Need a working ECU preferably Bosch 052 but 037 should work.

@jimc

I have several tested ECU's. Will check for those numbers.

I think you mean that the 044 would also work. I have a spare O37 that was replaced on my '74 LE with a 043/044 (stock for North American '74 GA motors and 1974 through 1976 RoW GB motors). 037 ECUs were only used in '73 2.0L GA motors and were meant to be pared with a 037 MPS and I had a rebuilt '73 037 paired to a '74 043 MPS. A rebuilt 052 worked fine in my LE's 2.0L but I wanted the correct ECU.

Problem solving by substitution is not a cheap way to go. Another lesson learned.

Did you find one?

037 ECU was used on the '72 1.7 and both the 1.7 and 2.0 in '73

in '73 the 1.7 used the 049 MPS and the 2.0 used the 037 MPS

Yes I did.
