    Mine appears to be different than your latency table. This one is for corvette with large cap.
    The table you are using looks like my old one. My engine is basically a stock 84 corvette L83 5.7l.
    Got this from 3rd Gen.

    800 214
    1200 275
    1600 305
    2000 244
    2400 275
    2800 244
    3200 305
    3600 320
    4000 290
    4400 305
    4800 305
    5200 305
    5600 305
    6000 305

    p.s. My ecm is 7747 not the original. It came with a chip for a '87 van w/o large cap.

    I looked at some of the post on 3rd gen and there seems to be different large cap HEI latency tables for different vehicles. I am thinking of getting a WB and try and do a better job of adjusting my WOT.

    I finally got around to installing a WB and mad some changes to the PE afr vs rpm and PE spark advance vs rpm, my WB seems to be reading about 12.9 to 13 under wot and throttle response is seems much better.
