I AM TRYING TO ADJUST MININUM SPARK BUT I DON'T SEE SPARK RAMP OUT...ON MY FILE IT JUST HAS BASE,LONG TERM,REDUCED POWER AND DOUBLE PULSE UNDER MININUM SPARK TABLE.DOES ANYONE KNOW WHICH TABLE NEEDS TO BE ADJUSTED TO KEEP MY TRUCK FROM GOING TO NEGATIVE TIMING WHILE IDLING?
I HAVE A 2016 SILVERADO 5.3 W/ GPI STAGE 2 CAM..IT IS SHOWING NEGATIVE TIMING WHILE IDLING..:banghead:
That's typically a issue with the VVE not being tune and the next step would be torque model. Changing the limiters to spark isn't really the way to go.
Well i am just going about this all wrong then..
This may be helpful to you...Go to tuning101.com>play lists>genV and watch all his Gen V videos.
