Ruff Posted January 2, 2021 Report Share Posted January 2, 2021 hey all, just started working with link g4x and am in the process of setup/tuning. im all set as far as the install and initial setup .it is a bmw m50b25tu plug and play. what i am inquiring is, speed input to pin 42 (DI1) reads inactive. is this turned off, not configured or not getting a signal input from speedo. before i invested a crap load of time chasing the signal, i thought i would ask ty jack Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 3, 2021 Report Share Posted January 3, 2021 Looking back at older base maps I suspect the DI1 pull-up resistor is meant to be on, but it is off in our G4X base map. Can you try turning the pull-up on and see if that solves it. Quote Link to comment Share on other sites More sharing options...
Ruff Posted January 13, 2021 Author Report Share Posted January 13, 2021 hi adam , thnx for the reply. i turned the pull up resistor on and still have no speed being seen in ecu. ive gone through the speed signal circuit from the combination meter and all is well there. and the bmw speed signal goes to everything from combo meter. any thoughts? id like to get this working so i can move into gear position so the tuner has more info to go on thnnx jack Quote Link to comment Share on other sites More sharing options...
Adamw Posted January 14, 2021 Report Share Posted January 14, 2021 You will need an oscilloscope to check if there is a signal on pin 42. Quote Link to comment Share on other sites More sharing options...
BLAKE AuST Posted July 26, 2023 Report Share Posted July 26, 2023 Hey Ruff, do you figure this out? i have continuity from the cluster to DI1 but it remains inactive, changing the pullup setting does nothing. Quote Link to comment Share on other sites More sharing options...
