Quick question about jb3

Hello all members here..

I am using jb3 1.3(map5) currently and I have quesiton to ask..

This morning, my car had extremely low gas it went down to 5mi..

And then I pumped the gas...on the way back home I felt power reduce(felt like stock)

Possibly jb3 automatically turned off due to low gas so I proly have to set it up again...

If anybody knows about this kind of future, pls let me know thx(want to make sure) .

Hello. I don't think the JB3 monitors you how much fuel you have left. Regardless, you put some gas in and cycled the car's power. You should still be in map 5 I believe. is there a way for you to verify what map you're on?
