Когда то отвечал на вопрос по замене форсунок, но конкретно инфы под руками не было:
Сообщение от DPBY
 Так просто форсунки не меняют. На форсунках есть инфа которую надо внести в память ECM при замене

А недавно случайно в сервис мануале наткнулся, вот:
Injector Adjustment Value Registration BBS002HV
DESCRIPTION
Injector adjustment value indicates manufacturing tolerance and the value is printed on the top of fuel injector.
The injector adjustment value which is correctly stored in ECM is needed for precise fuel injection control.
A performance of emission control and a drivability may effect when there is a mismatch between the following
two values.
The injector adjustment value stored in ECM
The injector adjustment value of the injector which is installed on the vehicle
Injector Adjustment Value Registration must be performed after the following cases.
Injector(s) are replaced.
ECM is replaced.
For the first case, Injector Adjustment Value Registration for the replaced fuel injector must be performed. And
for the second case, Injector Adjustment Value Registration for all the fuel injectors must be performed.
OPERATION PROCEDURE
NOTE:
Before performing this procedure, record injector adjustment value printed on a fuel injector.
When all fuel injectors are replaced or ECM is replaced, it is recommended to perform “INJ ADJ
VAL CLR” in “WORK SUPPORT” mode before performing this procedure. By performing “INJ ADJ
VAL CLR” in “WORK SUPPORT” mode, injector adjustment value stored in ECM is initialized.
1. Turn ignition switch ON (engine stopped).
2. Select “ENTER INJECTOR CALIB DATA” in “WORK SUPPORT” mode with CONSULT-II.
3. Touch “START”.
NOTE:
When touching “START”, CONSULT-II reads injector adjustment values stored in ECM.
4. Select the number of the cylinder which needs Injector Adjustment Value Registration.
5. Input injector adjustment value, and touch “ENTER”.
NOTE:
Input injector adjustment value is stored in CONSULT-II.
6. Repeat step 4 - 5 till there is no cylinder which needs Injector Adjustment Value Registration, and touch
“START”.
NOTE:
When touching “START”, injector adjustment values stored in CONSULT-II are written onto ECM memory.
7. After “CMND FINISHED” is displayed, make sure that the following values are same for each cylinder.
Injector adjustment value which is printed on a fuel injector.
Injector adjustment value which is displayed on CONSULT-II screen.
NOTE:
In this step, CONSULT-II reads injector adjustment values stored in ECM and displays the values on
the CONSULT-II screen. This is for checking if injector adjustment values are written onto ECM memory
correctly.

Владельцы бензиновых хитрил не безуспешно борются с большим расходом топлива чисками и "обучениями" датчиков и заслонок. Решил просмотреть, что есть в сервис мануале в этом отношении для дизеля. Оказывается на дизеле то же много чего надо "учить" : MAF, Fuel pump value, форсунки и т.д. Но всё это критично только при замене самих мозгов (ECM) или заменяемых узлов. Но так же встретилась фраза:
" If the battery is disconnected, the emission-related diagnostic information will be lost within 24 hours.
The following data are cleared when the ECM memory is erased.
– Diagnostic trouble codes
– Freeze frame data
–
Fuel pump learning value
Actual work procedures are explained using a DTC as an example. Be careful so that not only the DTC, but all
of the data listed above, are cleared from the ECM memory during work procedures."
Так получается если АКБ была отключена более суток значение
Fuel pump learning value сбрасывается и возможно нужно "учить" заново???
