0411 tuning in tunerpro

**Boosted 3gen** · 02-16-2019

Ok I finally have a way to flash in tunes made from tunerpro. Very excited. Big thanks to Pete over at ls1tech.

Now my questions are,
1. Is it possible to make xdfs that can adjust max kpa? Or is this an o.s. thing.
2. if it is o.s. related and I'm assume it is, is there a 2 bar os out there?

3. Does anyone have an unlocked xdf to poke around in to see how they're made?

Thanks in advance

Xdfs just define what is already in the bin. So you can`t add new features simply by creating an xdf.
Pcm sees 0-5v from the map sensor. If the map sensor is set for 2 bar you will get half the resolution of 1 bar map sensor at the pcm. A different conversion is needed on the pcm side and maybe scaling of existing tables or adding new tables.

Your best bet is to score a 2bar COS bin and work from there. I think there is a xdf floating around already made for that COS.

These are the only ones I have found and are unlocked.
I see no reason why people lock xdfs. It only hinders other people adding new stuff and developing xdfs for other OSs. It is only a matter of changing tables and scalars addresses.

Thanks for the answers. And the xdfs. Do you know if the 2 bar cos is on this site or another, ive been looking but haven't found one.

As far as I'm aware, any 2-bar or 3-bar custom OS will be a pirated HP Tuners or EFI-Live OS.

But if anyone has created a freeware custom OS, I'd love to know about it.

I'm on the lookout for one. Also got a coding guy working on helping me make one.

If your coding guy wants a collaborator, my email address is NSFW, outlook, com.

I haven't been making any changes to the OS yet, yet but I have been doing some reverse engineering:
