hey all,

Im trying to track down a timing oscillation I'm having, and I'm having a ball since I don't know how to disassemble yet. I have tried going through a ME7L .ecu file and finding all the torque variables I could, but I could only find mifa, misol, and miszul. I (think) I located KFDMDARO and KFDMDADP in my file, and set the 50% row to 100, but the oscillation still persists.

IRL is stock except for last five columns, and IOPs axis has been rescaled and the table re-interpolated using MasterJs tool.

I have attached a log to the post, I welcome any opinions. Disregard the WGDC, that is from KFLDRAPP.

No log attached? Also, did you recalculate KFZWOP/2 and KFMDS? They share the axis with IOP.

Posting the actual tables is good. MasterJ's tool doesn't interpolate properly, I tried it but now tend to do it by hand.

lol, you got me before I could add the log from my VM.

Yes, KFZWOP/2 is recalculated. KFMDS is NOT, however. I recall reading somewhere that is only lower RPM but I could be wrong. Ill take a look for that.

EDIT: tables attached to this post.

You're going to need to log a few more torque variables...

for IOP intervention, mifa/misolv and mibas/mizsolv, for ARMD mkar/nmod/B_ar/B_tvarss/ndar/dmar

That's where I'm stuck. I don't know the addresses of those variables for my 018CH file.

Here is another log of the problem. This log really shows the problem.

I found KFMDS earlier, and am interpolating now.

Since dd mentioned KFMDS, I plugged the stock values into excel and extrapolated the values two different ways. Should I follow the curve or linearize on the load axis?

The curve matching is better IMO, as drag torque still increases with RPM but decreases with increasing load.

I believe I fixed it. My KFZWOP table had a lower value than my KFZW in the same area. Re-interpolated KFZWOP to suit the new axis again and all is well now.
