    Default SD Step by Step

    Well, I have the commercial version up and running and would like to go SD over the weekend. Virtually all the online advice I've been able to collect refers to the older, copy the high to low spark table method. I could certainly use some advice from the more experienced members here, as I'm new to tuning and plan to move slowly and carefully. I do not yet have widebands installed, so BEN tuning will have to wait. I plan to completely remove the MAF, as IAT is a separate unit on my car. Thanks in advance.

    My advice, wait until you have a wideband; the BEN "AutoVE" process is worth it.

    I'm sure that's the quickest route to success, but I'd like to become comfortable with the "old fashioned" way as well, just in case I was stuck on a desert island with a toasted WB. I suspect there will be a number of folks at my same point on the learning curve who are going to be content with NB tuning. There are some decent SD tutorials out there right now. Is the method the same here, except skip the part about copying high octane to low octane spark tables?

    In SD mode, you need to copy the high oct to the low oct map.

    On my PC I have a nice little how-to document that I wrote on SD tuning. Challenges with sharing that today:

    1. I'm 400 miles away.
    2. The beer tastes mighty good.

    Even with the modified O/S that allows dual spark maps in SD?

    If this works as planned, I'll send you some of your favorite brew. I had a forced retirement from drinking, and can only enjoy it vicariously, a la "The Big Sleep"

    Happy Holiday!

    No, if using them then to tune each table just force the octane scaler to either 0% or 100% as it will run dual spark always.

    1. Do you still have this to share with everyone??
    and
    2. Is it for all years or only pre-2001's that you need to copy the high oct. to the low oct.??
