This Atap reading ok for a cam?
This Atap reading ok for a cam? only got to make one pass, but usually all of my recordings are about the same so
02's were .88-.90 at 100% WOT
LTRims were 17 to 18 at WOT so am i running lean?
Timing was 21-22 at WOT.. LOW???
KR was none
ideas and opinons on how to tune these numbers??
I mult the MAF table by 105 to get my part throttle LTRIMS to average +12(still lean)
if i need more timing please explain how to edit that with edit

Re: This Atap reading ok for a cam? HD: you are running pretty lean. What were your LTrims before the cam? Do you have port MAF ends?
If your part throttle LTRims(exclude 0% TPS readings) are consistently +12% then multiply the table by 13% (113).

if i mult by 115% will that lean my 02's out or richen them up some?
i cant figure why my timing is low?
oh and yes i have ported MAF ends. Im thinking about just putting the stocker back in without screen to level things out a little bit?? Good idea?

Re: This Atap reading ok for a cam? You can leave your ported ends on; this helps explain why you are lean and why you need to correct for it.
Yes, using 115% will richen you up. It tells the PCM that for a given MAF frequency, you are now flowing 15% more air, so the computer will add the extra fuel needed.
