Hi, I'm struggling with raising load request on the 172H-X DME. I lifted the load tables and torque maximums, even flashed X-HP to help, but the DME is still seemingly deciding what it wants regardless of lifting ceilings. I'm so used to the N55 where the DME seems to always want to hit max load ceiling under WOT.

Can anyone share their basic load strategy for this DME? I'm covered on PID, Fuel, and Ignition. That all largely translates across.

Highlights of tables adjusted in search of more load target:

Thanks, but I figured it out. Once I sorted out it was torque driven and not load driven, all is good. The factory PID setup was horrible.
Out of curiosity, what application are you using to tune that? I've only used TunerPro and many years ago, ECU Flash.

Bootmod3. I like how it has a large number of tables defined with descriptions. Makes it easier to figure out what to do. I do find myself looking up the German table names from my n55 tunerpro xdf to find what bootmod calls them.

Unfortunately, bootmod doesn't have custom tunes features for the S63. No map switching, auto ethanol adjustments, or anti-lag. Not like the N55 or S55.

Thanks, I've read lots a good things about bm3. You don't know by chance if they've started supporting n55 e-chassis? I just checked their website and didn't see it listedšŸ˜• A very complete, well labeled XDF would be very nicešŸ‘

I don't know. But I published a branch of the xdf with more tables defined. I think fuel pump was the last I added. Stock only runs the fuel pump at 60 something % duty cycle. I run mine closer to 100% with a pure 750 and some ethanol.

It should be linked in the n55 tuning thread.

Thanks for your contributions!! You're 98g0b, right? I'm 9e60b.

I haven't seen anybody post their experience with the pure750 yet. Any thoughts you'd be willing to share? Do you have it dialed in yet?
