Uber-easy DIY USB ALDL Cable

[Barry Lyndon]

After doing some reading here and elsewhere, I bought this:
Attachment 15422
.. and it worked!
I just connected the Tx and Rx wires together and stuck them in the M pin, and the ground wire into the A pin.

Then after a slight learning curve with ALDLdroid and TunerPro RT, and some tinkering with various definition files that were quasi-related to my car, I finally found the right combination that gave me quality data.

For my 1993 Oldsmobile 98 (L27) with the 16141470 ECM, the $F5.adx is the one to use. I made a couple edits to the file so that the SEND commands would show up.
I have the factory service manual so I'm going to go through and edit the .adx file some more so that the values/units jive with the manual - just the plaintext and obvious stuff, not the hexadecimal code about which I'm clueless. Then I'll post it here so the one or two others who still drive '93s can use it in the future.

What I'm looking for is the .xdf file that fits my car as well as the $F5.adx does. I have the 5B4.xdf, but some of the data is nonsensical.
Anyone know where I can find that?

See what I'm really wanting to do here is diagnose my transmission. Either the torque converter clutch solenoid, or the TCC PWM solenoid, aren't behaving correctly.
According to what I've gathered so far, the TCC is operating at full line pressure pretty much all the time. I want to be able to open and close that solenoid from my laptop/phone to test it.
That's what the factory service manual is telling me to do as the next step in diagnostics -- but with a Tech 1 tool. I want TunerPro RT to be my Tech tool.

Hey guyz!
I have FT232RL cable. It works perfect with 8192. RX and TX are spliced to 8192 baud pin. And ground. Thats it.

I need to connect it to 160 baud car. Tons of information about it. It differs and no working solution found.
What modifications I need to do to make it work?
