Double-posting because it's JUST THAT IMPORTANT.
Erase what you wrote there. My ECU works just fine.
You know what it was? The CABLE. When I first tested the new adapter, I used this setup:
Laptop-->USB Cable-->USB2Serial-->Box-->Car
When I went out there just now, I used this setup:
Laptop-->USB2Serial-->Serial Cable-->Box-->Car
The ECU returned proper data. When queried with 78123400, it returned 123400123400123400123400123400123400... I was shocked by how uniform the data was, so I ran Kevin's tool.
My ECU ID is: 722525. Comes up each and every time. Kevin's tool also runs properly and loads the values you put in there. I have noticed that as it scans, it occasionally receives null values (gauges return to zero), then suddenly will pick up the values again and display them normally. Does this happen with your 94 as well? Is it just Kevin's software? The Com Tool doesn't experience any delay with the ECU...
So yeah! Oh and I promised dumps from the ECU and TCU, so here you go... they're attached...
Oh man... I have such a huge stupid grin on my face... wow...
