Emission reduction uses etc and rpm to target a cell. 750 rpm and 1200 are both commanding 0. 1400 is commanding 1.25.
Your idle rpm should be around 900.
Emission reduction rpm was 600, 1000, 1500, (guessing those rpm but you'll understand). During idle and cold starts, rpm will be greater than 1000 rpm, causing a unstable idle, up and down, not ghost camming because over 1000 rpm, your table is interpolating with the cells in the 1500 rpm column.
It's all good I appreciate it.
Is there a tread that talks about this good kind of info but not looking for ghost cams?
Have definitely learned a good amount here though.
If I'm correct
IVO at -20* then has the Intake valve opening 20* after top dead center
IVO AT 20* has it opening 20* before top dead center? The Exhaust one I'm still a hair confused on.
How do yall test what's working better without dyno, just drive and see?
How do you even know where to make the changes anyways with the 26+ different map points with even just borderline, MBT, and even just the VCT.
thanks
-20 is advancing 20* BTDC
+20 is retarding 20* ATDC
The mapped points and the 26 sets of tables are all dependant on cam angles. You can log intake and exhaust cam and know which mapped point to adjust. But I suggest you use the "mapped point weight" and make a histogram of your borderline and MBT tables in the scanner for spark and knock Retard.
Hi there,
I have a question for witch I think there wasn't answer anywhere here in the thread.
If you make this ghost cam tune in a car that has cats installed - the only issue you get is damage of the cats, or some other damages can be done to engine due to higher temperature?
Thanks!
Im also having trouble how to figure how to ghost cam this mustang. I usually never stray from LS tuning, and im glad i usually dont haha, but can someone help me out? explain the parameters, its a 2020 5.0 with the 10r80
the cam tune just mimicks the valve overlap of old school big cams so no danger to the engine but you end up with lots of unburned fuel in the exhaust. Nobody ran cats back then so no issue but now with cats, which are designed to burn fuel in the exhaust, will be trying to burn all that extra fuel from the cam tune which Ford never intended.
guys, I don't have the Mustang anymore and have forgotten so much, I can't even fully understand my own posts from then. I can tell you that I learned a lot reading posts from guys like White5.0, murfie.
2019 C7 Stingray M7 - long tube headers, 6.30/6.22 226/238 cam, supporting stuff, DOD and VVT delete.
Stock everything else
thanks! that's what I thought. This tune makes no sense as long as you have cats in my opinion the sound is not also like the old cars
