To start off, I know that gobs of black smoke is wasteful, gives diesels a bad rap, and possibly harmful to the engine. I don't often do this, but I like to pull up beside cars with fart cannons on them and give them some diesel smoke to choke on.
So onto my question, is it posible to fool the ecu into seeing the 25 psi of boost or whatever the max is before the engine goes into defuel mode, without actually making that much boost? My guess on how to do this is to alter the signal seen by the ecu from the map sensor. If so what does it take to do this? I seen one person that did it to their common rail cummins and it would fog the streets endlessly. I know what over fueling does to diesel engines, I just wanted some input on how to do this.
