lol, mainly just curious on how come my 60hp tune doesn’t do it but others do. Didn’t know if it was an sft thing or what.
to understand this, you have to understand what causes the black smoke. Black smoke is caused by partially/unburned fuel. this incomplete combustion comes from a lot of fuel getting dumped in to the cylinder with an inadequate supply of air.
your 60hp tune does not smoke because they tuner is not a goofball. They are commanding the correct amount of fuel for the airflow and rpm.
SO... if you want to roll coal, you have to tell your tuner to screw up the tune and command too much fuel.
Be warned though - when you roll coal you are doing a number of things that are not good.
1) Pollution - im not a greenie, but i appreciate the efficiency and power of a diesel.
2) High EGTs - you are beating on your turbine and exhaust valves.
3) law enforcement scrutiny - you will get noticed depending onwhere you are. If you find a greenie cop, they will ticket you.
