Faqs: Mpps only really works on the mk5 jettes, do not flash file read by mpps, when reading a Audi A4. Lesson learned. For checksums there is a med9 checksum tool right? I use winols for checksums

I do not know of a med9 checksum tool, but I dont know much.
If there is I would feel this thread would be a great place for a link.
Mpps is good on jetta, gti, eos, and a3? but no A4 i think that is correct.
I'm sure vdubnation is going to make this thread great, as far as pics vs
posting a file. I say we post the file and the xdf/kp so people can see the
changes it may help some understand same as before. I dont think there
is a way to copy and paste these so people are going to have work to use this thread
unless they happen to have the same part# as op.

almost the same here, besides i didnt mess with engine speed limiter as i didn't see a point, already dropping power by stock redline, so why go any higher?
and also i didnt touch knock recognition maps seems way too sketchy, at least for a stage 1
but i did include the optimal timing maps 1&2. found i had to to get timing where i wanted it.

also something to think about is the ecu doesnt like inj timing over 10ms

What happens when we go over 10ms?

You'll find fuel trims will be pegged at 25% as you're running out of time to inject the fuel. Bear in mind, GDI engines can't spray all the time like port injection, they have a window of about 380-70 degrees BTDC to spray. There are injection start time maps (similar to diesel SOIs) that allow you to advance injection to 430 degrees.

Hi All

Thought I would join in on this thread as I am about to embark on tuning my new to me 2006 A3 2.0T BPY  w/ MT.  I am pretty newbish  but  have some tuning experience for my  97 AEB A4 1.8t which is M5.92.  Going from this to MED9.1 is a couple of quantum leaps forward.

I've BDM cloned my original ECU and know I can flash my MED9.1 using MPPS v13.

If this is going to be a community thread, I think it makes sense to use the feely available TunerPro tool so I will be using it for my contributions.

I've located a few map packs.  This one http://nefariousmotorsports.com/forum/index.php?topic=7088.0 is for TunerPro and this one for http://nefariousmotorsports.com/forum/index.php?topic=467.30 for winols.  Neither of these map directly to my BIN but are good guides for helping locate the various maps.

Comparing these map packs, I've noticed the factor for KFMIRL is 0.023438 in the kp and 0.025 in the xdf. Furthermore, the column factor is 0.001526 in the kp and 0.00164 in the xdf.  While close, for clarity and consistency, I would like to choose the correct factors moving forward.  Any thoughts from those willing to help?

As a first step, I plan on modifying KLDRXN, KLDRXNZK, KFMIRL and perhaps the scaling and values for KFMIOP.    I am consider altering scaling for KFMIOP because it maxes at a load of 160% and I plan on shooting for max loads in the range of 170% when altering KLDRXN and KLDRXNZK.

Original maps, modified KLDRXN, original bin and xdf for these maps only are attached.

At this point, my main questions are does the modified KLDRXN w/ 170% seem reasonable in profile shape (perhaps boost should come on earlier?) and is a 170% load reasonable for a stage 1 type of tune ?.  Once I have some feedback, will flash, log and post results.

Also provided here is a stock log.   Im in south TX so outside temps could be anywhere between 80 -100 deg F for this log.  I don't recall.

 Undecided,  sigh, not much interest.  Guess I will  hack away at it and post a bin in the "rate my tune" section when done.  If anyone  needs a good starting point for tuning MED9.1 , I have been following this post as a general how to with good info:   http://nefariousmotorsports.com/forum/index.php?topic=5525.0title=.

Don't give up. Just trying to find the time to look through the thread. Thanks for posting some good info. It's also preferable to post your complete, unedited log rather than
 graphs. Also, what gear where these logs taken in?

We are listening, tomorrow is hope to join the forum with good logs! Also one of  the differences between me7 and med9 is obviously hpfp. Is there an advantage to raising fuel pressure?

Okay, thanks for the encouragement.  I took another stab at this.  I decided to use the scaling and factors from the winols map pack I found since these values seemed to agree with other posts I was reading.

I modified LDRXN and LDRXNZK from stock values by 15% across the maps. I know % tuning is frowned upon and will update this once I know what a more ideal profile should look like.

KFMIRL is also modified by +5% for 80% load lines and above so it requests enough load.

KFMIOP is rescaled and extrapolated such that 160% load is reflected in this table.

Pictures of stock maps and this (version 2) slightly tuned maps are shown.  Also attached is a stock log file and this version 2 log file. This v2 tune log was  done at about 90 deg F.

As seen in the log, I do not reach values shown in LDRXN in the  v2 tune.  I suspect it could be
KFLDHBN  limiting me.  I set LDPBM to 2550 across the board already.  Im  wading deep over my head  into FR to see what limits the load values but slow going after hitting a suggestion that it could be the exhaust gas temperature model.

Don't touch the spool area or you may get a pos deviation code.

I tend to max KFLDHBN until my boost response is where I want it, and my boost pid's are inline. Then, I go back and set it slightly higher, so it does not limit charge pressure, but still provides a margin of safety. Take a look through the stage 1 list posted here, and you may spot some other values that can limit you. Are you sure you're requesting enough load? Also, in MED9 files there are multiple LDRXN's, and some other maps. Either modify them all, or figure which ones pertain to your variant coding.
