Thread: Timing Question

  1. #1

    Default Timing Question

    I finally installed the Holley Dual Sync distributor and everything is up & running. The truck runs better now than it ever has before, but I noticed it takes a little longer to start after the Dual Sync installation. Before the swap, I had timing set around 6° BTDC and it started immediately. Now, with timing set at 15° BTDC it takes a little more cranking before starting; it doesn't crank long, but there is a difference. Can I adjust my timing closer to 6° in the handheld without having to adjust the distributor too? Also, I've noticed guys increasing their cruise & WOT timing from the set parameters in the handheld. My truck is just a regular old daily driver, no street/strip driving. Is there any need for me to change the cruise & WOT timing as others have done?

    So use the 6° Cranking Timing that worked well.

    Yes. Once the ignition timing is synchronized, all timing changes are performed on the 3.5" TSLCD or laptop EFI software.

    Also, I've noticed guys increasing their cruise & WOT timing from the set parameters in the handheld.

    I would have no idea about your engine's timing advance needs.
    May God's grace bless you in the Lord Jesus Christ.
