Data logging EEC-IV

[Flyinghorse]

Has anyone tried data logging on the EEC-IV?
I did read a Bosch 1300/ snap on MT 2500 / actron elite could be used with the correct adaptor to log OBD1 data streams from the sensors feeding the EEC-IV. I don't believe that the obd1-obd2 adapters work unless your analyser can read obd1.
I'm not interested in fault code reading as can do that, and I can also back probe the sensors with a dvm easily, but wanted in particular to look at the long and short term injector fuel trim values.

I could couple up a moates quarter horse but really just want something simple.
