Hi,
I want to remove the speed limiter on a 2009 Citroën Jumper 2.2 HDi.
ECU is Visteon DCU-102 SW: 96 664 843 80 (6C1U-12A650-ER)

I already have:
• Full ECU file read
• Access to BSI
• Diagbox available

I can see the speed limiter parameter 90km/h in both ECU and BSI using Diagbox, but it’s factory-locked and can’t be modified.
Does anyone know what exactly needs to be changed in the ECU file or which parameter needs to be altered in BSI to disable the limiter?

Thanks.

Looks like speed limit in DCU file is 255, you need to set it in BSI
