Injector code calibration problems

[Rodders 1]

Hi Guys,
I have a Mk 7 Transit 2.4 RWD 08. I have recently fitted a set of second hand injectors to see if I could get the van running. It starts and runs sounds like one of the injectors is U/S as sounds like a tractor at times. My problem came when I was putting the new codes in to Forscan all injectors except No 2 were excepted.
On the number 2 injector it came up with an error code saying something like, it was out of calibration limits and to re check the code. I have checked the code on the top of the Denso injector many times so I know I have entered it correctly. Any thoughts?

If they are second hand then they will be out of the spec of the original c2i code anyway as the injectors wear over time. The ECU learns the characteristics of the injectors when they are in use so with luck the ECU will self adjust. You can also do a pilot injector learn in ForScan and that help smooth the running as long as it can carry out the procedure. Any problems with the pump or injectors and it wont succeed.

What Grogan said.....second hand injectors can be false economy....best to get properly reconditioned items which should come with new calibration codes or just get new injectors.

PF Jones can supply the right gear.
