@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) |

ok @L-Jet914
i have scanned through your stuff you posted. its all there --- exactly what i have found in the parts manual. the ECU is the same from the VW vans (kombis) and 412s. the AFM is the same. both do not change. universal. all that is different is the 914s run a different distributor. only the 914s run VR. vacuum retard distributors. but the vans and the 412s run EGR. you set them up different at idle in terms of idle revs. they all have the same CO. 4.5% max. its all in the distributor!? and of course how that must connect to the throttle body. and this is somehow being submitted in the first quarter of 1974 calendar year. ,,,,,, except i think we did find an EC-A that was built before calendar year 1974. have to trawl back through the info in this thread. i think its yours actually. 11/74? (EDIT - its nihil44's EC-A). but seems to imply an A comes after a B. they could have been making them in anticipation knowing they were ok and ready to go? if that is the reason they were knocking them out of germany in 11/73. be great if there were similar CARB/EPA documents out there covering the EC-B version. i bet they date from earlier than these documents? incredible find you have in your files.
