Witch way to you use to readout the ecu ?

I don´t expact ECUflash doing the job ..

Try to open the dump in ScoobyROM and you will find all 2D and 3 D maps. Compare them with known Subaru or Mazda EURO4 diesel dumps. I think this way provides enough maps for a normal tune and do not need to debug the code...

Hi dude, mailed you abuat that a while back, never got back from you :)

I did use same routines as with Suzuki, targeted SH7058 with AUD reading. Flashing with Renesas FDT.
Programming procedure over OBD is probably in the file if someone can reverse it... Nissan CAN protocol.

I have used ScoobyROM to parse .xml´s and it works well, but problem is almost no maps at all have same locations or sizes as Mazda or Subaru...
Then mine is an EURO 3 with very fewer maps than the EURO4 for an example. And if i misss ONE limiter nothing will happen.
If you see any patterns with Mazda/Subaru please explain, but i am afraid i need to do this with Navara specific basefiles and tuned versions of them.

If not any kind soul can help with the reversing of the code so it gets 100%.

What maps have you found/identified/data types/conversions that are spot on so far?
