Throttle valve 1 calibration: not completed

[maxninet]

2017 - R ninet

all attempts to "Reset the adaptation values for the throttle twistgrip sensor" are unsuccessful.

Additionally the "Throttle valve 1 calibration: not completed"

the value for channel 1 & 2 upper adaptation is 77% and the value for channel 1 & 2 lower adaptation is 19%

are these signs of a bad TPS?

[botus]

have you got any further with this ?

I suggest till TV1 completes it will never move to TV2

on the other tool there is user interaction required to complete this procedure....  has on screen instructions - hold it open on full throttle for x time then slowly roll off the throttle, then OK, then key on off etc. for it to save settings

it doesn't go to 100% on most bikes - because its all about fiddling noise and fuel emissions - but can be well worth completing - I once got my k16 back and it was utterly gutless - either the dealer after a software update forgot to do it (likely) or these days deliberately set it slow (becoming normal dealer fun) it only gave 70% throttle - after I calibrated using tools at home it opened to 89% throttle and power output was transformed

UPDATE

it was not possible to calibrate the throttle with the GS-911 or the TEXA scan tool.

However, the BMW dealer was able to calibrate and save the setting with OEM tool.
value was around 80%

all attempts to "Reset the adaptation values for the throttle twistgrip sensor" are unsuccessful.

not sure why I never mentioned previously - there is a TIPS document for wires never clipped into the multiplug housing on the wires to the twist grip - affected loads of different BM modules basically they forgot to make the looms with enough care and some pins are falling out so never connect up fully when the two sections go together

SITUATION
When diagnosing fault codes below, technicians erroneously condemn the electronic throttle grip, which analyses show is rarely the culprit.
0x3A13D7 throttle grip sensor, short circuit to ground (duct 1)
0x3A13D9 throttle grip sensor, short circuit to ground (duct 2)
When either or both of these faults are triggered, the vehicle goes into emergency operation and a fault message appears in the instrument cluster.
These faults are often sporadic or not permanent and a faulty plug connection can often cause this condition.

PROCEDURE
When diagnosing the cause of these fault codes, perform a guided diagnosis with ISTA.
During the guided diagnosis, one of the steps is checking the plug connection S177*1B to the electronic throttle; this plug connection should be examined closely.

the above is not applicable to cable actuated throttle like 2017 R nineT.

its only for later ride by wire models

[botus]

yes - of course
