My brain seems to be toast, and I'm looking at buying a spare known good one to swap in to test out this theory. I have a 74 1.8L with L-Jet; can I use a '75 brain? Are there any important differences between the 2 years?
Thanks. |

The differences in the L-Jet systems were all in the air flow meter and the wiring harness. The "brains" are identical.
In 74, they used a common wire for both the AFM and Air Temp sensor that is co-located in the AFM assembly. In 75, they split out the wiring, separating the AFM and Temp sensor. Seems there was some feedback issues with the common wire. I have never seen one of these "brains" fail, its usually something else causing it. |
