So.... you want your car to sound like you have a set of cams without any performance increase.

TLDR: All it's doing is tricking the car into dumping excess fuel, adjusting the timing and the lift electronically to simulate the cam lope. The crap they spew about low down torque and stuff is just a marketing ploy to get you into the bama tune and your friends probably believe it @steve99 can probably elaborate he's well versed with this stuff

No problem and I edited it with some less nsfw language, personally I've edited my tune specifically so it's quieter on idle because of this exhaust and steve helped me check my work. The easiest way to do anything yourself would be get an OFT and romraider. Also if I had an extra 5-10 grand when I was choosing this car I would've totally sprung for a coyote powered stang maybe even waited a year for one with the IRS, bama tune and exhaust really livens the coyote up alot. It's way easier to make power on those cars for cheaper than our cars that's for sure

Ok , im not a tuner :-)
AFAIK the vvt cam phasers on our engines are inactive at idle ie they sit at zero offset. This is probably in the ecu code and probably because their is insuffient oil pressure to drive the actuators reliably. I am not familiar with the coyote engines or ghost camms, but i would suspect they have deliberatly set up the cam phasing at idle\rest position to produce the lumpy idle. This would not be possible in our engine unless you physically adjusted the idle\rest cam phasing, which is then going to throw out the rest of the phasing ie you have to account for the offset you physically put in at idle, how you would achieve the physical offset would be another problem unless you reground cams or just jumped a tooth on the timing chains. I doubt you could achive the lumpy idle effect without that , ie just with fueling or timing, and their is a heap of tables that adjust idle parameters, and probably a lot of ecu logic that not known in the idle area. even then its never going to sound like a V8 :-) |

With ecutek you can do ghost cam easily
With custom maps, you overrides the 0 at idle and put like 19 or 20 to both cams and it will start the lumpy idle that is for saying... that you seem like quite a enthusiast... you should think about upgrading to ecutek with racerom access Last edited by tomm.brz; 11-13-2019 at 04:03 AM. |

Contact a guy called @aagun on this firum he has coded the ghost cam effect on non ecutek roms, he will likey want a donation though for his work

Lower the idle to about 400RPM. It'll run rough and sound like it's having a hard time keeping itself idling. Ghostcam.jpg

also it would lower the oil pressure too much, it won t even activate properly the vvt best and quickest way to ghost cam is with ecutek, and actually rise the idle to at least 950rpm to have it sound good prepare also to consume a good 30% more fuel during idle |

@Rezi
you asked me how to get it in ecutek i took a stock map as example, if you want ghost cam in Map 4 you do something like this: there is a little bug that after the engine is started and you enable it, only exhhaust cam go to retarded value but then you just have to touch the throttle even minimally and also the intake cam will advance and creates more overlap also raise idle to at least 900-950 and play with idle timings if necessary do this by yourself, i won't take any responsability |
