Hi Guys,
I wonder if any of you CAT boffins on here could shed light on this fuel saving idea.
Recently I carried out an experiment on one of our CAT 785 trucks (old type 3512 engine Africa) regarding methods of fuel saving by setting down the "air fuel ratio" on the engine ECM, this I did by setting it down one value (which equals -25 on the ET screen) then I took down ECM hours and monitored it for a week and then set it back again to the normal parameter. During this experiment we had no overheating or power loss and no operator complaints.I found by doing this we burnt 5 gallons (22.5 liters) of fuel less per hour. Across our fleet this could be a massive saving but would wish to know that before carrying such a procedure what would the long term effects be?
Look forward to your comments.
Pete.

ok you were able to set the air setting down, and how did you get the pass words, to change the setting? You can't normally change settings in an ecm controlled engine.
