Coding is required when changing and installing new fuel injectiors on your BMW. This can be done with the use of the INPA software.

A video guide created by Johnny's Speed Shop shows a step-by-step guide on how to change BMW fuel injectors and code them with INPA. Check it out in the video below:

Coding your BMW is highly recommended when changing to new fuel injectors so that the engine can run properly. Each fuel injector is designed with varying power and flow rates. If you won't code your new injectors, your vehicle may not be able to recognize the variations in fuel flow correctly. Your vehicle may end up either burning too much gas or getting not enough gas.
