Another thought about the boost problem. I think that you needs to back a step in the logic that Bosch uses to determine boost. It has been said many times on this forum that you don't tune boost, you tune load. Load determines desired cylinder pressure. One desired pressure is known a calculation is done to come up with desired boost. The ECU then finds the delta of desired and actual boost to set N75 duty cycle.

Since you don't build boost it means that desired cylinder pressure is not where you want it. That in turn means you aren't meeting the load level that you want. Since you've already set LDRXN to allow a peak load that could theoretically reach your desired boost you need to take a step back in that chain and figure out why your requested load in KFMIRL is not being reached.

I notice that you changed KFLDIMX, from the map description I think you may be on the right track. Did it make any difference in boost? You said that gwerks told you it was stronger but I know he wasn't able to test much. Did he say anything about the boost specifically?

It just occurred to me that we both did somethings drastically wrong. KFLBTS is desired lambda. You need to go back and re-read Nyet's info about desired AFR: http://s4wiki.com/wiki/Tuning#Desired_AFR.

KFLBTS becomes active only when calculated EGT becomes too high and calculated lambts is lower than lamfa. For the purposes of this post I'm going to ignore all intricate details that Nyet describes about how the maps relate to each other and how to calculate lambts. What's important is that you actually increased requested lambda not decreased it. Higher lambda values means leaner. Effectively you had disabled any component protection via this map because lambts would most likely always be higher than lamfa. You would continue to run hot and have no way to resolve it except hopefully getting pushed into limp mode.

If you look back at your rev1, you raised the whole map by 0.2 lambda which basically meant that for a large portion of your load/rpm range you were requesting an AFR of 17.69. And, remember that spike I asked about? Yeah, that was a requested AFR of 19.41!

If you want to add fuel under high EGT you need to lower lambda value via KFLBTS. I think this may be a really, really common mistake for newbies like ourselves.

Something that may be helpful to note is that Nyet actually has two different KFLBTS definitions. One map is scaled to lambda (1.0 is stoich) and the other is scaled to AFR (14.7 is stoich).

I've updated my XDF to re-order these maps so that they are listed together. It's attached.

I don't mean to thread jack, but I wanted to let you guys know I posted my base stage 3 tune: http://www.nefariousmotorsports.com/forum/index.php?topic=426

I feel this tune is a good starting point as I have tried to do everything "correctly".

It is the tune I run in my daily driver, but it has never been tested on the dyno.

Please use this as a reference of what to do or not to do.  

Been pretty busy lately and just tonight got to take a look at the files...

Jude, yours threw the "17963 Charge pressure: Maximum limit exceeded" code but I'm assuming you've already taken care of that after having looked at Tony's stage 3 file. That's definitely been a help. I've taken that as an example and done just some minor changes for the time being. I don't want to do much until I get a wideband. I'll also be getting a turbo back exhaust here soon so I'll pick up the tuning more then. I'm still going to play, just not very aggressively..

Hope you're having fun with Tony's map as a base!

Glad to hear you guys are finding the file helpful. Let me know if anything in there looks weird.

Rev 3.1 is up
fixed limp mode from launch control

tony, thanks for consulting with gwerks, my tester, on this.

lol Yes, gwerks definitely finds the glitches with stuff.
We managed to fix the launch control for rev 2, but rev 3.1 still needs work.
3.1 is said to be great except for the launch control, it has a  much stronger top end.

Yes, thank you.  I will fix it. 
I'm going to try and sort out the launch control on rev 3, it still hits limp mode but in rev 2.1 launch control does work.
