I've got a simple question, i think. I've switched my instrument panel from a grande punto 1.4 8V because the original one was broken. But when i connected it the new one (from a scrap yard), everything worked except for the speed meter. I went to the dealer charging me 80 euro's

So i heard that the speed meter could be working if i do a proxy alignment. My question is if this is true, if this is possible with the FES software and if it is possible with a ELM 327 1.5a cable.
Perhaps not that simple question, but maybe someone went down that road

So if anyone could help me, thanks in advance...
