Duratec (2.0 AODA) Completely new to ECU master

GENERAL
1

Hello everyone!

I’m completely new to ECU programming and ECUs in general. My background is in STM32 and Arduino projects, so I’m comfortable with wiring and figuring out sensors. However, I’m trying to understand how much of the general guides and “how-to’s” I find online actually apply to my specific engine.

The main challenge is that I can’t seem to find much information about my engine, so I’m unsure what exactly I should be looking for or focusing on.

From what I understand, these are the basic inputs an ECU needs to run an engine (please correct me if I’m wrong):

  • TPS (Throttle Position Sensor)

  • Intake temperature / pressure / airflow (I plan to use a MAP sensor)

  • Crank sensor (I believe mine is a 54-tooth wheel)

  • Camshaft position sensor

  • Wideband O2 sensor (I’ve ordered a Bosch 4.2)

  • Speed sensor

  • Injectors out

I also believe the car uses a CAN bus system, but I currently have no real understanding of how that works something I plan to learn over time.

My main goal right now is simply to get the engine to start and run reliably.

If anyone is willing to point me in the right direction or share some advice, I’d really appreciate it!

Thanks in advance, and apologies for my English it’s not my native language.

You might need a bit more than that.

I believe those have variable valve timing so you’ll have 2 cam signals and 2 outputs to actuate your cam timing.

Its either waste spark or COP ignition so you’ll need 2 or 4 ignition outputs.

fuel pump relay output

rad fan outputs

coolant temp sensor

I am probably missing something but I cant think of it off the top of my head.

Thank you for replying,

These engines don’t have VCT, i noted coolant temperature and these engines have the coils on top of the bougie. They have 3 wires (12+ , common , signal)

For the fuel relay i will look it up where it is. :flexed_biceps:
