So, the wonky ECU could be "good" ...for the right engine, not for a 3.2.
Dave... Is the chip below the one you refer to that should be replaced:

Yes, that chip controls the fuel & timing maps! It designed for a different 911 3.2 market/application, NOT for the U.S.
A post up-thread provides the correct Porsche U.S. chip. Again, it's a 10 minute effort to change the chip, and then the DME ECM becomes a stock 1987 U.S. Porsche DME ECM.
