grams/cyl = ????
MAP is manifold pressure. That's the dynamite in
the shed.
Think of g/cyl as the amount of dynamite in the hole.
I think you will find it as cylinder air or dynamic
cylinder air.
g/cyl @ atmospheric goes directly to peak pre-
spark cylinder pressure, and this goes to burn
rate, hence it is the key spark advance index
along with RPM.
I don't remember about EFILiveV5 (why not V6?)
but if it doesn't have that PID available you can get
it by calculation, there are threads on here that
have the formula, I dug up this same thing the other
day but forget where now... something like
MAF(g/sec)/RPM*600
or similar. Seek and ye shall find.

just back to post that I found it and what you said is right, its CYLAIR is what I need to look at, I didnt have it being used yet so I'll try it later, thanks for your info... 
about the reason for v5, is I'm not 100% usto it yet so I dont want to have to start all over learning to use it again, I havent had any problems w/ it yet, so I'm in fear that it'll *** up just like everytime I update my computer, lol, btw.. how'z the hp tuner workin for ya?

Grams/cyl = MAF (Grams/sec) *15 / RPM
I think there is a calculated PID for this in EFILive V5. Or go to EFILive.com -> http://www.efilive.com/forum/viewforum.php?f=4 and ask for the PID. They're very helpful.
