I've got some general setup tips for a timing map courtesy of scott avoy. I'll dig it up then edit the post with it.
EDIT:I'm leaving out some of the information as to why you'd run specific timing values, but here is scott's "bible" on setting up timing. If you want his reasoning too, let me know.
Timing basically levels off over 3500rpm, like this. These are values for 0 BOOST:500 RPM - 20 deg 1000 - 20 1500 - 22 2000 - 25 2500 - 27 3000 - 30 3500 - 32 4000 - 32 4500 - 32 . . . 7500 - 32
For full vacuum (and below 3500rpm):500 RPM - 20 deg 1000 - 20 1500 - 24 2000 - 28 2500 - 32 3000 - 36 3500 - 40 4000 - 40 4500 - 40 . . 6500 - 40 7000 - 36 7500 - 34
In between 0 vacuum and full vacuum, just do a nice slope between the values above.
For boost, retared by .75deg/psi off of the 0 psi numbers. Here are some check values:For 14.7psi of boost:500 RPM - 9 deg 1000 - 9 1500 - 11 2000 - 14 2500 - 16 3000 - 19 3500 - 21 4000 - 21 4500 - 21 . . . 7500 - 21
REMEMBER: all of these numbers are degrees of timing. I'm not sure how the PFC timing maps work, I know for my AEM I just put in these numbers and that's that. For the PFC you may have to change the numbers based off of what the base timing is.
