    Something WEIRD with the SA. I've never seen the SA max out like the "johns after i drove it.xdl" The WEIRD SA shows up in the history tables. The BLM's need tuning.

    edit
    Ok, I looked at the .bin file, it looks like to me the SA table is WAY WRONG!

    kinda thought I had too much in there but it doesnt seem like it driving it and the plugs actually look decent but thats what I thought just dont know why its taking so much timing to get it to run but the only thing im not certain of is if the timing mark on the balancer is right... normally when I build a motors I degree and mark the balancer for true tdc but I didnt build this motor it is a crate motor somone else put in

    Even if you take out the 20 bias the spark table is crazy? But max spark in bin set to 34? Base timing at 1? Log shows your in ALDL mode? Hitting 96 degrees advance? Unless your doing something with your XDF and ADX this is firing 2 cylinders off? How do BLMs look good?

    This might be a good time to test JeepsandGuns new XDF and ADX...
