Spark timing

[chevydan]

Hello all. I have 1 quick question. I am running a 3bar cos3 on my rr I need to know what tables to adjust so i have absolutely no timing when i go into boost. I am a noob to tuning so dont hurt me to bad.

Hi CD, welcome to the forum

A0010 = boost timing table

A0010 description says:
"Once the MAP is above the maximum value allowed in {B0101} "Main VE Table", the PCM will subtract this amount of timing from the final spark advance."

So whatever timing results from B5913/B5914 (and modifier tables), A0010 then subtracts timing from that.

Ok so in the tables b5913 it is in rpm and grams per cyl. And for the boost timing A0010 table is in map kpa. So my question is how do i know how much to put in the A0010 tables looking at the B5913 tables ?

Look at the last columb in B5913 (1.20 grams/cylinder)

The values you put in the Boost timing table will be subtracted from there.

so if you are in a cell with 24* timing and you put a value of 10 in the boost timing table across the board you will only see 14* when in boost.

Thank you much.
