Typical 5.7 injecter duty cycle percentage at idle?

[Tyree]

I am trying to learn tunerproRT and compare my own log files against log files from known good running engines. Can anybody direct me to a log file for early 90's or late 80's 5.7....... I am also wondering what would be a typical duty cycle for a 5.7 tbi at idle. Also what does Spark Advance from Hack* mean?

After reviewing my own log file, I observe that my injector duty cyle is alway over 100 percent? This does not seem right to me.
Any help on this would greatly be appreciated.
Thanks -Tyree

Without knowing your ECM or BCC, it is kind of a guess, but the "hack" they are talking about is a patch to the bin to display spark advance in tunerpro. Same thing with injectore duty cycle. No patch, no worky.

Jim. I am using a 1227747 ecm stock for a 5.7 engine.. The bin is not modified. I am on learning curve trying to see what is normal and what is not.
Thanks for your reply.
