T1N owners, I thank you for your participation in the other thread.

I've closed the other thread since the T1N owners have spoken.

This thread is specific to US/Canadian Diesel NCV3s:

If you've replaced or repositioned injectors in an OM642.993 (2007-2009 US/Canadian Sprinter) or an OM642.898 (2010+ US/Canadian Sprinter) AND in doing so, you skipped the injector reclassification procedure, what happened?

-Jon

PS: Here's the procedure

(This is from the Dodge 2007 Sprinter manual. I believe that T1Ns have a similar requirement.)

INJECTOR CLASSIFICATION PROCEDURE
NOTE: The engine must not be running for this procedure.

NOTE: If installing a new injector, make a note of the seven digit alphanumeric code. You will need to enter it into the scan tool during the Injector Quantity Adjustment procedure.

NOTE: Before performing this procedure, if the ECU has been replaced, or if any injector has been installed anywhere but its original location, make a note of the seven digit alphanumeric codes and the physical location of each injector. You will need to enter them into the scan tool during the Injector Quantity Adjustment procedure.

1. Turn ignition switch “ON”.

2. Using a scantool, select ECU View, then MISCELLANEOUS FUNCTIONS.

3. Select Injector Quantity Adjustment, then NEXT.

4. If the ECU was replaced, the Injector EEPROM Location procedure must be performed. Select YES, then NEXT, and follow the directions on the scan tool. Otherwise, go to step 5.

5. Select the injector(s) that has been replaced, access the keyboard function, and type the seven digit alphanumeric code next to the cylinder number that corresponds to the physical location where the injector has been installed.

6. Click NEXT. The scan tool will prompt to turn the ignition switch off for 12 seconds.

7. Repeat step 5 and 6 for any other injectors that are new, or have been moved from their original location. Once injectors are classified, cycle ignition to complete.

8. Once the seven digit alphanumeric codes for all injectors have been entered into the ECU, cycle ignition to complete the procedure.

I hope I am under warranty or Geert has the Carsoft working if this ever happens to me. Is it the same procedure or similar for T1N?

Apparently the documentation for T1Ns is the same, but in the real world, it's not necessary.

The T1Ners have spoken:

I really want to hear from someone that has replaced their NCV3 injectors w/o a dealership-class scantool.
