Hi, I have a 2016 CX 3 1.5td and would like to know how to recalibrate the injectors please? I will be changing the oil and filter at the weekend and resetting the ECU oil data using forscan.
I have tried searching Google for the process but can't find the specific instructions for my cx3.

Thought I'd try bumping this because nobody has answered yet.

I want to recalibrate them because I believe that they are letting excess fuel in during a regen which is making the oil level rise quickly and way above the x mark, I'm doing an oil and filter change every thousand miles or so which is excessive! I have a 7 mile commute to work and often it's still doing a regen, is there a way to cut the number of regens at all? How can I find out if the pcm needs a software update?

I think you can calibrate using an OBD2 scanner and FORScan software. I would ask in the FORScan.org forums, e.g. https://forscan.org/forum/viewtopic.php?t=6381
but you may have leaking injector seals or some other issue.
A dealer will be able to tell you if there's an applicable PCM update for your car.
Regular trips of only 7 miles is not good for modern diesel engines and the DPF.

I have recalibrated the injectors on our Mazda 2 1.5D using Forscan and it made no difference to regen frequencency. On average it regens every 150 miles and this lasts for about 10 min. I record the mileage and the number of regens using Forscan.mr_chris79 wrote: ↑Sat Jun 04, 2022 9:15 pm I want to recalibrate them because I believe that they are letting excess fuel in during a regen which is making the oil level rise quickly and way above the x mark, I'm doing an oil and filter change every thousand miles or so which is excessive!

Sadly, your commute is too short. By the time the engine has got up to temperature and the regen starts, there is no time for it to complete. Then this cycle starts again when you drive home and you are in a constant loop of failed regens and rising oil levels. These diesels need at least one 30 minute journey weekly.
It sounds like a petrol car would make more sense for your requirements. Failing that it might be worth getting the injectors checked by a diesel specialist as they can suffer from cavitation and poor spray patterns. Good luck.
