Still have no solution to reading LTVs from my e39 2.8tu '00 with CA sw.
Could that be a reason of CA sw?
I have no cats (China headers) so rear o2s disabled in partial flash.

The ECU is responding with 1204B0A6, the B0 part is not a positive acknowledgement and the Logger doesn't get the data it expects.
I'm not sure what the problem is, the ECU is not responding to a read of address (0x0922) command.
I'd need to compare this to a similar MS41 LTV request, maybe a hint there.

What happens if you change the address in the ECU definition file to:

I believe the reason why the ecu is returning a B0 response is because the 1208060009220433 request doesn't specify which page to read from.
If we want to read from address 0x0922 the request should look like this 120906000009220432

Hence the reason for my question about changing the address in the XML definition.

I'm having same issue with no readings from LTV, on CA software version. I've read whole topic but I'm still confused how to change the address 0x092.

Can someone please have a look at mine data logging ?

Thanks

You can use a text editor.

PS: On my ECU lable of MS42 is 5WK9037 Index 04
Same time, INPA / RR logger identify ECU id as 7526753. ms4x flasher reads my ecu as 0110CA. Car is 2000 bmw 528 MT EU
in MS42 ECU def v0.40 there are NO 5WK9037 with id 7526753

It looks like you may have changed the address in a definition file not used by RomRaider. Make sure you change the file that's listed in the Editor Definition Manager, also make sure you restart RR after you save the change.

It was identifying your car in the previous rr_sytem.log you posted:

Code:

486868 INFO  [AWT-EventQueue-0] - CAL ID: 0110CA, Car: 2000 EUR/USDM BMW M52TU Full 5WK90329 MT/AT

Try this v0.41 definition file instead:

Well, maybe its fully identical ECUs. I will check v0.41 today later and update post. Thanks.

PS/ Great! Logger shows LTVs now! I just noticed that all 6 tables are same values.

I have tried this definition file and logger shows LTVs now. Thank you.

Can anyone help me with LTV Table. Everything is working fine, apart for LTV. Whatever I do, I get this error code :

Quote:

60026 ERROR [SwingWorker-pool-2-thread-3] - Retrieving vehicle info & A/F values... Error retrieving values

.

Can you post the rr_system.log?

Here it is. Thank you for reply !

There's a negative response to reading the Knock Adaptation Table index address 0x0000C473.

Code:

57914 DEBUG [SwingWorker-pool-2-thread-3] - Mode:0 ECU Request  ---> 1209060000C47301AB
59920 DEBUG [SwingWorker-pool-2-thread-3] - Serial Bad Read response (read timeout): 1209060000C47301AB1204B0A6

Are you able to log parameter id="E99" name="Knock Adaptation Table 1 Index **" ?
