    Default WOT AFR & Timing Tuning

    I kind of started this topic in the thread about getting my LC1 working, but want a thread dedicated to WOT AFR and timing tuning. Hopefully this thread will end up usedful to other newbies like the idle thread.

    This run was mad on 93 octane fuel, from where I always buy it. There was no audible pinging at all. For those that haven't been following, I've already completed the CalcVE tune on my Main VE table and MAF table.

    I'm most concerned with getting rid of the KR. Where do I start?



    Looks like my WOT AFRs above 4,000 RPMs go from 12.30 to 12.86, getting richer as the RPMs climb. Isn't that on the safe side of a good tune, and can therefore be eliminate from being a cause of KR?

    How about getting rid of that KR? How much KR does it take to hurt an engine? I know I'll be tuning it out, but just curious. Each WOT run in this log was different. One had nearly no KR, another maxed at 4, and then the last about 6. Is there a map you guys use to tune out KR?

    Is the Spart High-Octane Table the one I'll be using to adjust WOT spark timing in order to reduce KR? What's the Base Spark in Gear table for?

    Lots of questions. Take your pick
