Does anyone here have experience flashing these ECMs?

I have a copy of PCMFlash which will write.

But I don’t have a definition file or even the whole BIN. It errors out when trying to write the files they provided. and it won’t read the BIN.

Does anyone who was tinkering on this project have anything helpful?

Are any of the other BINs that might be close to a TSX / K series Honda defined?

I've got a lot of the tables marked out, but when I've been making the definition for it, I can't seem to figure out how to get it to display.

It must be something with the scalars. and I'm wondering what I'm doing wrong.

I can see the RPM is the X axis, 20 bytes long, supposed to be 10 elements
I can see the Map KPA is the Y axis, 40 bytes long, supposed to be 10 elements
The table data I can see, 400 bytes, should be 100 elements

The table, obviously, should be 10x10, which I was able to establish by telling EcuFlash that the scalars were x and y axis

My problem is, the data in the column and row headers is blank, and so is the data in the table. It's SuperH 7055.

Can anyone help me with what the scalars are meant to be and what the units are meant to be in the tables?

I did find that I think the tables are in init16
Looks like I'll need to swap the xy axis as well, as per some research I've done in the main "Honda Development" thread. Is it as simple as jus ticking the box?

Clicking the Swap XY and making the table int16 has populated the data as best I can see.

The X and Y axis are still populated with zeroes.. so maybe have to keep playing with that.

I also have another problem in that one map is very little.. but I can't seem to resize it for the life of me.
