"The 'LH' stands for German: "Luftmasse-Hitzdraht"" -- https://en.wikipedia.org/wiki/Jetronic

The 510 is not specific to the heated oxygen sensor. It is the one that will work in place of 503. IPD circulated the rumor that LH2.1 exists more widely than it does. Both 83 and 84 non-turbo use LH2.0 which then was called LH-II. The EFI 84 turbo used in a 7-series has adopted the LH2.1 spot before LH2.2 came out for the 240 in '85. Dave -- blame IPD for the disinformation.
