Break-thru: Reading ACD ECU with EcuFlash

Just read through the whole thread, it seems like all the steps that needed to be done to be able to read, view, and reflash the ACD ECU have been completed, but it looks like we're just missing a solid, easy-to-understand resource (such as for making the cable required to reflash/log) for those (like me) who'd like to start tuning their ACD ECU.

I hear ya deeman, I had a feeling it came down to a scenario like that. Sucks..
So is the tables currently defined accurate and pretty much all that there is ?
I can't find an XML worth a beans. I did find a c1 map for e8 with XML.
We should start the repository for these acd roms an XML

I hope I didn't sound like I was upset at sba. I'm not... just stating why I haven't personally forked over money for ACD tuning on the X yet. On my IX I bought the ACD tuning cable from IanEvo9MR (believe that was his name).
I applaud all the work developing the platform. But I'm waiting until someone offers to sell me a cable for $100-$350 with a list of XML defs on a cheap usb drive for various ACD roms. That's the profit.
Money isn't the issue for me. It's having the personal ability to change it and reflash. I'm only going to pay for that. Even if it's locked to the ACD computer ID to keep people honest, I'm fine with that.

has a few ACD stuff, and you can upload any new ones you find.

Is there someone who have more information on how the final ACD lockup torque is calculated from: lockup map, gforce lockup reduction, C map, proportionning map.
I would think it's:
Lockup (accel/decel) % - Gforce reduction (accel/decel) X C map? X Steering proportionning % = output to ACD clutch pack.

People are waiting to do it themselves....
Especially something that impacts handling which seems to have changing needs even more than retuning for weather.
I want to tinker. I want to go drive and hit a corner. I want to pull over then try to dial out the negative qualities of that corner. I may want to do this 50 times to get that one corner just right.

You misunderstood sba. He was one of the guys that did all the breakthroughs for ACD tuning. Check back in this thread. He did everything along with a few other guys for free. Something like tephra for the ecu roms. Some people took advantage of the open source community and started charging for these ACD tunes as if it was of their own creation. That left sba and others that actually put some grunt work into making this possible with no $ for their work (though they never were expecting it) and they watched others make profit off their work. Thats when this thread went dead cold because I'm sure no one wanted to publish any more work that would get stolen and used for profit.
That's not to say these guys already making a profit cant...ECU tuning is another perfect example. There are still a lot of people out there who simply can't process what is required to tune, so therefor they have to pay.
I've PM'd many people for months asking for hints and tips with regard to the maps...ie, what change to a map will change a handling characteristic? All I've has is crickets for responses.
Much of the XML out there is outdated and has lots of mistakes. I've been working on XML that takes more "developed" examples of XML and porting (as to say) into the older stuff. However, i'm still relying on pre-defined address (because I'm by no means a disassembler).
Anyway...I'll show you mine if you show me yours. Happy to help and share, I just need to know more about what changes in the maps changes how the car handles.

Downloaded the stock Evo 9 bin and XML from evoscan, comparing it to c1 now. Acd units are on ebay all the time. Not too pricey for ralliart ones. They have a wide variety of tunes as well..
I'm against locked tunes when privateering but it seems that we continuously get taken advantage of so let's blow that up like a hemmeroid on here!
I will eventuay get the acd pro box as I feel it's a better wheel for the wagon..

Siluck2, thats strange. The rom is a 401702, which I have previously only found in JDM Evo7.
I have not revised that xml since March 2010, so its a bit out of date. I will do some revisions and post an xml.
