    Sorry, I just needed to look at TP to see what you meant. see next post.

    After some more coffee I will try and read that again...


    To add to your info, from TunerPro Help:
    Data Source Size - This specifies the number of bits (and bytes) that will be used to
    calculate the displayed value. 8 bits equals 1 byte, and 16 bytes equals 2 bytes
    (MSB, LSB), and 32 bits is 4 bytes (MMSB, MSB, LSB LLSB).

    LSB First - Specifies the byte order
    of the source data. If checked, the source data is treated as
    least-significant-byte first. For instance, if the following byte sequence were
    streamed, in this order to the port: [11, 28], if this parameter is checked, the
    number that the stream represents is 2811. If this parameter is not checked, the
    order converts to 1128.

    Operation - In
    this group of parameters, you define how the bitmask will be resolved into
    either TRUE or FALSE. This resolution is done via bitwise operators. You can use
    bitwise AND or bitwise XOR. Below is a description of these operations. You may
    have to read it a couple of times and examine the examples closely.

    Description

    Example (binary)

    Data
    Operation
    Operand

    Result
    Bitwise AND
    If the bit in the corresponding position of the data and the
    operand are both 1, then the corresponding bit position in the result will be 1.
    Otherwise, the corresponding bit position in the result will be 0.

    AND
    11110000

    11100000
    Bitwise XOR
    If the bit in the operand is 1, the corresponding bit position
    in the result will be the opposite of the position's bit in the data. If the bit
    in the operand is 0, the data's bit is unchanged.
    11101101
    XOR
    11110000

    But cut and paste is about all I can do when I wake up...

    OK so looking through the '7427 hac, it looks like you just set the value to display from packet 34 for the TCC PWM, and set it to 16 bit, and NOT LSB first. If you click "LSB First" it will read them 'backwards'. Then it will look at both 8 bit values and treat them as a 16 bit. I just had to look at TP to see what you were talking about. There are quite a few values that come through as 16 bit.

    Yes I got that part.

    I was looking through the 427 $OD and $OE trans stuff adx since $OD is supposed to be for 4L60E and a lot is simalar... but math does not add up right in equations, so I may not have a grasp on this yet. I'd like to learn how to do it by what ALDL.ds says then just copy from similar parameter. They say same thing as mine above for those values but the way you describe math equation is not same or it's probably my math skills and not having a full understanding of it yet... notice I said yet...

    I would think if the ADX is set to treat them as a 16 bit value, then the math becomes much simpler, just multiply or divide by conversion factor. But if you were to set them up as two ADX values, linked, then the math gets a little more complex.

    Eaglemark, please don't use my stuff as an example of good math. My math skills suck! Most of the equations used came from other definitions of from the hack, these are most likely correct. But with the equations I had to come up with on my own, those are very hit and miss, especially with the 16 bit ones. You'll notice that several of the 16 bit xdf addresses just display hex.

    Well then, we had better keep talking with Greg cuz he comes up with these equations pretty easy! Maybe he can add a "Math Needed" needed for TunerPro equations writeup when he has time.

    I know I have another post like on previous page explaining how to get correct hex address from ALDL into TP coming...
