Totally wrong way to grab that data and post it...

Use a screen grab while you are on the actual code. If you don`t understand check what everyone has done in the previous post.
What you got is just hex strings displayed as .long

I would suggest to practice your ida skills a little bit more and check the forum on previous posts on what has been done.

Posting your original file and describing what you are searching for is also a good thing.


Sorry. Is this better ?

I have done 5120 MED9.1, but in a "brute" way, just rescaling everything, apart from fueling.
I believe it can be done in a much more elegant way, since there's a bunch of 5120 stuff already in there.

Not enough time to research it right now. Maybe some day. Smiley

You can easily compare a file from a golf 5 gti (bwa) with a file from an audi s3/cupra
and check what needs to be done ith a little bit more scaling if you are using a bigger map sensor.
By compare i mean disassemble and compare the code.

but that doesnt help me ? both would have max requested boost @ 2550mbar..  255 x 10...
it not like scaling gradient and offset of boostsensor..

as far as is see its not like ME7 on MED9

It's not like ME7, but you can do it brute force like ME7 if you want.
Or if you are more clever, you can do it a little easier.

But I can't help but get the feeling that you are looking to get a free handout.

iam not looing for a free handout, we are already studying the process, but its not that easy to rewrite the sourcecode if u havent learnd the scripting.
tuning files in ols and programming scource codes in different script languages are 2 pair of shoes.
iam also open for buying help or trading...

Hello Lads,

I've got the MPCxxx Instruction Set and which should help people with the explanation of the Assembly Language seen in IDA Pro when looking at MED9.1 Binaries.

https://cache.freescale.com/files/product/doc/MPC82XINSET.pdf

How much progress have we made?

different script languages

No ECU software in history was written in a scripting language, as far as I know.

TOC and SDA addresses are always the same in MED9.1?
