I've somehow lost the post for the 40-toothed VSS tone-wheel that one of our members posted , and offered for sale . I'll need 2 of them , but can't seem to run the post down in Search . I'd like to mount one and spin it with the lathe to experiment with on the bench , and just see what kind of signal I can feed to this 16197427 ; the second wheel gets mounted on the transmission. I'm getting used to being lost in this new tuner world ; it's quite the jungle , and now we're looking at OBD2 stuff? I don't know as I'll ever catch up . Be safe...Bob.
