I think you are in the same boat as user s4rmm. He also can't connect to 0x11 while instruments cluster
turned on.
If I ever find the time, I will add a new connection method " double slowinit to 0x01" to the ME7L.
This is a connection method that should always work. The drawback of this is, it is only possible while
the engine is not running on most ecus. But I think it is possible to patch the image so this check is no
longer present and then it should be possible to connect using "double slowinit" even while the engine is running.
If you have access to the cables and dont fear the work, direkt K-line should also be a solution.

s4rmm actually lives in my little town  He has a K04 S4, I have RS4. In older cars, when I wrote fast logging for the ECU (custom protocol), the immo shorted K-Line to ground. Basically I sent it 5 baud init, then it let through a little bit of data and shut it down again. I think it's actively monitoring communications and if it sees something it does not like, it shuts down the line in older ECU's. Do you think the cluster is also shorting K-line to ground? Because if it is, then I will not only need to add a direct K-Line, I will also need to add a switch, which will switch between the normal K-Line and direct K-Line, if I want to log anything else. Or do you think just bridging the lines will be enough? (that didn't work on older cars for me with Immo 1). Also, you are saying that engine has to be off - if it is off, and you connect, will it stay connected after you start the engine? If yes, then it's not a problem... |

Oh yes, sorry, forgot that you will need a switch to separate ecu from regular K-line.
I did it using a relais which disconnects the bus from ecu when activated.
When I plug in my diag cable to the new direct-ecu-connector, a bridge between
two otherwise unused pins in the plug activates this relais and I just communicate with the ecu.
If the bridge is not set in the plug, the relais stays released and I can e.g. monitor
the traffic on the K-line at ecu side.
I have made some logic analyzer traces of the diag connector and same time of the ecu
while instrument cluster is on. You can nicely see how the instrument cluster "disturbs"
the line!! I'll prepare them and post in the communication protocols section soon.

Okay, so...
I cut the K-line coming from ECU. Then I put a relay on there (or a three pole), I then connect the ECU to one pole, then to one switched pole I connect the K-line wire that I cut, and to the other switched pole I connect a new K-Line wire.
I then run the new K-Line to the OBD II connector.
Will it work then? Or do I also need to disconnect the cluster from the OBD II connector?

I just did the following:
( whatever ) Switch +-----+
OBD-Connector O--------( is in )---o____O---+---| ECU |
( the line ) | +-----+
|
NEW-Connector O--------------------------------'
Switch open -> NEW connector can be used to communicate with ECU.
ORIG connector can be used to communicate with all other devices.
Switch closed -> ORIG connector can be used as previously.
NEW connector can be used for MONITORING the bus at ecu side.
If you want to use just the original ODB-Connector, you should
disconnect also the original K-line at the connector side.
You need a BYPASS of whatever is in the line between OBD-connector and ECU:
Switch ( whatever ) Switch
o----( is in )----o +-----+
OBD-Connector O-----O--__ ( the line ) __--O-------| ECU |
o-. .-o +-----+
| |
'----------------'

Ok, I understand, you added a whole separate connector.
Pretty good idea with the relay also, I like that.
I think I will take a 2x2 adapter cable I have, gut it and run the K-Line and power to it, as well as the relay positive voltage or ground.
That should work just fine. I guess I need to start the car first (so immo can talk to ECU), then plug in the connector, and I can log.
Thank you...
Now if you only could add some sort of instant output mode to the logger, so I wouldn't have to hook it to get the data in real time ... but I guess not all wishes can be fulfilled.

Slightly off-topic but my ECU rebooted while logging tonight exactly when "The Application Experience service entered the stopped state." showed up in the event log.
I'm guessing the ECU was waiting for a message or got an incomplete transmission and decided to reboot?

Any chance that lamfawkr_w can be added to the main list, or can somebody post the address for it?
I want to see if lamfaw-lamkr is being used to enrich below lean best torque at WOT instead of lambts on my tune.
Thanks in advance

I believe that all that needs to be done to successfully use MarkP templates (and others) are some changes to ME7 .ECU/.CFG files and any ECUX template should work without any changes to template itself (which is preferable):
1) Activate [Alias] columns for the .CFG file by removing ";" sign in front of them. This will force logger to use column names from CFG files not .ECU file. Useful for people who want to use one .ECU with multiple .CFG files and not necessarily having mtaching column names, like me...
2) If you want to preserve original vfil_w in km/s:
Make a copy of vfil_w file in .ECU file, call it vfil_w_miles, and modify "A" column to "0.0048555" (which is a product of original 0.0078125 divided by 1.609 - how many kms in a mile)
Modify vfil_w line in .CFG file to say vfil_w_miles. You will now log speed in miles
If you don't want to preserve original value, just modify the A column for vfil_w and you're done.
3) IATs. Do the same as in #2 if you want to preserve original variable in Cs. Regardless, the formula changes to A= 1.35, B = - 54.4 and you now log in F.
Don't ask me in detail how I arrived at that. It takes just a little bit of arithmetic, use two formulas for C to F and the one used in logger and a bit of shuffling stuff around and here it is.
4) Timing retard: Modify dwkrz_0 - dwkrz_5's column A to "-0.75". Retard will now be positive in the logs as originally it is a signed value and is negative.
This leaves one outstanding thing which is timestamps. I will ask Setzi for an option to output EcuX style time stamps in a format "mmm" instead of current "s:mmm". Regardless, a simple replace of "." with "" in excel takes care of this.
Enjoy.

btw ECUxPlot can take care of whatever translations you need (including unit conversions), just email me and i'll try to add them.

Ok, I have a .CFG/.ECU combo file that works with any EcuX tool sans the timestamps which would have to be modified by hand. If anybody is interested, give me a word and I will share.
Thanks.

One correction though, tans (IAT) calculation requires: A = 1.35 and B = 54.4 NOT B = -54.4 as I originally posted.
Thanks.

I'm not sure if this is supposed to work, but I just tried it on a Volvo ME7 with limited success.
The program was unable to open COM1 where I had a real RS232 to KKL interface. (-p 1)

can't open serial port 1
Initialization failed, exiting ...
exiting (cause=0x1)...
USB KKL at COM3 gave the same error.
But with -f option I was able to use the USB version.

I have a RossTech KII-USB cable. Works fine with NefMoto Flasher. Was wondering if ME7Logger can work with this USB cable or just the ebay USB cables?
