    why are you running 4 degrees at idle?

    so, just for testing.... put the idle advance at 12 degrees and zero out the vacuum


    advance for now..





    ignition timing:



    idle rpm 950

    total rpm @ 2100

    total advance @ 34

    vacuum advance @ zero



    lets see if the motor likes this





    been working with a customer with the same combo





    Engine 408 Chrysler (stroked 360)

    Cam 507 lift 237 duration intake

    502 lift 241 duration exhaust

    Set to Performance cam

    A/F Targets:

    Idle 13.5

    Cruise 14.0

    WOT 12.8



    Idle RPM 800

    Total 2500

    Idle advance 16.0

    Total advance 32

    Vacuum advance 8

    Pimp squirt 25%

    Power valve enrich 20%

    Question, are the idle timing and total advance equal all in timing? Thought I saw somewhere that the idle and total timing equal the advance. In my case based on your recommendation 12* at idle and 34* total advance would put me at 46*? Or is idle not included in total advance?

    Total timing is initial timing + the difference to get to the 32*. The system will not allow it to be over the setting you entered. Since the tech said try 12* initial the system will add a max of 20* timing. Vac advance is on top of that so they said to put 0* so you should see 32* max. I believe I read this on their FAQ plus I talked to a tech one time about it.

    OK, that makes sense, thanks. Out of curiosity, what changes in the system when you select performance camshaft versus mild camshaft?

    I left tom's on mild. Seem to do the trick.

    Made suggested changes, car ran good on throttle, but did have a lot of detonation on top end. Still fighting the surging and eradic timing at idle. When stopped timing would go to 9.5* and even drop to 6*, not even close to the 12* I put in to the system. Think I am done, just too frustrating, ordered my FiTech EFI today, heard a lot of good things about the system and not so many good things about the Atomic.
