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%
