BLAKE AuST

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.

Thanks Derek! that makes sense, I changed Aux1 active state from High to Low and the idle is much better and disabled over-run fuel cut for the moment. I've uploaded another log, as the idle still floats around 780 to 1030rpm or so, i'm not sure if its just bouncing between 2 cells on the fuel map or some other setting is wrong.

I've had my car tuned and it runs quite well, it wasn't wired for hold power so the idle stepper would often pop on startup and it would sometime stall on deceleration. I've now wired it for hold power which works and no more idle stepper pop. While double checking my wiring (car was an M52 i rewired to M50) i found that the idle stepper motors 2 wires going to AUX 1 and AUX 2 were reversed, i've fixed this but now the cars idle is erratic and its running really rich so i'm not sure if the tuner put a work around inplace or what for my dodgy wiring i have attached my tune and a log of the issue if you could please take a look. I also found the below, i have it wired as per the BMW and Link documentation but the ECU shows AUX 1 to be Open instead of Closed. PC Datalog - 2023-07-24 12;33;10 pm.llgx M52B28-before2.pclx

As soon as i ask for help i figure it out. in case anyone reads this and repinned a M52 harness to work with the G4X PNP, the Cam sensor harness side plug is pinned different than the M50, you just need to swap the Black and Yellow wires around.

I am using the M54 Cam sensor 12141438081, google searches says this is a Hall sensor, I just wired in the G4X and am having the same issue. The car starts and runs pretty well on the base tune, but "Trig2 Signal" always says "No" and the trigger scope seems to be missing for trig2, trig1 looks ok to me.
