82-83/ AKI 87
Super/Premium in New Zealand, Australia RON 95 / MON 85/ AKI 90
BP Ultimate 98/Mobil Synergy 8000 in New Zealand RON 98 / MON 89-90/ AKI 93-94
通过MON比较而言， 美国和NZ标准对比普通无铅汽油值分别为82/82-83，高级无铅汽油是88/85（NZ 98# 为89-90）

Sport maps are designated for use with 91 and 92 octane fuel (95 Ron) or better. This mapping is less aggressive than our “Aggressive” mapping and has been developed to ensure safe operation on 91 Octane fuel.
Aggressive maps are designated for use with 93 and 94 octane fuel (98 Ron) or better.
Drive maps can be used by those who have access to “premium” 91 octane or greater in
the states of Arizona, California, and Nevada. This mapping is less aggressive than our Sport mapping and has been developed to ensure safe operation on ACN91 Octane fuel. Retains stock rev limiters for added safety. Alternately, this mapping is recommended for those seeking our most conservative mapping.
看来bp98只能勉强上sport map。。。。。
