Opel Astra H 150hp with Quaife LSD

[biela]

Hello

Car is an Opel Astra H 1.9 cdti with 150 hp and EDC16C9 ECU.
My brother has installed a Quaife LSD in the gearbox.

But standard ABS/ASR unit is programmed to brake the wheel that lost traction up to 30 km/h.

I´d like to change this setting to 80 Km/h, like Alfa Ducati Corse with Q2.

Is there a way changing the attached ECU bin to achieve that?

Or do i need to read/modify/write Opel Astra H ABS/ASR unit?

Thanks
