Hi, i have a alfa 147 cluster with nec processor, 780826 serie, maybe someone try to change miles through obd port or maybe this isue come after they remove the positive pole of battery, i don,t know, the fact is that now it display only ------ , i try to repair it with tachopro 2008 , cause it is the only tool which can support this processor, it read all ok, but it can,t write the km in it, every time it show an error, i,ve read some forums and some blogs, but no one has a solution, maybe with this thread we can find something, i have upa usb by elrasoft too, but it can,t read cause it support 780828 and above , i have a clone FVDI too, but when i try to change km through obd it give me no connection with the device, but if i enter under cluster list, i can read 1046848, something like that, more than a 1 million km, anyone any idea how to resolve this isue ? thanks
