Hi guys,

Does anyone knows what is the chip eprom number for Opel Corsa B 1,6 16V engine X16XE?
ECU - GM DELCO 16163479 BHPZ
I'll appreciate your help.

Thanks in advance

On the original chip I can not see any numbers which can help me how to read it.

I can't tell you for sure.. but i have an GM Corsa 1.6L 8v (country: Venezuela). And it uses a 27C256 EPROM. It's a 28 pin IC. Yours might be using a 27c256 or 27c512 probably the same as mine though..
