Well here is one thing I did that may help. Mines would not run right either, I put carb back on but removed the ECU from the fitech, mounted in car and kept all the input sensors like 02 sensor, temp, vac, TPS, intake temp. Now I can data log carb, look at data, and change jets or step up springs as needed. Works great!
Spent to much money to just get rid of it. Even if the ECU dies the car still runs. I changed the 60psi in tank pump to a 12psi. Plumb in regulator, return line was already ran. I actually like this set up better.
It's been a while, so I would need to try and find it again, but I found the information by searching. FiTech or someone associated with them wrote the code for the program so hard to believe they wouldn't know the error code, its literally in the software code. That's how software code works, it doesn't just generate some random error code with no meaning. Let me see if I can find it again.
It's been a rough battle. I know my engine wasn't in the best of health, but I rebuilt it over the summer and broke it in with a Holley carb. Then put the FiTech back on and just really couldn't get it were I thought it should be. So for now, it sits in its box on a shelf and I put a Holley carb back on and it runs great.
Buick Grand National for almost 30 years with aftermarket systems such as fast so I'm quite familiar with tuning so forth and so on however , decided to just take it back stock with a refresh.

Interesting use of the FiTech for sure!

Fitech doesnt even know what code 105 is. How do you know it is something to do with the o2 sensor?

Getting ready for an install, so im chewing on every vid.
Hows it running now?
