Thank you for the files. the edc15c doc and the 3.0 tdi a2l was new to me. thank you very much for that!!

It turns out the 3.0 TDi V6 DAMOS was one of the few posted up here in any case:t

This thread was split off from this original thread: http://nefariousmotorsports.com/forum/index.php/topic,745.0.html

In the attached,

does anyone know what the proper map names are for the popular tuning maps:

Drivers wish, SOI/BOI, Torque limiter, Duration map etc etc?

Rick

Which file did you mean exactly?
I can help :)

Thanks for the info, Doug!

Hi cam I would like to know what the names of common maps, such as drivers requested torque, smoke limiter, torque limiter, start of injection,  are in the documents posted above.

Rick

How about you just read it all and translate it and then share it with us? I'd like to know too :)

I can translate basics of course :) I will do tonight, ok?

Thanks Cam.

It's the torque control modules I'm interested in mainly.

Rick

Yesterday was server down, i will work on it tonight ...

Basic fueling in EDC15

For basic tune-up you need modify following:
Driver wish = Fahrverhaltenkennfeld (mrwFVH_KF)
Smoke map = BEG Rauchbegrenzungs kennfeld (mrwBRA0KR)
Torque map = BEG Drehmomentbegrenzung (mrwBDB_KF)

Function of injection quantity is driver wish (Fahrverhaltenkennfeld mrwFVH_KF) -> torque map -> smoke map -> engine

Smoke map depends on mass air flow sensor (MAF).
Torque map depends on atmosphere pressure.

Don't forget to add correspond amount of air! Otherwise black smoke will go from exhaust.

Turbo pressure modify:

Turbo pressure demand = LDR Sollwert-Grundkennfeld (ldwSWBGKF)
Turbo pressure limiter = Max.wertekennlinie (ldwMXWKF)
Turbo pressure single limiter = LDR untere absolute Sollwertgrenze (ldwSWBLDMX)

Function is demand -> limiter -> single limiter

I hope that will be helpfull for others newbies in diesels and still working on translating but diesels are very simple to remap ...

Hi cam.

Thanks for that. I'm interested in diesel remapping (theoretically at least). I would like to remap our Toyota D4-D 116 PS but the Denso ECU has a high level of rolling encryption (so I'm led to believe) thus a physical kit is needed, worse luck.

TTQS

Yes, Diesel remap is very simple

Can you post the EDC16 translation please?  I think I have found most of it.

Rick

are you sure about that encryption?
at least the denso ecu of subaru boxer diesel with 110kw seems to be quite straight forward and similar to bosch edc16 ecus.

No, I'm not sure, I'm just quoting from a guy who works for the people in the link below coupled with the fact that nobody anywhere offers Toyota D4D software remaps. Instead, hardware kits are sold which intercept the fuelling and alter it (I think). Result is 116 bhp to 139 bhp and 207 lbft to about 250 lbft for my engine so worth having, I guess but my wife isn't bothered!

http://www.lindoptoyota.co.uk/component/content/article/67.html

I suspect it is true for the following reason: Toyota make extremely durable and reliable cars and are almost certain to not want anyone to affect that by altering the ECU parameters, so have specified a high level of encryption from Denso. However, Subarus are very popular cars for tuning on the aftermarket and I'm sure that Fuji Heavy Industries are very keen to capitalise on the cult status of Subaru Imprezas, etc. from all that WRC success by making their cars easy to modify/tune/remap  ;)

TTQS

I don't know much about the Denso ecu's mounted on Toyota but Denso's mounted on Mazda use RSA for protection when read by OBD.

I'm an IT layman. What's RSA?

Does that mean that generally, encryption is only applied when the ECU code is read over OBDII? I.e. if you flash off the code in boot mode (if possible on the Denso ECUs) then the encryption will be 'bypassed'?

TTQS

http://en.wikipedia.org/wiki/RSA

Flashing with boot mode would not require having the RSA keys to flash. If there is any checking of integrity of image by the ECU (checksums or digital signature) then you still need to fix that.

That's how everyone is doing MED17 now.

In the case of Denso ecu's used on Mazda the cpu is a Renesas SH7058 and looking at the datasheet I haven't seen anything about internal encryption so I believe that RSA is applied when working over OBD. The cpu has 4 default modes for flash access described in the datasheet and non seem to talk about encryption:

- Boot mode
- User Program Mode
- User Boot Mode
- Programmer Mode

On my spare time I have done some tests on this ecu to try and read flash content and added hardware support on my current work in progress hand held programmer. I'm currently waiting to receive the PCB I sent out for printing.

I've attached a picture of the boot mode connections necessary for interfacing to the ecu.

OLS for EDC16 in first post is not good not right address!

Basic fueling in EDC16

For basic tune-up you need modify following:

Driver wish = x.Gang (voreilendes) Zugwunschmoment aus Motor-Drehzahl und AccPed_rChkdVal (resp. APPCD_rAPP1UnFlt) (AccPed_trqEngx_GMAP)
Driver wish = Gruppenkennfeld für AWD (AccPed_trqEng0_GMAP)

Smoke map = Rauchkennfeld (FlMng_qAFSCDSmoke_MAP)
Torque map = Motorschutz Mengenbegrenzung durch Atmosphärendruck (EngPrt_qLimP_MAP)

Function of injection quantity is driver wish -> torque map -> smoke map -> engine

Smoke map depends on mass air flow sensor (MAF).
Torque map depends on atmosphere pressure.

Don't forget to add correspond amount of air! Otherwise black smoke will go from exhaust.

Turbo pressure modify:

Turbo pressure demand = Kennfeld für die Grundwertbestimmung des Ladedruckbasissollwerts (PCR_pBDesBas_MAP)
Turbo pressure limiter = Größter erlaubter Ladedrucksollwert in Abhängigkeit vom Luftdruck (PCR_pBDesMaxAP_MAP)
Turbo pressure single limiter = Größter erlaubter Ladedrucksollwert (PCR_pBDesMax_C)

Function is demand -> limiter -> single limiter

Hi,
Denso ecu is very different from others, but reading and writing (and encryption while process) possibilities is depends on tool which you use. Some ecus have 29F400 flash memory but newest are still difficult to read/write and just few tools can do that. Remapping is not too difficult (few maps for basic working remap).

I can make tutorial for EDC15 and EDC16 ecu remaps if is interesting :)
Please tell me if you interested and i will make that with example files :)

Very interested, cam.

Reasonable guides on EC15 & EDC16 tuning can be found here:

http://www.ecuconnections.com/forum/viewtopic.php?f=2&t=867

TTQS

For basic dependencies good :)

Still making examples - not many free time now :(

Hi cam.

I would be interested in an EDC tutorial with examples. Timescales aren't a problem because I won't have much time to study it until early next year. I would rather you took your time and produced a clear guide than knock something rough and ready out.

Regards.

Doug

Hi Cam,
Also interested in an EDC16guide.

Thanks

this is not quite right.
most important TL are rpm based.
There is also an athmospheric correction map that delivers percent of max allows, but this can and should be untouched IMO.
Also you show think about reducing EGR and/or SOI or raise Railpressure in order to not extending the burning time to much after.
But this depends on overall injection time and amount of tuning.

Yes, but now we talking about basic remap ... ;)

EDC15 is pretty easy...

Specially for basic remap.

any can provide an edc17 funktionsrahmen or any different edc16,med9 etc. than currently available here?

additionally I can provide support for edc16 remaps as I did a lot in the meantime and am quite familiar with it now.

Ha yep, I`ve been tuning engines over 3 years for oem manufacturer (EDC17 cartronic) and can say it's not that easy if we really get into tuning.. :)

There is more than just max amount of fuel, max boost.

I would like to remap p1,m1, p2 injections (this will allow a higher amount of fuel to be burned in the same time window with less rapid pressure rise in cylinder), calibrate bigger injectors etc.

But now I'm talking about serious power mods and not the usual what can you get swith stock equipment.

Also this would include modifications to OBD system checks and taking out the PDF  and so on..

And I still have 4.years of the NDA agremeent left..too bad. :(

Hi,

does anybody have the (updated) English version of EDC16 documentation that can be downloaded from here?
http://www.doc88.com/p-376167883039.html

 Hi,
    maybe this is also interesting

can somebody tell me what these annoying sh** posts are?
I really love to read the technical discussiuons which have mostly high level. I hope that the number of  such posts will not increase...

Hi,
this is my first post here. Thanks for the documentation "EDC15/16 Funktionsrahmen" in german.
I'm an newbie in the tuner szene. I'm only interested for tuning on my own car - is a FIAT Ducato 2,8 jTD (128HP).  This is a RV (Motohome).
Two years ago i'm beginning with the first "tuning" on my car.
My Equipment is:
-Galetto
-WinOLS with the OLS235_Bosch_EDC15 C2_CR2.dll
Now the is Car running well  :D
Today i have a problem: after 40000km is my second clutch over.  >:(
Just i like to remap my ECU. I think that my Torque is too high ?

regards

Well, what did you write into the ECU the first time around?
And yes, it is possible that the mapped torque is too high for the clutch.

Hi prj,
Thank you for your answer.
Four years ago, I began my involvement with ecu's. I had since bought another camper. The engine (2.8 JTD common rail) of FIAT has strong power fluctuations. My engine was definitely a "weak".
My turbo is not a VTG-Turbo, i have a contantly pressure (about 1 bar)
It took two years for me to acquire a basic knowledge of tuning. One finds no one helps one. :(
After I tuned my maps amateurish , I was very proud that the engine was running so well.  :D Now I drive two years with this "tuning".
After 10000km the clutch slipped on the 5th Transition. I let them go. (The car is second hand)  After 16000km sometimes it slips again. This is not normal.  >:(
Therefore, I am now seeking further literature to only once to identify the characteristic maps. Maybe me the literature from here (EDC15/16 Funktionsrahmen) can help?
Very nice it would be if one of you pros could actually take a look at my tuned file , and could give me some helpful tips. I don't need stupid comments, I know myself that I'm just a beginner.
I can even attach my original and the tuned file, or is not welcome here?
As I said, I do it for myself, and not professional. Of course I could buy a professional-tuned file, but it is interesting to me, and i also learn something along the way.

Sorry for the bad english, i'm german.

Better create a separate topic.
And better not to attach your file, but attach a list of the maps you changed, and why you changed them.

Maybe good to post locations of the maps as well.
I don't know how it is with others, but personally I don't feel like looking through and comparing binaries, and defining the maps.
It's very easy on EDC15, but still waste of time.

At least show the basic maps you changed and how much - torque limiter, smoke limiter, drivers wish.

Would have been nice to have an english version of "EDC 15+ Funktionsbeschreibung P12 - VG2" and "EDC 15C Funktionsbeschreibung B079.CC0"

But i am interested in how to change settings besides MAP's. Does anybody know how to eliminate transmission?

Yes, hold the brake and gas at the same time and wait until time does it's job.

Hey,

is it possible to do RSA using winols for the edc15p+  ?

Could someone please help me with this or point me in the right direction :)

thanks

Ok, so I tried this and the trans is still there. Car will not move now in any gears tho  ??? ??? ??? Should I make a log?

Great post !

Thanks to all for sharing.

Here you have an english versión for EDC15+ that someone translated doing OCR work.

Not very good quality but perhaps helps someone.
