Is there a way to protect eprom 95080 from writing?

**brchip** · 14th February, 2014, 06:41 PM

Hello,

I have a ME7.9.9 ECU from Astra 2010 and I removed the immo from dump. It worked fine a few hours, then it coded (the client said he removed the immo box from car!) again and I confirmed that the eprom dump had been changed.

Is there a way to prevent writing so the ECU won't update this eprom or maybe a better immo off solution?

The ori and immo off dumps are attached.

Yes it is possible .You have to set 0x8C to status register and after that to pull down WP (write protect) to ground.
