That information pointed me in the right direction. But then got confusing. ECM Guy wrote:

Well if I add 0xF4 0x57 0x01 0x00 I get a checksum of 0x4C? So that does not correspond to the 0xB4 So I added the 0xFF and got Ox4B? went down? did all this using a calculator. The looked at the Command entry/Edit box in Tunerpro and used the checksum and came out with the same thing... then tried the Checksum box with ones complement and got OxB3 but forgot to add the $FF from above and then got the correct Checksum that was there in the first place 0xB4.

So conclusion when building an ADX from ALDL is use info from ALDL.ds for that Mode 1 data message
ALDL.ds says: MODE 1 (TRANSMIT FIXED DATA STREAM MESSAGE 0)
ALDL REQUEST:
- MESSAGE ID = $F4
- MESSAGE LENGTH = $57
- MODE NUMBER = $01
- MESSAGE NUMBER = $00
- CHECKSUM

TP Mode 1 Message 0 send says "0xF4 0x57 0x01 0x00" Click the Checksum box and choose 2's complement and you will get the 0XFF added to it plus incoming message for the correct Checksum of 0xB4 for that message. Copy it and add it to hex stream.
0xF4 0x57 0x01 0x00
and paste 0xB4 to get.
0xF4 0x57 0x01 0x00 0xB4

$B4 or 0XB4 is 180 in decimal. I still have not figured out exactly what is uses to get that number, but at this point TunerPro has another built in feature to serve this purpose!

Then if you have the correct hex string 0xF4 0x57 0x01 0x00 0xB4 you can use the Checksum button to check, it should come back as 0x00 in Sum. 0x00 in 1's Compliment and 0xFF in 2's Complement.
