Hello,

need help with this MEMS MKC101960 1185 4040 ECU, from a ROVER 220 COUPE TURBO 200HP 1997.

I want to do Stage1. I desoldered chip AT27C246R 20JI and readed ori file (see attached)
This chip cant be programmed so I bougth AT27C256R 70JU and writed Stage1 file. (see atached)

Now car doesnt start. Car starter turning but wont start.

What I am doing bad? The file os OK? The chip is compatible?

Thanks.
