i have searched please help

hi guys
my disco td5 needs the injectors programmed as i have recently changed the engine & kept the original ecu
it does run but i have been advised to code the injectors
i have found someone local with a nanocom that can do it for me but he is not sure how to do it
i have done a lot of research & am aware that i need to retreive codes from injectors & enter them in the nanocom - then send to ecu
my questions are as follows
which cylinder is number 1 - front or back ?
does anyone know of a how to explaining how this is done ?
i have searched this forum for info & also searched you tube but im struggling to find definate instructions
can anyone help with any advice or is the nanaocom so simple to use that i wont need instructions ?
really hoping someone can help me with some advice as he is coming to do it this evening
many thanks in advance

Hi, Nr.1 is in front of engine, with nanocom in Td5 engine - Settings - Injectors you'll have to write each code and save, that's all ...the menu is human friendly, once there you'll figure out

excellent - cheers sierrafery
