    Question on timing about 10-15 seconds after startup

    Hey everyone,

    Novice here. Doing my first 24x 411 SBC conversion however not new to hp tuners.

    Car starts up and RPM goes about where I Would expect then jumps up a few hundred rpm then settles where its supposed to.

    From the log file it looks like after startup the timing is very low around 10-12* then it goes up to my idle timing (20ish) at that 10-15 second mark which is what causes the rpm to jump then it settles back down.
    Cam is 212/218 so might not need that much idle timing after all but just figured I would start there and could work backwards if needed.

    Thanks,
