So I'm just getting started with this whole open ecu tuning stuff. It's been several months of reading and searching online, also watching any tuning tutorials on youtube that i could find. I decided to try and tack a hack at setting up my ecu to log boost with the omni 4 bar and my afr with my wideband. I think i successfully accomplised that but in the process i made a mistake. I accidentally put the wire from the w/b to pin 77 instead of pin 75. Pin 77 is for fuel tank temp sensor curcuit. Im getting code p0183 for fuel tank sensor high input. I swapped the wires around once i realized what i had done and now I'm still getting the code on start up. I'm not sure where to go from here.

Reset the ECU by pulling your negative terminal and wait like 5 minutes.

Is that the same as clearing the code with evo scan? Also should i disconnect both positive and negative cables and touch them together like you use to have to do in the older cars?

Disconnected pos and neg battery cables. Didn't touch them together. I just let them sit there. The code was gone after i reconnected the battery cables. I start the car up amd just a couple seconds later the code comes back.

No it's different. I would not do that. Just keep it disconnected for a bit and give it a try.

I did as you suggested. It didn't seem to make a difference. The code still came back. I then reverted back to the rom version i had without the omni map sensor and also reinstalled the stock map sensor. Cleared the code, started the car idled a couple seconds and the code came back just as before.

I went one step further and I disconnected my w\b from the ecu and plugged back in the original wire. Reflashed the ecu to my last know good running rom version and ended with the same result. I hope i didn't fry something in the ECU by connecting my w/b to the wrong pin.
