    Конечно, каждый раз перезагружал За ещё полез в гугл, наткнулся на такой пост из адврайдер Pin 87 Grounded: Tells the Motronic that a catalytic converter is installed. Those maps are designed to arrive at an Air Fuel Ratio of 14.7:1 in the cruising range. Pin 87 Ungrounded: On the R1100 if this pin is NOT grounded, the Motronic would look for a CO potentiometer. Since the CO specification is 1.0 to 2.0%, which implies an AFR between 13.8 and 14.1, and this fueling map is designed to arrive at an AFR of 14.0:1 with the co pot adjusted and at small throttle angles.. On the R1150ungrounding pins 87 and 87a on my R1150RT produced a somewhat leaner AFR than with both grounded but the bike still operates in closed loop. Pin 86: On the R1100, if this pin is grounded, it tells the Motronic that lower octane fuel, lower power is expected, and/or the motorcycle was shipped to Switzerland. In the US on the R1150GS, this pin is grounded for models allowing lower octane fuel. I don't know what's special about Switzerland but I'm guessing that Pin 86 is a signal to retard timing compared to other maps. Pin 87a: This pin is grounded or not, depending on which type of intake tube, valve cam and cylinder head is installed. Pin 87a R1100 models: Grounded for intake tubes 137 1134 1405/1406 (longer and narrower); cams 1560--on the R1100R andR1100GS. It is ungrounded for models R1100S, R1100RS, R1100RTwhich use the shorter, larger diameter tubes. Pin 87a R1150 models: Ungrounded for intakes tubes 1405/1406, etc.--R1150R, R1150GS and R1150GSA. It is grounded for modelsR1150RS, R1150RT (with the shorter fatter intake tubes). Pin 87a Fueling Effect: My guess is that the longer narrower tubes have a lower Volumetric Efficiency and need less fuel at some points in the fueling map. Therefore if you signal that fat tubes are installed (ungrounded 87a on the 1100s or grounded on the 1150s), and then install the long narrow tubes, you will get a richer mixture in parts of the fueling map but the process of closed loop mixture adaptation mostly negates this. И все стало ясно: отключением пина 87 я сделал смесь богаче, а вот 87а тут не к месту, т.к. патрубки короткие. В моём случае для более бодрой езды достаточно вынуть перемычки совсем. Вопрос в том, как после такой езды будет чувствать себя катализатор.
