Hello Folks, think this might be my first post on this forum. I'm not new to remapping, I have been remapping EDC15C2 for close to 8 years now, I have had results that not many others have been able to reprodue. :)

..but the Diesel is sold and I have bought an Opel Insignia 1.6T instead. As far as I have found out it's an ME7.6.4.
Now I want ot remap it myself, it will be a fairly simple Stage1 tune with a decat (only the first cat, not the seond.)

I have a Damos for the ME7.5, I'm using this as a basis for defining the maps in the ME 7.6.4. This is where I need assistance from you guys. :)

I'm not looking for a cookbook recipe on how to make a stage 2, but I'd like to get some hints and critique on my progress.

This is my ori: [I HAVE REMOVED IT, IT WAS A TUNEFILE!]

I *think* I have some of the maps needed identified, can anybody verify?

- LDRXN 16x1 @ A6342 (Max specified load, this can roughly be translated into a boostcurve? (10xvalue+300-Atmos pressure). max is around 155, this gives me about 1.8bar absolute pressure. Correct?
- KFLDHBN 8x8 @ A14FA (Boostpressure limiter from atmospheric pressure? What are the axis, atmos pressure and rpm?)
- NFSM 6x1 @ A16F8. (Idle speed when rolling in gear? Axis is coolant temperature?)
- NLLM 6x1 @ A16FE (idle when stationary, no gear? Axis is coolant temperature?)

Now I have what seems like 6 KFPED maps
@ 9D73C
@ 9D8BC
@ 9DA3C
@ 9DBBC
@ 9DD3C
@ 9DEBC

Is it one per gear? They have the same values all 6 of them. Or is some of them for AT and some for MT? What is output of these, I thought it was load, but using 0,003052 as factor and max I get in the maps is ~105

-KFMIOP 11x16 @ 9D1E8 (is output engine efficiency in percent?)
-KFMIRL 16x16 @ 9C84A
-KFWDKMSN 6x16 @ 9C6AA (Throttle angle map)
-KFMSNWDK 6x16 @ 9C04E
-KFMLDMX 9x8 @ 9BEEA (max airflow though MAF?)
-KFZWMS 16x12 @ 99FB5 (Latest allowed ignition angle?)
-KFZWOP 11x16 @ 990C5 (optimal ignition angle)
-LAMFA 6x15 @ A5075 (Y axis is rpm, but what about the X-axis? Seems axis's are defined just in front of the map, but the X-axis does not make much sense to me)


These I'm more unsure of:
KFTATM? 8x8 @ A03DF (EGT model map, used for the EGT model?)
KFTATM? 8x8 @ A049D (EGT model map, used for the EGT model?)

I know that not all of the above are needed for a stage1 tune, but this is what I have been able to find so far. What do I more need to look for, for a simple stage1 tune?
The enrichment map when over the EGT limit (I cannot remember the name of it..)

I hope you are willing to point me in the right direction, not a lot of information on the ME7.6.4. :/

The enrichment map when over the EGT limit is KFLBTS A0EFE 16x12

LAMFA A5076
x-axis = KFPED values.

Lamfa is using requested torque not Pedal Position!
mrfa_w {DriverRequestedRelTorque}

Sorry for correction terminator :D

Forget it!  ;D

Ahh, I had it defiend @ A5075 - the req. torque axis did look a bit "off". :)

I have a few more. :)

I'm unsure of the two here, they are max and min flow through MAF - but why are they so far apart? I would have thought they would be close to each other?

-KFMLDMN 9x8 @ A4670
-KFMLDMX 9x8 @ 9BEEA

-KFLDRL 10x16 @ A64B4 (is this the "Wastegate DutyCycle map"? The map that is the precontrol value for the LDR PID?)

-KFLDIMX 8x16 @ A6362
-KFRI 6x7 @ A219D
-KFRP 6x7 @ A21C7

...Now this is a map that I anticipate to use to limit the torque in the lower gears.
-KFFRTMKI 8x6 @ A1961 (is the outout the factor to multiply with the requested torque?) (Oviously values above 1 does not make sense)

-LAMLGMTM 12x1 @ A1082 (The lean limit?)
-KFLBTS 12x16 @ A0EFE (This can be used to lower the lambda when EGT is over a given setpoint?)
-KFLF 16x12 @ A0A97 (Lambda at partload, can this be manipulated to give a slightly leaner burn during cruise? or is this a bad idea?)
-FZWSTNM 6x1 @ 9E97D (ignition angle during start?)

Now some values I *think* can be "abused" to prevent catalytic diagnose..

-TMSUKTD 1x1 @ A0567
Now std. this is -10.5 degrees C. If I raise this to eg. 120, will it prevent catdiagnose when engine temp during start is less than 120 ?

-TMNKATT 1x1 @ A0566
If this is raised to eg. 1200, will it prevent the cat diagnose being performed with a tester?

-TMINKAT 1x1 @ A0565
If this is raised to eg. 1200, will it prevent the cat diagnose being performed while driving?

-TMAXKAT 1x1 @ A0564
What happens if this is set lower than TMINKAT? I suppose the ecu gets quite upset.. Could the catmonitoring be "disabled" by setting max to eg. 100 and lower to 98 ?

-RLKTDHB 1x1 @  A0563
Maximum load for cat diagnose? what is I set this to 10 ? Will it prevent cat diagnose @ loads above 10 ?

I know the above is not the "right" way of disabling the cat monitoring/diagnose - but I'd like to keep the second lambda sensor in place and have everything look "normal" on a tester. Am I barking up the wrong tree here?

KFLDRL is POST PID Linearization of N75 DC %
KFLBTS is exactly what you say as long as KFLBTS is lower than LAMFA
EGT setpoint should be something like TABGTS or something
KFLF as  lot of people say is not used any more or people dont use it .I have found KFLF in older motronics too but
ther was no LAMFA

Okay, so the KFLDRL is some sort of "linearisation" of the Wastegate/Turbo? Interesting :)

Now I have been comparing my ori to an "OPC" ori from an Opel Corsa. The OPC corsa produces 192BHp whereas mine produces 180Bhp.

Now looking at LDRXN I would expect the higher powered ori to have the highest values - but it's the opposite way 'round.. Max load on the OPC is ~144 and on mine it's ~155.

I know that the OPC runs higher boost, so why is max allowed load lower on it?

in KFLDIMX I can see why the OPC makes boost slightly sooner, and makes more boost at higher revs. That maps is as I'd expect, with higher DC low down and top end. (in the middle area, it's slightly lower approx. by 3%.

But why is LDRXN lower?

I'm quite surprised at this having LDRXN, as the ME1.5.5 in the Astra from 2002-2004 has LDRXN like ME7. Then on the VXR's Corsa and Astra (ME7.6.2) they used KFRLSNT. Now the insignia seems to have gone back to having LDRXN.

Either way making a nice little Stage 1/2 should't be no issue with this ECU provided you got a fair amount of S4 wiki maps listed on it.

Maybe you didnt find LDRXN but LDRXNZK on the OPC map or something .They are back to back and they have similar values.
LDRXZK is always lower.

I dont know about opels but VAGs have different LDRXN indeed.
the QN- RP (150-180hp) differnces in LDRXN are

150 hp: 95   102   126   132   131   129   127   118   128   123   124   117   110   106   103   97

180hp:  90   108   122   131   135   133   132   131   127   125   126   128   134   124   119   114

with the same KFMIRL KFLDRL KFLDIMX

These ECUs usually have KFMDMXNT and RLSMDN....

This is (what I believe) is the LDXRN on both:


(http://catcams.dk/LDRXN.JPG)

They are at the same place (albeit different ddresses, due to the different layout).

Now if the OPC has a better flowing turbo (bigger), the filling will be better, and thus the load will be lower? Can that explain why it is lower on the OPC?

None of those are defined in the 7.6.2 damos I'm comparing with. :/

Also your file isn't even stock to begin with.

hmm.. The insignia file is not an ori?? It should be an ori, not a modified one. :/

Do you have the ori that goes with it?

Iamwhoiam?

Hmm no answer. OK I'll continue with my mapfinding then.

The file comes from a well respected tuner, I highly doubt that he would send me a tuned file as an ori. But you never know I guess.
I do not - yet - have the tool to read the file from _my_ car so for now I have to rely on the ori given to me by my mate.

However, I had the car on the rollers yesterday, and by the looks of it - it is remapped allready. The way the car behaves and drives leaves a lot to be desired.
I do not have any logs yet, so all I can show it the rr print.

Now something fishy is goint on above 5600 rpm where it suddently looses it's "oomph". :/

Ask your respected tuner friend what his EVC customer number is please :)

Because of the OLS screenshots I posted earlier? Have you ever heard of a demo version?

(http://catcams.dk/evc_demo.JPG)

My mate does not use OLS, _I_ use it to find maps as it is the absolutely best tool for the job.

Once I have my maps defined I convert the ols to a TunerPro MapPack

Now that you have had your free (failed) punch at me, now le't focus on the issue here...

You say the file is not an ori, I ask you why you do not think it is an ori? Do you have a genuine ori to compare it to, or are you just talking out your arse?

I asked my mate for an Insignia ori, and this is what I got..

I don't have an original to compare it to, but most original files don't have checksum errors.

Also, can you upload your files here from now on? Redirecting to sites with invalid security credentials scares me :P

Ahh! I do not have any ways of correcting the checksum, nor check that it is valid. That explains why I didn't notice then.
Bugger, better start looking for a proper ori file then. :/



Ahh yes, sorry about that. It uses a self signed certificate, and since it's my own server I have the certificate added to my computer, so i do not see the certificate issues.
Sorry about that. I'll upload it to another non https server.

You can upload them here.

Let's not start that here please... There's enough of these kind of posts on chiptuners.org


You should also avoid hosting your own pictures and posting them here.  They don't show up and it's very annoying.  SSL is cool and all, but not needed for things like this.

Host your pictures and files elsewhere, disable SSL, or attach them to your posts using the forum software please.

Thanks

Soory about that, didn't think about it properly. :/

Images moved to a non ssl server, I hope they show up now?

I have just received two other "ori's" now and I have done a quick comparing with the previous "ori" I had..

In the original the following maps were changed..

-KFMLDMX
-KFMIRL
-KFMIOP
-KFATMKR
-LDRXN
-KFPED
-KFZWOP
-KFZW

..along with some others I have not yet identified. :/

I wonder where my mate got that "ori" from  :-\

Yes everything seems to be working now.

Thanks!

The reason why I asked is because there is such a number in the file, where a NOREAD tag would be located too, but that one isn't there. Only a 5 digit number that looks like an EVC customer number :)

Please post the ori!

This is what I have as an original

here is the ori. (Seems it's the same as IAmWhoIAm just posted)

I have been digging a bit more.

Why hasthe tuner changed UADPUMX ? Does not make sense to me? Because they want to be able run right at the limit of the sensor??

Also KFZWOP - that only makes a difference to the calculated torque right?

KFSZT - Ignition coil charge time? INcreasing this helps the coil get enough energy to give a stronger spark?

By the looks of it they have "disabled" the Katdiagnose by setting NDKTSO and NDKTSOT to 80 rpm?

Also KFLBTS is set leaner than std. I have been told that is is on the rich side in ori trim, does it make sense to make it a bit leaner to get more power in this map?
Where it is not 14.7 is has been leaned out by ~0.68 AFR. ..But LAMFA has been reduced to give lower AFR, just as I'd expect it to.
