    main spark table question

    hey guys

    well i got my HP tuners a lil bit ago and just started to really get into it. right now im working on my 2004 tahoe, im working on the main spark advance table

    i went through the repository and looked at a couple 4.8 tunes with modified spark tables and noticed that the more cylinder air mass- the less advance in all the tables, i thought it would be the other way around

    thanks guys

    The more air the less spark you need, it is a quicker burn.

    That's a very good fundamental to have a clear understanding of! I'm sure I will be able to help myself with that one.
