@StarBear & @wonkipop want to hear from members who own 1974 1.8s.
to assist with a topic in originality section of the website. Cars need to be reasonably original with L jet fuel injection system intact. If you have the time and can help us with some information it would be great. information. 1. Vin Date - month and year (no need to post vin numbers if you don't want to). thats the date on the driver door sticker. 2. Karmann plate #. or if you have already done the maths, the day and week of the year the car began production. 3. Image of engine bay emission sticker (lhs above the air cleaner - white with red letters). sticker should say whether it is an EC-A or an EC-B engine and whether it is california + EPA or only EPA. 4. image of engine tune up sticker. this is the small white sticker that is on LHS engine tin just below fan shroud. most of them are gone by now, but some engines still have them. 5. image of the throttle body. image of the distributor. we are looking at the vacuum hose set up between the distributor and the throttle body. ----- (IMG:style_emoticons/default/beerchug.gif) |

Getting more data; eventually we WILL find a correlating factor or spec. Key question is : How are EC-A and EC-B engine equipment or setups different. “Should” be more than just the mileage/drivability setup issues. Then, that whole engine tin numbers issue. No consistency to establish a pattern. (IMG:style_emoticons/default/confused24.gif) |

No consistency to establish a pattern. (IMG:style_emoticons/default/confused24.gif) the factory manual describes only the EC-B set up. talks about disconnecting both vacuum hoses for idle set - doing the timing at idle. no mention of the single hose set up or descriptions of a vacuum hose going nowhere off distributor, or advance hose not being connected. one thing to keep in mind. these are L Jet numero uno. they likely were playing around as they went with different kinds of fine tuning of this set up. that double vac distributor had interesting possibilities when you think about it. it had plenty of capacity in built for mechanical advance in terms of "performance" behaviour. but playing around with how you activated the vacuum advance had big pluses for meeting emissions and doing other stuff. and maybe some big minuses too. the L jet on the 412s is set up completely differently at the same time. its running EGR in 1974. VW are really experimented with L jet doing lots of different things. far as i know 412s also ran the EC code engine. but whether it was an EC-A or B or something else i don't know. never seen a 412 emission sticker to know. |
