richardpalinkas Posted November 24, 2018 Share Posted November 24, 2018 What offers more engine braking? More ignition timing or retarded timing on decel? Dfco enabled or disabled? Thanks Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted November 24, 2018 Share Posted November 24, 2018 DFCO enabled means no fuel so it will be the maximum engine braking possible. When DFCO has not kicked in less timing will cause more engine braking as less timing means less torque. You can also try playing with cam timing (more vacuum means more friction) and reducing dashpot airflow will also increase vacuum. Experiment and see.

richardpalinkas Posted November 24, 2018 Author Share Posted November 24, 2018 Thanks Roland. Ive been playing with retarded timing, -10 deg under decel, which seems to offer good engine braking without too much pops and bangs, just some burble in the exhaust. I will see what a combination of dfco enabled will do also Quote Link to comment Share on other sites More sharing options...
