Yan NDRG Posted November 17, 2022 Report Share Posted November 17, 2022 Hi everybdy. I have a question about MAP limit and Statistics. My car runs gently 200-210 Kpa, so I have set the map limit to 220 Kpa. But when look at stats, there is always MAP Limits Counts with some numbers. I set the MAP limit to have a try @ 236Kpa, clear stats, and then, I can see MAP Limits counts : 2 but MAX MAP is : 201.9 Kpa. I can't find what is wrong... Thanks for help. Regards.

Adamw Posted November 17, 2022 Report Share Posted November 17, 2022 Log MAP using ECU logging at 500Hz, I suspect you will find the occasional short spike in pressure which trips the limit. The limits are assessed at very high frequency, the statistics are updated slower so some very short events may be missed in the reported statistics. Note also with the MAP limit advanced mode turned off, the default limit control range is 10Kpa. This means if the MAP limit is set to 236Kpa, the limit will start cutting 10Kpa early - at 226Kpa.
