I need help with an immobilizer code I am getting. U1451 is the code. I have everything wired up for my DOHC 4.6 Fox swap. The computer flashes fine, using an SCT X3 handheld. The engine starts right up no problem, but then immediately dies. I talked to the guy that sent me the tune and he assured me that the PATS was turned off. He is a reputable guy in this area. He told me the "U" codes were body codes not engine codes. What I assume is happening is the computer is looking for all the extra crap that came in the Mark VIII like SCIL module or the message center stuff that uses the OBDII bus wiring. I have been told that can be flashed out but my guy didn't know anything about it. Please help! Can I spoof out what it is looking for? or tune it out? Has anyone had this issue? Thanks!
