I have a couple of these hanging around and I’m not sure if they are all interchangeable or not?
I thought there were some differences between the different systems (1.7 vs 2.0) but wanted to ask. As of now everything is carefully associated with the complete system that was part of. Thanks! |

No, not interchangeable.
For 914 2.0L's there are two different MPS's, and their PNs end in 037 (1973-only), and 043 (1974-76). These are physically the same internally but are calibrated differently for compatibility with their respective ECU's, which are also different. The 914 1.7L has a single MPS, PN ending in 049. It is physically different internally and calibrated differently, from the 2.0L MPS's for compatibility with the 1.7L ECU's. |

QUOTE(JeffBowlsby @ Dec 27 2018, 07:42 AM)  No, not interchangeable. Jeff, how do us guys with 1911 motors deal with the 049 MPS issue? I have an Innovate LM-2 AFR meter, so that should help with the adjustment? (IMG:style_emoticons/default/confused24.gif) For 914 2.0L's there are two different MPS's, and their PNs end in 037 (1973-only), and 043 (1974-76).

It is physically different internally and calibrated differently, from the 2.0L MPS's for compatibility with the 1.7L ECU's. I plan to keep the 1.7L FI components but use green 2.0L injectors. I also have a set of 1.8L injectors, but think the 2.0L will be closer than those. |
