Good Afternoon Guys.


I have problem with turning off speed sensor in MS41.
To be honest I'm just beginner in remap, but trying on my own car (test car).

Maybe I will fast describe issue:
Car have faulty ABS sensor and engine was unable to go higher than 5500rpm during driving and on beginning on idle.
RPM was rised to 7200rpm by one of my friends, and then on neutral gear rpm gauge go to the end .
However still during driving, rpm don't do higher than 5500.
Of course before I ask for help, I was trying to find ecu definition for RomRider or TunerPro, but nothing was compatible with hw.

Does anyone can help me to turn off speed sensor so rpm will go to max during driving?
(Engine speed limiter VSS error)


HW: 1429861
SW: 4101
VIN nr.: WBADD31020BU41572

7488 HARD LIMITER - you want your engine blown ? m52 should not go past 7k RPM , if you want your OIL PUMP to be alive , also m52 engines have slow hardlimiter because of bolts on oil pump can unscrew itself .

Here is vss on 7k and hardlimiter like in m3 .

thx and rep if working 



ps: use partial flash if you want to work on this ecu , fullflash isnt necessary .

Thank you very much (rep+thx added).

This car is totally scrap buyed just for fun for less than 300e , so if engine blow rest of wreck go to scrapyard. 
And thx for tip, next time I will read partial (kess was read full, but all definition for RR working only for partials).

Just for you know , kess read isnt good for MSXX ecus , better use normal K-Dcan cable and Flashers for them , MS41 QuickFlash for MS41 and MS4X Dev Flasher for MS42 and MS43
