How to make a ghost cam tune in coyote engines using SCT software.

Which tables that will effect the overlap from cams to make a ghost cam sound?

I know it is through Variable Cam but there is a lot of tables inside VCT.

Ia it under those two tables Optimal power EX valve closing point and OP Intake valve opening point.

>> weighting factors
definition of exhaust closing MP set the bottom 0 point to 10
definition of intake opening MP set the bottom 0 point to -40

>> variable cam
mapped points to fuel economy distance add 10 at the bottom to point 0. You'll have to copy 13 to 0 and paste at 14 so it move everything up to give you that free spot down low.
max exhaust cam phasing set it to 50 around idle rpm
max intake cam phasing set it to -50 around idle rpm

>> idle
set min mph for idle to 0
rpm error from desired to begin idle 350
rpm error from desired to not allow learning 300

>> OBDII > Misfire Monitor
engine rpm to turn misfire test on after bg and set it above idle rpm
do the same for the min rpm to perform background misfire test scalar as well

Be mindful that ghost cam tunes often have valve failures

Ok that's what I am looking for. I will try it after 1 week and let you know how things going on.

Thank you Decipha :)

Decipha, What about shooting flames/Backfire out exhaust.
Is it by reducing the ignition spark timing to (-10) or something like that at low rpm / low load in the table ?

no, in order to shoot flames out the back you have to kill ignition so unburnt fuel goes in to the exhaust then ignites on the way out when it hits fresh oxygen. Will probably blow up the mufflers if it has any.

I cant think of any reason why you would want to do that or cant think of how to do it without causing some nasth aide affects.
