peugeot 205 1.9 gti ecu
I have recently purchased a second hand chipped ecu for my pug 205 gti,it came of the same model as mine no abs or cat ect. all the serial numbers match, but im worried to change it over as i dont no enougth about ecus, if i unplug my original ecu to try the chipped one will it reset it or not work when i put it bk on? it is 2 bolts and a plug, is it as easy as it looks or is there more to it, like programing or just straight swap?
