Re: Injector coding on Punto 1.3

Hi,
The IMA code of the injector describes precicely its characteristics. The manufacturing process cannot guarantee that each injector will function exactly the same way as per specification. At the end of the production line each injector is tested by a test equipment which measures its chracteristics and generates the 9-digit IMA code which is then stamped on the injector.
The ECU uses this info to adjust precicely the injection time for each injector so that it injects the correct amount of fuel in the cylinder.
Yes, it is possible to enter a close value for the injector (by changing one of the digits).
And, yes, it is possible for the ECU to reject the injector code. Based on the IMA code the program in the ECU estimates that the characteristics of this particular injector are not good and it is not suitable for proper operation.
