You are getting voltage at your pin #4? I have a digital meter that gives from 3-45v and it’s getting nada. I have my JB4 on the driver side of my vehicle and everything else on the pass, so I was thinking maybe extending the white wire and the voltage being only .5 that it might be causing an issue, but I’ve stuck the meter in the harness terminal for the white wire all along the line and it gets nothing.
Idk I never checked it, rained this entire week till today and left my fluke at work
They never shipped mine they expect me to ship mine back first. Maybe I’ll take a voltage reading.
So I took some readings today with my fluke multimeter.
I def don’t build auto systems for a living, but I know enough that if I don’t have anything directly from the fuse box and into the initial harness where the white is, something is not right. So I’m waiting on the new DAC and I will definitely update you because I re-ran all of the wires from my car today and made sure everything is completely on the up and up. So when the replacement comes, I should be able to just, plug it in and then turn my car on and get a reading.
It appears I read 3.285vokts everywhere but pin 4 to ground with everything plugged in and car in ACC. So the output of the analyzer has to be off. And what are the odds they get 2 RMA’s within 24-48 hours same issues
this is where I tapped mine.
I got the new one and swapped it yesterday and nothing on the reading in the JB4 app. I honestly give up.
It seems highly unlikely to me that the DAC is getting enough power and data to transmit proper ethanol and fuel temp readings to the Fuel-it! app, but not to the JB4 app... both of us having the same issue is just too coincidental; and the new one not working for me kind of says it all for me.
Thank you, question of the moment is do you get correct ethanol readings in the JB4 app if you have the e85 up in your display? Neither one of us can get the content to display in the JB4, just the fuel-it! Thank you.
Damn you new one doesn’t even work either?
My grounds are good. I have power at the red terminal. I don’t know… I was hoping you were going to come up w the fix
Stick a paper clip in all the harness terminals where the white wire would plug in to make sure getting a good read. Also being limited to a minimum read of 3v is probably why not seeing anything as my 3.2 volts they estimated to be around e60 and they were right a little high (e62). Sensor voltage changes by content you’ll only see a full 5v with pure 85% maybe 100% depending on sensor range.
I’m on e62 now, so I should be getting 3.2v? Should the first white terminal in the harness coming from the fuse box have 3v or only after the DAC in the harness?
You should be seeing 3.2 volts at that level, yes.
Thank you. Going back and forth now. They asked for a log and said everything looks good, but they wanted me to zero out the settings for switching maps with the wiper switch. Are you running your wiper control? I’m going to delete it and try, but I know that’s not it. My meter goes down to 3v so I am going to test it right before it goes into the JB4 and then right where it comes out of the analyzer. It has power, the Fuel-it! app is connected and working fine. They didn’t ask for me to send mine back to test. Are you running separate power for the FSB and Fuel-it! or both off the same?
negative no wiper control. I run the jb4 app on my main screen using my CarPlay AI box as well as fuel it so changing maps is easy enough as it is and I don’t change maps much leave it my custom map 6 and now with my BEF getting insane timing.
