VW LT speed limit remove / raise

[sparkymark8]

Hi Everyone,

Hope you are all well.

I need to remove speed limit on a VW LT 2.5TDI EDC15VM ECU. Eeprom is ST 24c04w. Can anyone help?

Currently limited to 90KM/H. Either remove or raise to 120KM/H.

Bosch 0281 012 135. Vag 074906018BL

Many thanks,

[VollPower]

Try raising the 0x5A value you have at position 0x68 in eeprom. Maybe you have luck.

No VMax in flash... edc15... no switch.
Its inside eeprom or if there is a tachograph, its inside there.

Tried 0x68 value, not better. Anyone any thoughts on EEPROM?
