Thread: New to dodge tuning and trying to find out the basic steps

  1. #1

    New to dodge tuning and trying to find out the basic steps

    I have been reading and reading on this forum and its really hard to pull all the useful info (That relates to almost stock setups) out of the threads since most of the threads either start with blown or cammed motors or end up there anyway. So what I am looking for is how to tweek the tune to get the 20-25 hp and the responsiveness that the predator tune gives you. I have a wide band o2 installed and configured into scanner but Im not sure where to go from here.

    06 charger srt8
    CAI
    180 T STAT
    Aftermarket TB and i cant remember stats on it
    I run open exhaust most of the time via cutouts

    I know this is likely to be boring to all you advanced tuning guys but any pointers or links to threads would be greatly appreciated.
    Thank you

    5.7 vs 6.2/6.4 VVT
    https://forum.hptuners.com/showthrea...-6-2-cam/page2

    An FCA workbook that describes how VVT (VCT) works. Basically when the OCV is 0% PWM the cam is in lock pin (full intake advance) and when it is at 100% it is full intake retard.

    Nice article where 3 different cams with identical lift but different LSA.

    VVT explained by Hot Rod, the graph near the end hits home as to why VVT is beneficial.
    https://www.hotrod.com/articles/hrdp...-valve-timing/

    VVT tuning from The Tuning School which apparently shows some gain in tweaking VVT on what I guess is a stock motor. As for their dodge tuning course book, VVT is really not discussed in detail.

    You will need to set-up the VCM scanner charts/channels to match the tables (base spark, injector pulswidth, power enrichment...) you intend to tune in VCM editor. If you youtube search the tuningschool, they have examples of how to do this.

    Here is one example.

    The real credit goes to those that generated all these useful posts. I got tired of using bookmarks for all the links and decided to make a post so I could have all the info in one bookmark. I usually add links to my original post. In fact, just added a thread on throttle lag that popped up on the forum recently.
