Hi, first of all you friend should check if the ECU is Eu3 or not cos it's possible that tose who fitted the black top injectors changed or remapped the ECU for Eu2 too otherwise that engine should have been quite smoky under load as those injectors were overfuelled with Eu3 fuel map
as about coding, you should find out yourself if it has this function for Td5 or not, sems that it has it but they dont say for which engines cos for the Td5 the icarsoft is very limited
