Transponders
 

Does the transponder have to be a amb260? 160? or an amb? cheers

Pretty sure they ask for it to be a AMB 260
It may suprise you but your 583 could possibly cross a timing loop on a circuit above 160kmh but I doubt if you will be going faster than 260kmh

Thanks, i didnt know what th 160/260 was now i am enlightened. 260 all the way cheers:D
