Hi guys. I was very lucky that I bought a g35 version of the rev up with 300+ km mileage and invested a lot of money in it, however, one of the previous owners, of which there were a lot, changed the engine management software (something like a chip tuning) and now it's hard for me to set up the auto when I return the auto to stock. Tell me where can I get the original program?

 

Do you know exactly what software was used?

The most common is the UpRev software, you will need a cable to be able to access it to see if there's already a license on the ECM.

@seymore4 can answer your questions.

 

maybe I'm not expressing myself correctly, I need the original engine software control, chip tuning just kills the engine
I think if someone has a car with the same engine, we will have the same firmware, just a copy is enough

 

Go to the dealership

 

Yeah in order to flash the ECM you need to use the dealership Consult-II or III tool, you don't download software for it there are specific modules it uses for various vehicles.

As Seymore suggested, a 1 hour diagnostic at the dealership is your best bet.
