Jb4 installed... gauges not working. Help please.
If someone could shed some light on what’s happening and what is supposed
To happen it would be greatly appreciated.I
I have installed jb4 with wireless kit and the gauges are not reading on the app.
I will attach some screenshots to see if someone knows what’s going on.
This is with the car running and the jn4 connected to my phone.

Here are a couple of screenshots.
It won't let me add the screenshot of the gauges, but basically the only gauge that shows anything is the map gauge.

I went for a drive and the boost gauge works but not the IAT or AFR.
I did three logs in 3rd gear from 2k- redline in map 0, 1, and 2.
Clearly I have not connected something correctly.

It is a 1.6l turbo car, I plug the brown harness into the connector on the intake manifold, the rainbow connector to the harness under the stock air box and the OBD cable to the connector in the fuse box.

I have not installed any of the fuel wires.

Any help would be appreciated.

I disconnected the app and then reconnected it and now all the gauges are working.
I have attached screenshots of all the settings currently. I bought the JB4 used and want to make sure the settings are correct for my application.

I am going to go our and capture some correct logs now that the gauges are working.

Thanks again

Turn off bit 7 on PDF 3.
Turn off all that Ethanol stuff, all of it.
I would also change your FF waste gate from 60 to 50. Also did you get fuel wires?

Thanks I will adjust all this.
I haven't installed the fuel wires as I was under the impression if you weren't running E85 there is no need to on the 1.6?
