Injector Coding Required?

[windskipper]

Hi
I just changed no2 injector on my Mk6 Gold with a recon injector. I have 4 cylinders again! Hooray
How important is the coding of the new injector? Seems to be running OK but I don't have any software or leads.
I'll book it in for 5 mins somewhere if the coding is super important. Just begrudge overpaying someone to type a few letters onto a keyboard (I m from Yorkshire!) hehe

It is very important for proper fueling . It must be done.

Most likely if you dont code it, Youll get imbalance faults for that cylinder.

I have a junkyard injector in #3 and have swapped ecus with immo deletes. I don’t get any codes. Do what you wish in regards to coding but my CJAA runs runs just fine otherwise.

Since installing the tune I have a wider imbalance between all 4 cylendars, but the spread of all 4 zero out (average) each other. Is that normal? Would you say the closer the better the better the power/mpg or not enough to matter.
