Thread: SD Card Tuning versus Handheld Tuning...Problems, Issues, Advice, Tips?

  1. #11


    I took a look at your file and it's not one anything in a street car will run off of. You have 32° of timing almost everywhere, and then 41° at 1400, and 50° above 1400. Here's a screen shot of the Base Timing Table I did today for the Super Victor intake swap I just finished. Take a look at what I've done for my combo and look at what yours looks like. Let me know what you think and I'll help you with the tuneup. It has a conservative timing curve and added timing at cruise. Not the best screen shot, hope it helps. Jimmy

    MODIFIED GOOD TUNE is the one made from laptop, which will not run the car.
    Look at your Ignition/Magnetic "Filtering" ("Low" as opposed to "High") & "Inductive Delay" (140 usec as opposed to 160 usec).
    May God's grace bless you in the Lord Jesus Christ.
