I was told the 74 and 75 L-jet for a 1.8 motor is different. I was wondering what exactly were the differences, and can you see them just at a glance. If anybody would like to post a picture please do... (IMG:style_emoticons/default/popcorn[1].gif)

If anybody would like to post a picture please do... (IMG:style_emoticons/default/popcorn[1].gif) '75 and '76 L-jets were different from the earlier years. The major difference was the additional pin on the airflow meter -- early meters had 6 pins and later meters had 7 pins. Of course, the changes aren't limited to the meter -- the wiring harness and the ECU were both changed to support the different meter. So you can't just swap out 1 component; you've got to do all 3 for a backdate or update. I've run my '74 engine with a -76 L-jet system. Just had to swap out the meter, wiring harness, and ECU. |
