Title: moving onto med9, first time tune golf 5 gti Post by: airtite on January 23, 2013, 03:59:08 AM Hi Guys
As the topic states, going to be tuning my golf 5 GTI 1K0907115E busy creating a definition file and have found so far LDRXN/ZK KFMIRL/S KFLDHBN doing exhaust and downpipe on friday, have ordered the intake and will be ordering a audi S3 IC, so will be looking at a stage 2 tune. What else will I need to look at apart from the usual maps? still need to locate KFMIOP KFZW/2 KFMLDMX KFLDIMX LAMFA any advise would be great. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 23, 2013, 06:50:40 AM KFLDIMX at 1CE3B6?
Title: Re: moving onto med9, first time tune golf 5 gti Post by: SVSPORT on January 23, 2013, 11:52:58 AM Is it DSG?
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 23, 2013, 10:17:43 PM yes its dsg
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 24, 2013, 03:39:56 AM another question, I dont seem to have a checksum option in mpps for this ecu, from the research it looks like the security mechanism on these med9 platforms uses some sort of RSA encryption. My question is if I change maps in the file do I need to checksum the file or can I just flash it back to the ecu and the mpps software will handle the encryption side?

My question is if I change maps in the file do I need to checksum the file or can I just flash it back to the ecu and the mpps software will handle the encryption side? I'd be real careful with flashing anything MED9 without the most up to date checksumming. At least make a full backup first so when you brick it you can flash it back to life. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 24, 2013, 08:02:23 AM I dont have access to a bdm device, my mpps cable is v13 and had no issues reading the file. I will try write the original file back to the ecu and see how that goes and take it from there.

Title: Re: moving onto med9, first time tune golf 5 gti Post by: RaraK on January 24, 2013, 10:48:41 AM i wouldnt touch it without having at least a bdm clone on the bench.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 25, 2013, 12:06:56 AM i wouldnt touch it without having at least a bdm clone on the bench. I would if I had access to a BDM. I was feeling quite confident about trying this out but your posts have made me reluctant to tackle this now......... there are quite a few local tuners using alientech cables and all sorts tuning these med9s surely my MPPS (yes its a clone) should work? It connected and read first time although it did take about 15minutes to read the whole file. Title: Re: moving onto med9, first time tune golf 5 gti Post by: k0mpresd on January 25, 2013, 12:26:18 AM bdm clone is like $30. for the $ its a great buy. very handy.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: scalp06 on January 25, 2013, 01:36:37 AM Many med9 ecu are instable during writing.
The first I've write has error during writing then no solution to repair! No solution with bdm too because I haven't make a full backup (flash+eeprom) before writing. Cost +- 1000$ for a new ecu (few years no solution for immo off med9). Today I make bdm backup before each flash on this ecu. Maybe you are lucky? ;) Title: Re: moving onto med9, first time tune golf 5 gti Post by: RaraK on January 25, 2013, 06:26:13 AM Many med9 ecu are instable during writing.

Maybe you are lucky? ;) I have failed a few flashes in my time, my tool was able to restart session if i did not power cycle or anything. just restart the flash right away and it usually goes. However, i would suggest unplugging the fuse for the fans before write! they can and will kick on sometimes during flash and it your charger is no good you are surely making a bad flash :) even if it did fail, i was able to write file on bdm(not the e2p, just flash) and was fine. Thus i have not seen it necessary to have a full backup, but for this guys scenario, i would have a full backup. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 25, 2013, 08:07:41 AM I think I am going to take a chance, if it fails I will deal with the issue and if anything I will learn along the route. Thanks for the cautions guys.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: terminator on January 25, 2013, 10:52:17 AM MPPS 13 is a fake clone.

Title: Re: moving onto med9, first time tune golf 5 gti Post by: technic on January 26, 2013, 03:19:10 PM I have a different opinon. Original MPPS has always been able to recover MED9 for me. I've done many tests on the bench with deimmoed version also. Same with EDC16.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: B234R on January 26, 2013, 03:30:11 PM I've also had good success with the original MPPS tool on MED9 so far.
I'm running the upgraded V16 version. My personal car is a MK5 GTI and I've programmed that car/ECU a lot over OBD. Every single programming worked the 1st time and 100% flawless so far. Even with different MPPS software versions. (I'm always running the latest update) Knock on wood. Title: Re: moving onto med9, first time tune golf 5 gti Post by: Rick on January 26, 2013, 03:37:07 PM Genuine MPPS is good on these.

Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on January 30, 2013, 03:40:15 AM I know on my 1.8T and the older version of vcds the fault on the post cat probe would be B1S2 so bank 1 sensor 2, not sure why it would reference bank 2 unless it an issue in vcds itself.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 02, 2013, 02:17:21 PM s3 intercooler installed on friday afternoon, been hesitant to try flashing with all the warnings from other members but I decided to give it a bash tonight.... first flash success! No issues!
It was a very basic tune (just to test flashing and checksum correction) LDRXN\ZK KFLDHBN KFMIRL really dont enjoy using vcds to log after being spoilt with me7logger :'( so I forgot to log RPM (of all things) but now that I feel a bit more confident about flashing this ecu the revisions will come quickly and so will the questions! Just a quick thank you to all the valuable members on this forum that have helped me, I still have a tremendous amount to learn. Title: Re: moving onto med9, first time tune golf 5 gti Post by: Rick on February 03, 2013, 04:22:54 PM Biggest pain is no emulation and 10min flash time!
Title: Re: moving onto med9, first time tune golf 5 gti Post by: prj on February 03, 2013, 04:57:34 PM Biggest pain is no emulation It's possible, just not in the conventional sense...But I'll talk when I have it working. Title: Re: moving onto med9, first time tune golf 5 gti Post by: Rick on February 03, 2013, 05:43:05 PM Sounds good mate, I currently have no working solution for emulation, would be nice to have someone sort it - they would be suitably rewarded lol!
Rick Title: Re: moving onto med9, first time tune golf 5 gti Post by: prj on February 03, 2013, 05:50:20 PM I'm getting there. Proper data logger first, emulation later.
Baby steps. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 03, 2013, 10:45:56 PM Biggest pain is no emulation and 10min flash time! Yup 10min flash time is a bit long but it works! Now to figure out why my first flash made the car feel down on power, power delivery etc was smooth but just felt weaker than with the stock file, flashed it back to stock for now while I make up a decent file. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 04, 2013, 10:08:26 AM ok so changed LDRXN/ZK, IRL/S, BHN did a few logged runs now but the WGDC seems weird to me...

Rick Yes, really interesting. Keep me posted also. @airtite - you are running way too rich... Title: Re: moving onto med9, first time tune golf 5 gti Post by: B234R on February 04, 2013, 04:15:29 PM Yes, too much boost, not enough timing and too rich.
Just my opinion, but K03s is a bottleneck. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 04, 2013, 10:37:13 PM not working on timing or fueling yet, read above only changed LDRXN/ZK, IRL/S, BHN all boost related. Once I have my boost dialed in I will move onto timing and fueling as long as its not running lean I am still on the safe side yes power will be down with it so rich.
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 06, 2013, 06:46:45 AM do these files have KFDLULS?
Anyone want to share their stg2+ ldrxn for these k03s turbos? Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 06, 2013, 09:57:54 AM KFDLULS 1CDF90?
All the tfsi ols I have dont seem to have KFDLULS defined? Title: Re: moving onto med9, first time tune golf 5 gti Post by: B234R on February 06, 2013, 11:35:49 AM There will be KLDLUL. 8x1.
Will look at your file later. Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 06, 2013, 11:52:15 AM There will be KLDLUL. 8x1. Will look at your file later. KLDLUL = 1CD218? axis at 1CD210? Negative deviation threshold for overcharging errors. So no KFDLULS in med9? In my me7 file I was told to FF KFDLULS so that I could work on my boost control without having any boost deviation codes interfere, would the same apply here but using KLDLUL are there any other maps in DLDR that I should address? Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 06, 2013, 11:07:10 PM feel like I am having to relearn everything again on this ecu :(
It doesnt look like TABGBTS is defined in any of the map packs I have? regarding ltft and stft logging, on the me7 I could look at block 32 in vcds but block 32 in vcds on this ecu only shows one fuel trim value? Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 06, 2013, 11:12:25 PM I see TABGBTS is TAVVKBTS in med9
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 07, 2013, 10:31:15 PM please can someone confirm
KLDLUL = 1CD218? axis at 1CD210? The axis values dont seem right? My definition has the axis as min*s isnt it meant to be hpa? Title: Re: moving onto med9, first time tune golf 5 gti Post by: RaraK on February 08, 2013, 01:49:10 PM its hpa
8x1 axis is before data in file. sometimes its 8 bit, sometimes 16 bit depending on image. Title: Re: moving onto med9, first time tune golf 5 gti Post by: SVSPORT on February 09, 2013, 09:17:58 AM please can someone confirm Yes it's 1CD218KLDLUL = 1CD218? axis at 1CD210?

Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 10, 2013, 03:52:36 AM something interesting I came across while comparing different mk5 gti software versions, not sure I correct I am but....
The ed30 gti which has the k04s turbo stock is running sw version 1K0907115T which has an identical map layout to 1K0907115R from a mk5 gti with k03s turbo but with the maps etc bumped up for the k04s so by comparing the 2 we should be able to see what differences the VW engineers have made to adjust for the higher boost levels etc.... I am trying to source a stock 1K0907115R file because the one I have has already been modified, then I will carry on creating my definition file and compare the 2 properly.

I did 2 logged runs again now and everything seems fine apart from fairly high EGTs which dont make much sense because the last lambda logs I did where showing the car running fairly rich, what else could be causing the high egts on a stock file? bear in mind it is 30degreesC here today.

I thought the ecu would have compensated for the extra boost by lowering WGDC to prevent any overboost conditions? Here is a 3rd gear run before the car went into limp, little concerned as to why the boost spikes so badly before the n75 comes in, any pointers on what I need to adjust to stop the spike (KFLDRL) ?

Regarding the Q2 term according to the wiki KFLDRQ2 - LDR PID Q2 (differential term) - adjust this to compensate for overshoot when your boost ramp meets requested. Increase it if you see a lot of overshoot. If you have undershoot, try increasing KFLDIMX first. Only decrease Q2 as a last resort. Would I increase the entire table or try and address the areas where my boost is spiking? What increments should I increase those values by?

Yes you are randomly copying. To do this right you must set fixed duty cycle and make pulls at 0, 10, 20 etc %. Then fill it all in a table and generate the KFLDRL and KFLDIMX maps from that. And your boost control will usually be perfect. Only if after this it's not working quite right do you need to touch P and D terms.

Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on February 22, 2013, 02:37:29 AM still a little confused ??? the wastegate must be doing something, have a look at this log before I loaded up the 0% duty cycle file. You can see the boost spike while wgdc is at 95% then wgdc drops and the boost also drops but accelerator pedal and throttle plate remain at 100% and the actual boost sort of follows what the n75 is doing. But then that doesnt explain the 0% duty cycle issue ???

Do this, see what you get and report please. This is a genuine BorgWarner turbocharger?

Do you think its necessary for me to even look at that though?

My first question would be why the desired boost is so nervous? Read/log issues or is the ECU actually behaving like this? It basically asks the turbo charger to be extremely unstable...?

What is the preload of the stock actuator/turbo compared to what you run now? If they differ, then having the wrong preload (and not adjust it in the software) will probably yield in boost control difficulties. I didnt bench test the preload of the actuator before installing the turbo so it could be the cause but if the actuator preload was off would the boost looked like it did in the n75 unplugged logs? Right now the car is feeling strong and if I do a WOT run in 3rd it revs the whole way but every now and then specially in the higher gears if I go WOT it will go into soft limp with a positive deviation code a quick key off and key on sorts that out, so the question is where do I go from here?

Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on March 06, 2013, 12:31:18 AM this is from the a4 ols that I have, but the map data doesnt correspond to rail pressure but if I move the address over one then I get values that do look correct to me. this is how it was defined.

The fueling is based on the RPM essentially, HPFP keeps up with ease at higher rpm, uprated HPFP can pump more fuel per stroke, so therefore can keep up at lower speeds. Stock HPFP is fine on bigger turbo applications when you have some lag involved.

I have fitted the RS4 pressure release valve and have fitted an autotec HPFP pin, now I believe I need to adjust the maps under hdprsol to cater for the autotec pin but I couldnt see anything directly related to that...
1. I need to adjust the rail pressure up to 130bar for the rs4 prv (KFPRSOL)? 2. I need to adjust for the autotech fpr? 3. I need to try and lower fuel consumption as the car is running really rich (LAMFA) but I am a little confused on LAMFA now because reading here, as LAMFA is only meant to be used to enrich and not lean out fueling? Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on April 18, 2013, 11:54:22 PM anyone?

NO you need to adjust it to what you need to adjust it to ;) i only need 125 bar on wilder stock turbo tunes for instance 2. Yes, look in hdrpsol like i told you, its right there in front of you, few maps to change 3. fueling is controlled just like me7 in this sense, look at your BTS maps, lots of these stock maps you will find to be very rich, lean them up a bit Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on May 02, 2013, 02:43:42 AM anyone able to tell me what map is at address 1CDD34 its a little bit after the Q2 pid map?
Title: Re: moving onto med9, first time tune golf 5 gti Post by: airtite on May 02, 2013, 03:40:55 AM also trying to figure out whats at address 1D9432
