Marine Engines:
3412C (S/N: 3JK1-UP)
New software is available for the 3412C PEEC III engines. The new software provides a larger field adjustment range for the reprogramming of the "FLS" setting when the ECM is replaced. The larger field adjustment range will compensate for normal variations of factory FLS settings. The previous engine software did not index properly or read the correct speed and load values. The values that were displayed on the Engine Vision histograms were zero. The new software will now read and display the correct values for each histogram on Engine Vision. Personality modules can then be purchased from the Parts Distribution Center.
