I've started making a XDF for the Euro S50 with the 075 DME.

I haven't gotten too far yet but I'm wondering if someone can locate the injector constant o2 adaptation? Or if anyone has some literature about locating these two items?

I've posted the bin file and current XDF as well as the VNC file and XDF for future reference.

Injector Constant - no problem...i can share
not free...

I’ve identified most bytes, constants and tables in this bin over the last few months. I will post it for free once I finish the labels for all maps.

All injector constants, speed, rpm, o2 and lamba maps.

That is fantastic. I won't be onto 075 DME for a long time. 413->506->075. I only have verified the MAF table for conversion purposes.

Excited to see your work come out.

I looked at your files and some others. Your BIN is 2 32k bin that are exactly the same as each other stacked. The references in the bin code are all to the second half. So I think you should reference to the second half of the bin in your xdf maybe. Other dumps are only 32kb and just get offset x8000 to make all the location references work.

The injector constant location, I have my money on xEB00 location. Value x71C0 ( in the bin as C0 71). Puts the value at 29120. If I did it right that is about a 25-26lb/hr injector. the #701 injector that the s50b30 uses is not in my injector info but I should add it. Internet says it was between 25-26lb/hr

CAN NOT just change this value, every table that references LOAD needs LOAD Axis scaled by the "Inj. Constant Factor"

Below is based on the stock 413 m50 injector being 17.16 lb/hr @ 3.5 Bar.
See injector size info.
