Omni 4 bar and aem wideband logging
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.

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.
