These were already defined in the xdf.  Are you using the correct software (0003)?

Yes, this. We're not going to be able to support every software version for this project, but you may be able to use the  8E0909518AK bin anyways. Post your stock bin with year/model and someone should be able to tell you. My own car was not AK to begin with, for example.

I using my own bin and just filling in my address instead of his. I has the 518f not ak so I cant use his. Ive defined tons of xds but his location I copy and find in my bin but its not lining up.

I took a look at the stock log for reference.

It shows the same high calculated egts, bts fueling and high injector duty cycles.

New log!,

Looks like IDC is ramping up steadily to about 5000rpm, and then bts kicks in and IDC goes to 100%

Not sure if this is better/worse than last log or if the modification to zklamfa table 1 worked. You guys mind having a look?

Doesn't look like it worked.

Also, why is your lamfa RISING towards redline??! Can you log mrfa? (DriverRequestedRelTorque)?

I was shooting for a bump of fuel in the midrange to avoid BTS fueling. Didn't work. Should I try the other zk table nyet? Maybe run the lamfa table rich from 3000 to redline?

It doesn't work that way. They don't add/multiply like that... the ecu takes the richest of LAMFA/BTS/KR (READ THE TUNING PAGE!)

The lowest value of the three (lamfa_w, lamfawkr, lambts) become your requested AFR.

LAMFA should be what you want. We'll fix BTS AFTER you get lamfa right.

Ha ha.  Well, actually, it kinda did work, although I am not sure of what it is yet.  The fueling is better than it ever has been and egts are down.  It might be a little rich, and done completely wrong Smiley, but it did get better than it was.

So, I take it you tried to fudge the numbers in lamfa to get a richer request right away?  Did you modify the zk, tlafa maps as well?  Use real numbers in lamfa if you are modifing zk.  I think I may have caused more confusion by suggesting that in the first place. Can you post the bin that that made this log file please?

edit: I see you said you made a modification to a zk table.  Pretty sure that worked.  If you have lamfa at fake values, fix them up to what you want your request to be.

No, it did not... He just brought in LAMFA way early (like we asked him to heh)...

But since LAMFA resolution is so rough, we kinda need SOME ZK i think... if we just FF it, req afr is gonna be mega lumpy

Here's the bin file to go with the log. If anyone is new to this, they should be warned that this file contains EXPERIMNENTAL table values, and IS NOT A FINISHED STAGE 1 file.
