I doubt this is the case but...

Code 51 is also related to the A/C system which you've removed from the vehicle. If errant currant is entering the A/C signal line to the ECU this too can cause a code 51. The solution here is to ground the A/C signal line to the ECU. (sorry I don't recall specifically which line it is though)
