    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...
