Hello, is there a bug with autotune in V3? Im on 3.054 and will update to this version tomorrow, but i’ve been having the issue that autotune is only reading very little number samples. i verified that the parameters are all set correctly (rpm window, map window etc) and changed the transient delay to 250ms, and still not getting much reading. never had a problem before on older versions ---

Not sure if there is an EDL-1 bluetooth issue, I have the latest 1.21 firmware. experimenting with a cyd dash and also a tried and tested (previously favourite) Android tablet. Pairs up ok, but doesn’t start sending data until Emu Black is connected to laptop via USB. once working, laptop can be disconnected and dash continues to work until car re started, then it is the same again. Any ideas or settings to try? ---

```auto Is it possible to disable the pull-up or down analog input?(for dbw). I constantly have problems with the lambda reading. The real AFR is always 1 AFR richer than the OEM lambda. I've tried everything from dead time to flow, etc., but the reading is always 0.10 lambda richer than the target AFR, and the lambda reading is 1 AFR richer than the Prosport one. I inserted a 150Kohm pull-up on pin 6 of the LSU4.9 and 5V, and no change. ``` ---

Could you add in the “Fueling - Corrections - General” the option to select the “Pre Throttle boost sensor”. ![V3.057 Fuel corrections general](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/d/d53662a5b152802a049e98bec1f19f0fc2eead46.jpeg) ---

Sorry for the double post, as a new member I’m not allowed to attach two images. Could you also have a look at the “Functions” “Invert output” option. It doesn’t seem to change the state of the Fn1 function (I didn’t check Fn2, 3, …. etc). ![V3.057 function invert output](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/4/4c26a2cb1e3981b4da4a49062f1c5b28ea1bf3ff.jpeg) ---

Thanks for the help. Unfortunately closing the function setup window didn’t solve the issue in my case. Screenshot of test with fn 4 and a simple function (function was closed during experiment). Second bump is with “inverse output” enabled, but fn 4 logging channel response remains identical: ![Screenshot 2025-10-08 133049](https://europe1.discourse-cdn.com/flex013/uploads/ecumaster/original/2X/9/98f320280454e248464792a9eb9fd0fc288d2c7b.jpeg) ---

OK on V2 if I remember, invert was only valid for hardware output, as you can see says “invert output” so probably if you had assigned output that would invert it… not sure if is working on virtual..
