Checked yesterday and the timing is pretty rough, and it looks to be sitting around 5degrees at start and then slowly climbs to around 20 as a apply throttle and the motor warms up. Does this need to be adjusted in the tune or by moving the distributor?
I had this response from one of the guys on thirdgen forums:
Are you able to either drop the other spark tables in or adjust these on my tune LRT? :) :) :)Timing table you are looking at 34-36 deg at wot, 36-38 cruise areas, and 25-26 ish idle. In 411, the table is based on grams airflow per cycle or so. A na motor typically sees .80 or so gram/cycle. I would have to double check my logs but the max value of 1.2 i hit at 3-4 psi boost by 3600-3800 rpm so i think na motors see .80-.90 and not much more. I'll confirm that later
In general stock ls1 timingtable could be used but add 3-4 deg to it in the higher rpm higher flow areas as a ls1 sees best power around 26-28 deg while a sbc typically is 34-36. Ls1 cruisetimingcould be used. Idle areas may need increased due to larger cam
