i need help with tuning a ghost cam Sierra 4.8

[Mr.AT]

Hello,

yesterday i tried to do a ghost cam on Sierra 4.8L 2006.
with 2 tables only
Spark - Advance - idle adaptive spark
Overspeed & Undersppd tables

i did rise the values in both of them and the car idle nice with a good sound for cam and everything seems normal.
but i got check engine " Random misfire code " after few min. and it's not stable ( check engine light flashing )
the check engine disappear every few min and it get back.

Can someone tell me if im missing something here. Is there a tables which need to be adjust?

thank you in advance

You are missing intelligence. ghost cams are bad tunes made worse. Just don't

Could you please explain more why you said that?

This is a single cam non VVT…..

the application may be modified to run within the confines of specified/specific parameters reliably or sufficient to drive the vehicle,

whereas the practical application of tuning an engine and it's software component is towards minimizing carbon coatings and partially reacted combustion chamber byproducts

in other words, efficiency and reliability as well as minimizing maintenance costs and resulting end user wear and tear is partially responsible to(depends on) ideal combustion dynamics given the supplied hardware and details within the software, if there even is software. (Engines can run without computer control and be tuned well, or not, similarly)
