Alex Deyth Posted December 6, 2017 Report Share Posted December 6, 2017 Hello, it is possible to upgrade from Drive by cable thottle to drive by wire throttle on a Link G4+ Plugin WRXLink (7-9) Ecu ? It seems i cannot assign aux 9- to E-throttle (+) or (-) Aux 10 is not listed at all Need to use aux 1-4 for EThrottle Signal 1 and aux 5-9 for Ethrottle Signal 2 ?? Sorry for bad english Thanks Alex Quote Link to comment Share on other sites More sharing options...
Alex Deyth Posted December 6, 2017 Author Report Share Posted December 6, 2017 After reading in more detail the help of PCLink G4+ Correct me if wrong : Motor (+) - EThrottle Signal 2 - Aux Output 4 Motor (-) - EThrottle Signal 1 - Aux Output 9 or inverted according to polarity of throttle motor Quote Link to comment Share on other sites More sharing options...

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).

Alex Deyth Posted December 7, 2017 Author Report Share Posted December 7, 2017 Thank you Adamw, the help is a bit confusing, but at least it's documented will try when i get the hardware. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted December 7, 2017 Report Share Posted December 7, 2017 Where is this info in the help file? Also when did support for ethrottle get added to the ver7-9 units? Is there a break point in ecu serial number? Quote Link to comment Share on other sites More sharing options...
Alex Deyth Posted December 7, 2017 Author Report Share Posted December 7, 2017 The info in help files is located in : G4+ ECU Tuning Functions / Electronic Throttle Control. After that is a little mess. I have found the "solution" for me in the Help Browser window in the configuration table of PCLink. Selecting a auxilliary output, PClink throw a list of possible output. For me the ver7-9 unit is capable of controlling EThrottle, because in help file, there is a 2 differents versions 7-9 units : WRXLink (7-9) WRXLink (7-9) With EThrottle The pinouts for expansions connector are not the same and my unit pinout matches the EThrottle version. So I guess my version is capable of Ethrottle control Quote Link to comment Share on other sites More sharing options...

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. 6 hours ago, Alex Deyth said: The info in help files is located in : G4+ ECU Tuning Functions / Electronic Throttle Control.

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... Alex Deyth 1 Quote Link to comment Share on other sites More sharing options...
Alex Deyth Posted December 8, 2017 Author Report Share Posted December 8, 2017 Thanks adam for clarification, it's explain why Aux 10 is not listed in the Auxilliary Ouptut in the software Quote Link to comment Share on other sites More sharing options...
