You're going at this all wrong... you shouldn't "convert" anything from anything else.

You should solely be defining the K box correctly (like I said most of the M-box lines up pretty good).  Then you should modify only what you need for what you want to do.  Ignore/forget almost everything you've read in the community project in terms of actual changes/numbers they don't apply here or anywhere really.

The K box (possibly from being an automatic ECU) already has more than enough load request in IRL so for a basic stage 1 you don't need to change anything there.  IOP needs a little attention, and then you will need to take care of the load limiters, timing maps, fuel, etc.

Again, you're over thinking this completely.  Define the file, and look at each map you need to adjust.  If you can understand the stock maps you will certainly see that you will have to do less changes than you think.

I found that most values are shifted a tad from the M box to the K box (what I meant by "converting" ) compared K bin and M bin in hex and created new addresses based on BIN compares.  Im actually very happy  with the K bin seems like it has a tad more prep than the stock Q...  So I am not sure if I made an error somewhere along the lines as im having power cut (I coded out the rear O2 and EGT sensors based on the WIKI). Would anyone be willing to maybe share their K Definition file? wanted to compare and make sure I didn't fudge something up with my HEX addresses... Posted my DEF file on 1st page but still stuck trying to solve this ESP issue and went off into the left field.. but there might be something obvious that I messed up that is causing my problems..

If you're having ESP intervention, my only guesses would be that either your changes to the TQ model are incorrect or some of the other changes you have made were done on an incorrectly defined definition and you actually changed something else (it. you coded out EGT, but maybe you actually changed some unknown bits instead).

Start with one change at a time if you're not sure instead of lumping everything together into one file.

Well then follow the stage 1 to the T and you will see. I have no reason to lie it's in the s4 wiki. everyone that followed the stage 1 so far has had this same Limp happen to then so far and think they pop'd IC hoses or ran things over, it's funny read the wiki or maybe some tuning books. more than likely this is deviation limp. but bullshit

He was mostly referring to this, probably:

Think I might have found the source of my issues,  did a pressure test on my piping and found a tare on the driver's side wastegate hose, oh that looks like a fun project! (hope it's just a subframe pull and not an engine rip out to get at the nipple and hose) :S

Will be back once this is fixed :S

I've "Stage 1-d" more cars than you've been in, thanks. Everything you said is wrong. The "diagnosis", the "reasoning" and the "solution".

My 2 cents, for what it's worth, about EngineeriD-Zyn's expressing his ideas concerning air flow (RAM), etc..., may have been wrong, but PRJ, you made your comment a personal one, e.g., "" SMELLS LIKE BULLSHIT"".    No matter how wrong, technically,  EngineerD-Zyn may be, you didn't give him a chance to save face. You probably embarrassed him.

I'll say this, PRJ, you may have "Stage'd-1" more cars than EngineerD-Zyn has been in, which makes you a much better "Tuner" than ED-Zyn, but I am 100% positive that there are tuners, here ( DDillenger, Nyet, SnowTrooper, Turboat, etc... to name a few ) that can and do tune circles around you. It wouldn't be cool if DDillenger made Ad-Hominem remarks at you, just because you are wrong on a technical issue.
It's just demeaning and not in the spirit that this forum is based on.

Ask DDillenger, I cannot even change a damned Bosch MAF to Hitachi, without asking for help, yet DDillenger and the others have NEVER made a demeaning comment to me. They've been patient and as helpful as possible, understanding my limitations. They certainly don't treat me like the pain in the a$$ that I probably am, with my ignorant questions and comments.

I was embarrassed for EngineerD-Zyn when I say your replay to his comment.     Now, you can go ahead and attack me, or be a stand up man and apologize to ED_Zyn.

For the record, although he is crass, PRJ probably knows more about these systems than the engineers that designed them.

Regardless, I don't think any harm was meant by anyone.

Let's all have fun Tongue

There probably are, but none of those on your list fit the bill.

As for my comment, when someone with 10 posts tells me to read the wiki, that is the only reply he is going to get.

Everything he said was completely wrong. All the "advice" given was wrong. That is what I pointed out.
Why it is wrong you can easily read up in the documentation, not my job to spoonfeed it to you, especially since it has been discussed a million times on here.

P.S. Talk facts, not drama.

Absolutely true. I don't know nearly as much as prj. Period.

The only thing I have over him is the amount of verbiage (probably much of it wrong) that I crank out for public consumption. Everybody else has secret handshakes and valuable plastic trinkets and glass beads to trade.

Sincerely PRJ, I would never presume to have you "spoonfeed" me. I hope that you didn't take my prior post as a request for help.
Those whom help me, here ( Daz, Nyet, etc...) , know why I require more than most and know why I will never have what it takes to do anything worth a damn when it comes to tuning. If they are "spoonfeeding" me, then I owe them more thanks than I've already expressed to them.
So, in the spirit of this great forum, I'd like to thank the incredibly talented tuners, ( DDillenger, Nyet, Tony, Snowtrooper, Turboat, et al,) that have taken the time to help all of us that know so little.  Thank you for your help, patience and understanding.  I'll never be a tuner, but, because of you all, I know a lot more that the moron that stumbled into this forum a few years back.

And a special shout out to Tony, without whom this forum wouldn't exist.
