I checked the part numbers on my EFI components against the table on Paul Anders website and discovered that my 73 has 74 EFI components. Specifically my ECU is 039-906-021 (Bosch 0-280-000-044) and my MPS is 0-280-100-043.
Can anyone tell me what this means for performance? I've heard that the 043 MPS doesn't provide WOT enrichment. Is that true? If so, can it be recalibrated to provide better WOT performance? Also, is it worth adding a resistor to the CHT lead? |

As you can guess, the systems are a set of matched components. the components are calibrated to work with each other. Mixing them...all bets are off. No doubt they will work ok to some degree, but they will not be optimal. Because you are restoring this FI system Bill, the best advice is to get everything correct. So...you have a 73 car? Be sure you have all 73 components.
So get a 73 ECU and find that resistor... |
