NefMoto

I need to pull the instrument cluster fuse (#11), otherwise Me7Logger is not working.
Is there a way around?
And why is it required on this car, and not on others?

On my car was the same thing.
Once I saw someone here telling to connect first with Nefmoto Flasher, then use ME7Logger. Works like a charm.

Leave fuse in, start Nefmoto flasher and 'connect'. Leave flasher running/open and THEN open Me7Logger and log?

There is only two options - yes or no
Is it necessary to asking those basic things and not to try yourself?

ignition on, logger on, car on without ignition off

is this working for you?


try this in your software

Are you trying to answer the question or only bored from being locked up? Yes or No?

Yes, leave fuse in. I Start nefmoto flasher, connect, then disconnect, close the software, then start ME7logger normal.

Thanks, will give it a try this afternoon.

I just tried, did not work.
Just hate driving around without rpm and speed indication.

The only solution is to pull separate Kline from ECU

The VisualMe7Logger with live data helps when I have someone else to drive.
Wouldn't know how to pull a separate K-line from ECU (to instrument cluster), what pin to which pin?

Climatronic, stereo, cluster, ECU, central electronic... They are all connected to OBD via K-line.  You need to pull wire from ECU to OBD direct. Or make one more OBD connector for ECU only, or put switch that discconect other stuff from K line.
If you don't know how to do it by yourself, there is a shemaric somewere on forum. In some sticky tread i think

have you tried any of this? its not necessary to use separate line or pull fuse

Hi all. I have the same problem on my car.
All next tried cases use same cable and same laptop.
Logger works on speed 10400 for only 10-20 seconds, with or without ignition. If i remove the instrument cluster fuse can make log at 56000.
If i make the log directly to ecu on the bench, it works at 115200 , SO ECU IS NOT A CAUSE!
I tried on 2 other cars and there don't have problem and can make log at 56000.
I got an instrument cluster from one of the car witch work at 56000 and put it in my car. NOTHING, same problem, log not work, SO IS NOT THE INSTRUMENT CLUSTER PROBLEM.
What can it be? i don't have other can slave in the car only climatronic (skoda octravia 1U2).

Are the other 'users' of the K-line 'cutting' the ECU off?
Why would running an additional cable from the ECU to the OBD change that (the other users are still connected to the K-line so we have the cluster running).

I assume other cars (A4 1.8T of similar generation?) don't have the issue. What is different?

because k-line is a shit standard. single wire, shared bus hack.

I agree with you Nyet but it is the same shit to all cars and logger works on some car.

don't skip details. Read topic from begining


What is different from other cars I don't know. Also bad cable can make problems. I have cable that work excelent on any B6 chaiss, but it can't work on B5 and C5 on stock OBD port. Porr lattency and there is a problem

ECU is connected to cluster via W wire(not K-line) than tru cluster is going on K-line OBD port. So i depend on cluster also

Marginal is marginal

BlackT, i wrote upstairs, i put on my car a cluster witch work with my cable to make log at 56000. So i think is not from cluster.
I tried 2 kind of cables , vag commander cable and galletto (clone). Both make problems on my car. 

So running another line will improve the 'signal quality' and move (on Golf Mk4 platform only) from 'marginal' (or not working) to 'acceptable' (and working, like on other platforms)?

Running a *dedicated* line will do this (that is to say, make sure nothing else is connected on the k-line anywhere else). Or, rather, if it doesn't work, it will prove something else is wrong.

Me7logger use k-line or CANBUS?

k-line. No CANBUS logging on ME7.1

I fogot to specify upstairs , my ecu is me7.5

Doesn't matter, me7logger uses kline due to 7.1 needing it.

No good canbus logging for me7.5 anyway.

Thanks Nyet
Like i said on the bench the ecu works fine at 115200 with the same cable and same laptop like i use on the car.
Maybe the kline wire is bad on the obd adapter or some negative cable.
Will try to get directly a wire for logger directly from ecu but i leave the standard kline wire in circuit, because if i cut it i think cluster will not comunicate with ecu after this.

I think you can solve this problem by using the NefMoto flasher to open a diagnostic session (just press "Connect"). Only after you have done this, connect ME7Logger.

Add a switch to be able to swap the ecu from obd connector to stock kline

I will try but first must see if the k-line in obd conector arrive from cluster or from ecu. i think it arrive from ecu to cluster and from cluster to obd conector.
Please tell me , le7logger send a one request to ecu for all selected variables or 1 request for 1 variable?
Thanks

that totally doesn't matter. clip the wire from the ecu. clip the wire from the obd connecgtor. run a wire from the the ecu to the obd connector, and add a switch that switches between that wire and the kline to the harness. done.

Thanks Nyet
Can you please tell me about reuest info sent and recived from ecu? Sincerly i try to make something with arduino and my k-line protocol not work for all pids, only few. I think what Me7logger use is other type of protocol or how it access the info from ecu. Thanks
