Thread: Logging Values NOT Being Displayed? (Fix in Here!)

Exactly.

#7, 14, 15 for all OBD1 ECUs.

Hi there !
I Have logging issues when the car is warm and its like blinking maps and all data and then stall and wont show me live data logging any more !
If i shut car down , disconnect nemu usb cable and let it coold down some 10 min , then start car and connect nemu to laptop , its start showing me all datalogging again but it works like 10min and then same logging issue.
I'l checked all wirings , have cutted these 7 , 14 ,15 wires from harness, nemu 3 wires are strongly soldered to this 7,14,15 pins.
I have tryed new USB cable.
What if i try this snap shok core on these 3 wires in ecu ? Can it help ? Need to resolve this problem because i can't tune like this.
Have any one this troble like me ?

If something is inducing electrical noise on the communication wires than a choke would help. They are cheap enough and worth a shot. sounds like a noise issue with something.

It could even be the orientation of the wires where you have them cut on the harness... meaning you might need to push them up away from the harness or literally remove the pin from the ECU all together.

The only reason it would fail is because of USB interference.

So just came from garage .
Placed brand new ferrite choke core on this 3 wires what connect to nemu in the ecu . Removad 7 ,14, 15 pin from ecu harness now, no contact with any wires on these pins.
And tryed to warm up engine and its doing same thing with live data flashing maps and then stall live data.
But i can do changes and then upload these !
USB cable is new quality USB A - mini B 1,8m with ferrite core.
This thing is the biggest problem for now because i cant it tune like normal on the dyno or road !

Since it is affected by temperature, it could be a "cold" solder joint. You might try re-soldering the 2x20 header. I don't mean removing the solder that's there. Just re-melt the solder on each pin with a soldering iron.

So tryed to re-soldering 2x20 pin connector , all solder joint are ok and have good contact.
But still same logging problem when engine is warm .
Im getting angry because this thing and i dont no what i can do more to go near where the problem can be !
I think i'm only who have this problem ?
What i can try more ? Have someone any idea ?
At the moment i have done:
Re-soldered solder joints 3 wires and 2x20 pin connector
New shielded USB cable
3 wires at pins 7, 14 ,15 are removed from ecu harness
Placed ferrite core on these 3 wires in ecu.

What you think if i try this - when engine is warm and i getting logging fail i get ecu out and try to cool down it with compressed air in spray bottle and see what is any changes in temperature affect some thing ?

Have you tried replacing the small female USB cable inside the ECU?

I replaced this cable what i have got with nemu package! I bought new quality USB cable - USB A to Usb mini b ! new cable going directly in to nemu board and the other end to my laptop !
So its not cable issue !

When you say it is stalling, do you mean the logging is stopping, or the engine is stalling (stops running), or both?
