reading and writing 206 gti

Hello, since my Peugeot 206 gti 2003 136cv has the ecu in the picture, that I could not read in any way with tools original the other, I deduced that you have to desolder. Since I don't want to touch the ecu to keep it as a replacement voucher in the event of future damage to the undersigned, do you think I can find a controller that compatible for? you can read it via serial? Since I've seen the same car mount units, which are read quietly I think it's possible, thanks to all.
