Hi guys - looking around what is the maximal value of KFPED map ?
in my current maps is set to 39322,0000 - however one point is set bit higher 39324,0000
Is there way of calculating the max - or just believe that full open throttle is on 39322,0000 ?

Kfped is throttle % torque map. Axis are RPM and throttle % output is torque max 100%.. If you have 39324 then something is wrong |

"Maximum" is not what you think it is. |

Strange - as map looks ok - is ME7.3.1 - Alfa Romeo 2.0 TS with selespeed gearbox - thats what is DAMOS showing  |

Good hint  32768 but it mean that Alfa Romeo Engineers set map for pedal request way to high  So or is there correction (need to take a look on map props) or ..... have no clue |

The actual defined maps should have these factors in them to make the scales and map values 'real' world for humans. IE make sense in terms or rpm/%/map |

So question why full damos don't have the proper factors  - been checking other related maps to KFPED but no corresponding values range found... Try to understand section MDFAW: x-axis y-axis KFPED WPED_W NMOT_W KF accelerator pedal characteristic How should I understand this: The pedal characteristic is stored in the map KFPED. From accelerator pedal position and engine speed, a factor (relative torque request) in the range of 0 to 2 is generated (mrped w). 0 is corresponding to the request of the minimal indicated torque, while 1 is corresponding to the request of the maximal indicated torque. Values between 0 and 1 lead to a linear interpolation. The setting signal of the cruise control is also a relative torque request (mrfgr w) that becomes important if it is higher than mrped w. In this case, B fgr is set |

so given two points, (0, 2) and (0, 2^15), what is offset/slope? |

OK - spend 2 days of thinking and still no clue - maybe as i'm not English native so maybe I'm losing some context... So is there any straight forward answer what is max value in this case ? Just keep in mind that the values I have show are original so I can believe that factory want to give full power on pedal to the metal - or maybe I'm wrong and some power(torque) is hidden behind ? Other changes been done to the maps - like some ignition advance etc... so theory is more (torque) generated - question if this additional one is not blocked by pedal torque request ? |

It took some time  but I just get it The magic number offset factor is ................ 0,0030517 So max requested in KFPED is 120% ..................... and now the question WHY is more than 100% ? and other question - which other important maps use this factor  ? |

Stop posting your spam and do some reading.
You have no idea what you are doing and adjusting that map is not going to give you any more power.

0xffff * 0.0030517 is not 120%
