How to create xdf file

[S.O.B.B.]

Good Day to all.could anyone explain or direct me on how to create xdf files in tprt when a bin file is all I have.I tried an xdf creater download but no luck.any help or direction is appreciated. Thanks

making an xdf is the easy part.

locating the tables and figuring out their dimensions and conversion formulas involves learning machine languages and thinking on a level of logic and flow control that would give most people a migrane

I have a few bin files from 89 cadillac fwd that I was trying to read so I could compare sa ve and just a few others.I don't need the whole thing defined.is there a way to read a bin in text form or is it all going to look like jiberish unless I have an xdf.I'm just not familiar with he but can convert.I managed to find a few titles like spark latency in hex.checksum said 4c or c4.can't remember off hand but no xdf I saw has those characters. I have a ns1 xdf but have only been able to read one bin file and it's a modified bin.not quite what I was after.I have a list of bin files but no matching xdf that I've been able to find.I'll keep trying and searching.thanks for the reply.cheers

you can disassemble the code into raw 68k processor instructions like

CLRA
LDX 0x0026
ADDA 0,X

and the tables will be in hex but you have to read the code to figure out how the tables are referenced.

in tunerpro, you can use tools > advanced > 3d data viewer, to find tables with a certain visible geometry, but it's very difficult and you might not know what they mean

you definitely need to figure out basics such as the bin's checksum location too so it can be regenerated when you change something or the ECM will barf

are you sure no XDF already exists for this platform?

Unfortunately I'm still too green to understand disassembly etc.I'm just after the stock cadillac tables from that tbi 4.5 engine for sa ve and a few others. I have a look up with all the ecms listed.ns1 is the only xdf I've been able to find.but that's for pfi and I did use the tables from a 92 eldo with 2240ecm.but I was after the earlier tbi years and by ecm listing I have not come across an xdf for any.I'll keep trying.thanks though for the advice.I lack experience in this part. But thanks for the help it's appreciated.

what ecm do you have? have you identified the mask that your bin uses? how 'bout the bcc from your prom? i'll see if i can find anything
