Hi Brad, E-throttle support was added about a year ago. Bottom board PCB revision number V1.5 and above (we are up to V1.8 now) have E-throttle pins available on the Expansion connectors.
I cant give you a serial number when the change occurred but a quick way to tell is look at the Exp connector and if Aux 9 & 10 are present you have an E-throttle capable ecu.
This note under E-throttle Aux set-up should have made it reasonably clear:
The main thing that is very confusing to new users is that in the software you have Aux 4 and Aux 9 assigned, yet on the Exp connector you have Aux 9 and Aux 10 to connect to your motor. This confusion is well "hidden" in our wirein ECUs but cannot be in the plugins without messing up other functions so we just have to learn to live with the confusing labelling. Basically Aux 4 and 9 share some electronic resources so they are mutually exclusive. Aux 4 in the software controls the Aux 9 pin on the Exp connector. Aux 9 in the software controls Aux 10 pin on the exp connector. Clear as mud...
Correct - I know it is confusing. Note you also need to have a spare aux output assigned to "E-throttle relay" (the aux doesnt actually need to be connected to anything - just needs to be assigned in the software).
