td5 injectors

Hi all i,ve read up on how to set up mechanical clearance of rockers to injectors but with regards to the setting up of the electrical side do i have to have the injectors re-programmed at landrover dealer or is it time i brought a Hawk eye /nanocom ,will nanocoms not do this.? I have just put a new rockershaft in and also noticed that three injctors have blue tops and two injectors have black ,does this relate to anyhing!!!

You do need to program the injectors to the ecu. The injectors should all be the same colour and have the same part number. it is not recomended that you mix colours, Their are 3 types black for early engines, blue i think is early, and green is late type 15p engines.

black is the orignal injectors but the blue ones are replacements it is my under standing that black and blue are interchangable but green is not interchangable with anything
and yes you can use nanocom to program injectors
