    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    Default Question on Cleaning up idle!!

    Just wondering about cleaning up my idle and best way about doing it.

    Rafig is close. Problem is car still has a lope and rough idle even with a 224/228 cam.

    What is the best way to reduce fuel waste @ idle other than injector tables or is this the only solution?

    It's going to sound like it has a cam in it even with a 224/228. My friend's 224/224 cam had a nice choppy cam sound to it.

    What's your desired idle rpm set at?

    How much timing are you commanding in the base spark in gear table at idle?

    What does your AFR look like (either WBO2 or fuel trims)?

    Idle is set @ 875.
    Timing in Gear starts @ 27* @ starts to drop @ 40 grams/cyl

    I have been in SD for some time but did go CL for a day and car was adding fuel. That kind of threw me but thought it might have something to do with my altering DFCO.

    Car has red top 30# injectors with IFR's adjusted. Just wondering if the 30# injectors might still be commanded to much fuel even at the lower rpm.

    I'm battling my SVO 30's too. I'm finding that I'm having to alter the offset (voltage vs manvac) table because there's no other way to get the min pulse width down. I've tried skyrocketing the IFR table, dropping the VE table, dropping the min. commanded pulse widths, etc. with no luck. If I figure it out, I'll post up.

    As for your timing, you've got too much. I'll shoot you back my timing tables when I get a minute this week. They should be a decent starting point for you. You may have to reduce 'em a little though with your CR being 11.5. If you did the RAFIG process and it's close, the idle shouldn't be too bad. Sent PM...
