Hey Biggiesacks, when you say you think its just a XML.... its a good option to try with e other Tephra File?

Because i have 3 different XML. Acutally i tried with the 105 KB File

 

If you change the ROM ID of the tephra ROM to the stock ROM ID it will open in ECUFLASH with the stock XML. You can compare them that way if you like. Some things obviously won't be right, but only things that tephra has modded. So the immobilizer stuff etc. will be the comparable.

 

Slowly it makes me crazy

I tried today to Flash with three different Tephra Files (all in the attachments). But the engine still don't start. Just crank

I also tried to disable the immobilizer in the FAA Periphery, still just engine crank.

I also tried to set the immobilizer to FFFF like they say in Merlins How To Do....., still just engine crank.

So there has to be something wrong in all three tephra Files? I think thats weird.....

Maybe somebody know tephra good enough to check it in the attachments....oder with team viewer? Or oder solution

 

Finally Problem solved

I was using the wrong tephra file
