Injection advance adjustment

If the values indicated in the table do not correspond to the detected
ones, follow the operations as written below:
1) Delayed Injection Advance: remove the shims under the pump un-
til the detected value corresponds to the one indicated in the Table
"Conversion for establishing advance"
2) Advanced Injection Advance: add shims under the pump until
the detected value corresponds to the one indicated in the Table
"Conversion for establishing advance".
Note: By removing or adding a 0.1 mm shim under the pump, it is
possible to advance or delay the injection by about 1°.
