Default Last safety 3: But no fuel pressure plug connected? - 08-24-2019, 01:52 AM

PWG N55 F10, just updated to the latest PWG firmware.

Running map 2 on 93 octane pump gas with default settings.

I saw in my bluetooth app that last safety was 3, fuel pressure low.
Never saw the jb4 kick me to map 4 or any SES flash etc?

My JB4 fuel pressure connector is not connected aswell, so how would the JB4 know fuel pressure is low?

No codes stored, car has always ran strong with no issues, also logs and runs strong after this aswell.
My logs look good and clean, and AFR looks good.


Here is a log from last week on the last firmware:

The firmware presumes it's attached for that. We could add a bypass for that safety to the firmware, although always best to attach it.

Even with the fuel connector NOT connected? Can this throw me into a safety map?

The interface says safety 3, but I never got thrown into a safety map.
