BMW N54 Injector Replacement & Coding | ECS DIY

[@sixwayback]

Best video Ive seen on this. Simple, quick and informative

[@JuicyN54]

I didn’t need the inverse e10 bit. I needed an e10 socket

[@scawthorn13]

Do you have to replace 3 index 12 injectors? I thought you can’t mix 12s with anything lower than index 9

What if I already have a cabin air filter delete? I’m asking since the cowl delete kit comes with the new cabin air filter and I don’t want 2 more of those. What can I do/buy that can help me with that?

[@drs214tx]

Is it the same for N55? If not is there a vid for that?

[@racecarcamp9056]

It's very similar to do the hardware portion, but the injector coding is a bit different. Similar with the numbers on the sides of the injectors, but a different process.

Anyone else experience the Vehicle’s VO not being found/ read?

[@246alfa]

Engine N53, where is the fill check on the bench? BMW is the easiest car to check and remove injectors.

What happens if don’t put numbers into ecu?

[@e90jack]

It will not perform as ideally as it could. They are batch numbers used to identify the proper flow capacity of each injector and relay that info to the dme

[@repairvehicle]

@@e90jackhow does ecu know what batch of injectors has better flow or same flow?

[@racecarcamp9056]

@@repairvehicle You do that with the coding. The numbers on the injectors that you put into the coding software recalibrates the ECU to the those flow rates. Not coding them would risk running lean and grenading an engine - although I have never tried ha ha

[@repairvehicle]

@@racecarcamp9056 injectors cannot be recalibrated, it’s either open or close in simple terms it’s an electro mechanical valve. Computer send signals to open or close that’s it that how injectors work always worked. Injectors not any different than relay, open and closed. How do you calibrate relay?

@@repairvehicle sorry mate one word off - recalibrates the "ECU" to the to those flow rates. Good call out, edited the comment.
