    Default Normal Vs Performance

    Can someone please confirm for me what the computer is seeing as performance? Is it WOT or what?

    In what context...?

    No, it is not related to with WOT.

    Some PCMs/calibrations have two sets of tables: one set for Normal, and another set for Performance/Tow/Haul.

    Is this related to FlashScan V4 software...?

    Well depending on what tables I'm tuning sometimes I just have normal and performance, and some have normal,performance,and tow/haul. All on the same vehicle. Don't really matter that much cause I just make em all the same but I was just curious when the PCM sees "performance"

    There would be a switch on the dash/console.

    Any particular reason for posting in the V4 aka OBD-I section of the forum...?

    Other than being new to these forums... No lol hummers have a t/c 2 button that allows for a little extra slippage but when I'm doing a burn out or spinning at the beginning of a race I def don't want any breaks being applied by ABS. I guess I'll just leave the ABS fuse out till Somone can tell me another way

    Studer, if you have a T/H mode button then when that is on, the Performance shift tables are active. Otherwise the PCM uses the Normal pattern.

    So if you want full out race shift points, set them up in the Performance tables. Drive around town normally, when you want to race hit T/H.

    I understand...

    Posting in the right section will ensure that forum members with the same PCM see your questions...

    [ for example, a V4 software user will not have answers for V7/V8 questions ]

    The T/C button is different than the T/H button.

    Like Erik said, if you don't have a T/H button then the PCM uses the Normal tables.

    Yeah it seemed that simple at first to me at first too and then I started seeing tables where it had all three pentameters (normal,performance,tow/haul) so that threw me off. Even my friend Joe that's been tuning for years was confused when he saw that.
