Default JB4 App lpfp reading is wrong...please help!!! - 08-10-2021, 03:38 PM
I've tried to search this and didn't come up with a solution being given, if there is please link it for me and thank you, if not my problem is simply this. My LPFP reading on the JB4 app reads 40psi @ idle and only fluctuates about 1-3 psi while driving...however in the logs, the fuel pressures are logged properly, and I double checked using just MHD monitoring to make sure it wasn't a sensor issue. Also, it didn't always have this issue.

So if there's a file I need to download, or re-download or something like that please point me in the right direction. Thanks!

You'll need to upload a log in the correct section for assistance. It could be a setting in the JB4 user adjustments.
