XDF Progress
 
Hey guys, starting a similar thread over to here to keep those who just frequent this forum in the loop.

An XDF update was pushed today, and all 4 XDF's on the GitHub page have been updated with the following:

- 17 idle tables
- 2 new knock tables
- 1 boost solenoid PWM table

Enjoy! :)

Keep up the good work!

thanks!

Awesome, do you know what the Y values represent in the Maximum spark retard table? That's not a table I'll be playing with, just curious.

Sweeetness Jake, keep it up

ferocity02 07-20-2015 02:48 PM

So I download the .xdf, install TunerPro, import the .xdf into TunerPro, then what? Can I load my stock tune file that MHD saved? Or do I need to start with something else?

Wedge is helping tune my car but I would like to take a peek inside to better understand what's going on.

Nniftyfour 07-20-2015 03:17 PM

Pretty sure wedges protunes tunes are locked.

They weren't locked for me back when I using Cobb and ATR. I think he makes them using your ATR configuration so only you can see them. I haven't tried looking at his MHD tune though.

So I guess once you have TunerPro and the XDF, where do you start?

prelude2perfect 07-20-2015 04:11 PM

So what do those updates translate into as far as features go? Adjustable idle maybe? I'm not very tuning savy

That's because Cobb wouldn't give him pro tuner ststus. He only had ATR like the rest of us and couldn't lock his files. He's a "partner" in MHD so I think they probably got a locking mechanism for him

im going to tweak normal idle no load a little bit and mt drive off and power steering as i get massive drops with power steering with 245s up front. if these tables actually help i will be this will be great to fix little gripes i have about the car :clap:

current grips, : car idles a tiny bit too low going to up it 40 RPM to 700, mt drive off support i may bump it up a tiny bit above idle to see, as i do find the car wants to stall sometimes if very slowly let off the clutch where as it should creep forward and keep going. other thing obviously is power steering load causes rpms to drop a lot for parking, so i will up this a little and report back tomorrow.

Cheers Jake! Another donation coming your way...

As someone in touch with Jake every 2-3 days, I can testify he deserves to get donations for the sheer amount of work he puts into our beloved platform. Hats off to you Jake.

doc 335 07-21-2015 01:41 AM

Thank you for all your effort

matthewo 07-21-2015 05:10 AM

Sent you a donation, thanks for all the hard work and dedication to this platform.

Tried raising some of the idle tables 50 RPM and I can say it does work, I may tweak it a bit more but I can see this being very helpful for 6MT guys especially those running more aggressive aftermarket clutches that may need a little more RPM to engage. seems like those drive off-supports to make 1st gear engagement smoother

The units are supposed to be mg/stk, same as the y-axis in the knock factor tables. It appears the DAMOS had the formula wrong for it, so I will need to fix it. For now, just picture these values in the y-axis (leaving out the decimals) 201, 321, 441, 561, 680, 800, 882, 958. Those would be from the MAF calcs the DME runs. Shame MAF is modeled so high in places, but boost (psi) isn't close =(

If you have a 6MT, you can use the idle tables to raise you idle and get rid of the SMFW rattle that annoys everyone.

The new knock tables, I don't expect many to use unless you really know what you are doing, and run > 30% E85. If you get protuned and run E85, then expect more consistent power in the future as long as your tuner knows what they are doing! I added the for completeness.

Speaking of knock tables, there are two more "maximum spark retard" tables w/ different values. I suppose I will add them for completeness sake as well.

The boost solenoid PWM table is for the ST crowd. It will allow use of a 3-port MAC solenoid to control the wastegates.

I set all values that were previously less than 1000 in mine to 1000 across the board, and all is well =)

Thank you all! And big thanks to Martial as well, he ports over everything I find / define in IJEOS to the other roms. Gotta keep them in sync.

Jake,

Quick question,

Is it possible misfire detection for bank 2 is defined incorrectly for ije0s? Have it set to 1, but am still able to trigger misfire cyl 6 codes.

It is possible. I will add it to the list of things to double check on / fix.

Thank you!

Thanks. Terry also observed torque related timing pulls in my logs, even though the settings are toggled to disable that. Not sure if that could also be an XDF issue or just a general ije0s oddity. Cheers, thanks for the work. Donation incoming ;)

There are still a ton more torque related tables in the DME. It could be related to any number of them sadly. And IJEOS has more than I8AOS

Interesting. I just meant the 'disable torque reduction by ign' toggle.
