This link does not contain much that pertains to stock Vanagon ECUs. The
historical and technical inaccuracies make me wonder if it was written
by a student.

As early as 1967 VW sold cars in North America that had ECUs controlling
electronic fuel injectors.They sold lots of them. VW Vans did not get
fuel injection until 1974, for the 75 model year.
