ECU part numbers for 1975 L-Jet, looking for info Options

[rick_cv]

Trying to piece together an L-Jet fuel injection system with the parts I currently have. Missing the ECU and have a 6 pin AFM. Does anybody know what the correct ECU part number is for a 6 pin AFM? The early 1974 411 has part number 022906021F and the going rate is 1/3 the price of a 1975 914 unit, part number 022906021G. A 1975 bus ECU typical part number is 022906021H. These are all indicated for manual trans but not sure which AFM they work with. Thanks

clay perrine knows a huge amount of detail when it comes to these components.
he will occasionally go into it. (IMG:style_emoticons/default/biggrin.gif)

what we have been able to find out is that even though they list the AFM for 74s as the one part #, when you rip them apart inside they were even modifying that on the run from early ones to later ones. particularly how they were building in the temp sensor.
its the first year of L jets on anything and the VW version is basically the prototype.
its not on anything else anywhere else in the world except the USA.

the ECU on the 412 L jet could have been mapped differently.
its an automatic exclusively. no manual gearbox.
so thats my hesitation in saying its exactly the same - despite the CARB documents.
