Looks like you put E216h at storage address 0xE2h...You need to put 1160 aka 8804h.

I use Romraider. and try to edit ecu def v0.42.xml with 0 succes ..

busterhax Please Please if you can to edit the bin attached with the correct value of 1160

I try to do this over few months and nobody want to help me. I believe is very important that signal when I tune my ecu

Thank you

Did you try what busterhax said above??

I did what he said to do in your file.

**Checksums are not corrected**

No problem.

I checked and correlated against MS41.1 and MS41.2 and address 0xE2h is the ONLY one that makes sense. But without programming code disassembly of MS41.0, we can never be sure. .... EDIT... Well of course d_munter already confirmed this earlier. His word you can trust.

Until now I have converted to to ms41.2 for vss signal ..but I get misfire at 6400 rpm. I have tried all tuning mods to avoid that misfire. but front sensor is the problem.
Only to disable misfire detection (still learning)
If your corrected file doesn't work I don't what to do anymore...

Thank you again

You are welcome! It should work correctly now.

I hope I didn't sound rude above.

This isn't yet in the RomRaider definitions, so I had to edit it manually using a Hex Editor (HxD).
Let us know.

for MS410 (?) its 5858 @ 00E2h, for MS411 its 6089 @ 017Ch

Is there any way someone can modify my file to calibrate the VSS? I am running MS41.1 and the calibration has not been added to the romraider definitions yet. Thanks!!

What do you need help with? The answer is in what you quoted. I don't see how this will impact dyno tuning, especially on 41.1. The VSS PRM limit is defined so you can set your rpm limit to whatever you want.

I don't know how to find/change that value in my .bin. I know some maps are based on speed and I don't want my VSS being off by 5.3333 to effect when my vanos comes on as I will be attempting to tune at various loads/speeds
