Default Increase Imax fault limit to prevent upgraded fuel pump warning - 08-30-2016, 08:20 PM

For anyone with a E series N55, stage 2 or 3 fuel pump and a EKPM60_3.C13 module.
If you are recieving a fuel pump control current too high warning you can load this file using NCS-EXPERT and NCS DUMMY to eliminate the fault light. The data that has been changed is the max current fault limit and the updated checksum.
Using NCS DUMMY and the attached file, check the wert200 box for all 6 functions and then load it into the EKPM60_3.C13 module using NCS-EXPERT.

Updated

With the EKPM60_3 Imax.C13 file in the C:\NCSEXPER\DATEN\E89 folder follow the steps listed

1. Launch NCS Expert. At this moment no profile is loaded, so the screen is quite empty.
2. From the "File" menu, choose "Load Profil".
3. In the "Choose profile" dialog box, select "NCS Dummy profile" and click "OK". Nothing much
happens, but you'll notice some of the buttons on the bottom now have labels.
4. Click the "VIN/ZCS/FA" button (F1). The button labels change once again.
5. Click the "ZCS/FA f. ECU" button (F3).
6. In the "Choose CHASSIS" dialog box, select your chassis and click "OK".
7. In the "Choose ECU" dialog box, select one of the presented modules (for example "CAS") and click "OK".
8. After a short moment, the top groupbox should now show information regarding your car.
9. Click the "Back" button (F6). The middle groupbox now shows the available modules and default job
name.
10. Click the "Process ECU" button (F4).
11. In the "Choose ECU" dialog box, select the desired module (EKP) and click "OK". Make sure the
NETTODAT.MAN manipulation file is for the same module.
12. Click the "Basic functions" button (F5).
13. In the "Choose basic function" dialog box, select "coapiCodeSgByNettoData" and click "OK".
14. In the following "coapiCodeSgByNettoData" dialog box, make sure the correct module is set for "CBD
name"(EKPM60_3 Imax.C13) and enter NETTODAT.MAN for "Nettodatenliste". Click "OK" to begin the nettodata coding job.

The module has been coded! Please note that some modules require the ignition to be switched off and on
before the changes take effect. If you are happy with the result, keep a backup of NETTODAT.MAN for future
reference.

If you continue to have problems you can manually add the new data yourself by opening NCS for Dummies go to EKPM60_C13 right click and add a new parameter for each of the keywords.
Copy and paste the data in the new parameters.

this is 2 data points too long. I removed the last 2 and when I went to code the modified data in it said my new parameter was faulty. the only one that started out red in ncs dummy was the one above.

Decode the file I provided .c13 read the wert 200 values and implement them as described above, sorry I was at really busy at work when I posted the previous message. All the data above is copied from the original settings except the fault and Checksum. Are u in SA TX?

Then under module funtions click update Module

I'm interested to know what exactly those parameters and values mean and how they're checksummed out of interest. I have an N54 and am getting 2aae shadow code (even though it's disabled in the DME flash) as well as yellow exclamation mark on the dash on and off while driving since fitting a Stage 2 LPFP. After a bit of searching, it seems that everybody with this issue has just come to accept it but I want it gone.

The four bytes in fault limits are max voltage, min voltage, max current, min current. The checksum is a CRC-16/CCITT-FALSE.

Thanks. Why does it also need new values for characteristic curves, functions and pump parameters?

Ah yep so something like this (probably factors of 10):

Max Voltage - AA - 160 - 16.0V
Min Voltage - 45 - 69 - 6.9V
Max Current - B4 - 180 - 18A
Min Current - 2F - 47 - 4.7A

That would explain why my warning comes and goes, because it's right on the edge of the current limit. This page shows the Walbro uses around 18a @ 80psi:

http://www.radiumauto.com/Blog/Post/...-Pump-Test-100

I wouldn't trust the wiring for any more than 22A. I'm thinking I'll change the 3rd byte to DC (220. 22A)

If I tell you the characteristic curves, functions, modified fault limits and pump parameters that apply to my N54 car, would you be able to give me the checksum for it?

Fixed for N54!

Thanks torr! The stock N55 coding that torr's changes are based on are different to my stock coding on my Euro E90 LCI 335i N54.

To calculate the checksum, you put all the Hex numbers from the coding that applies to you for each section in the order that they appear in NCS Dummy (except checksum), get rid of all the commas and join them all together into one big string. Chuck the string into this checksum calculator and choose input type as hex. The "CRC-CCITT (0xFFFF)" result is your checksum. **Verify that you're doing it correctly by using stock values and making sure it comes back with the stock checksum first**.

I ended up using a 21A limit but I'm tempted to do again at 19.5A so that if the fuel filter becomes quite clogged, it will cause more pressure at the pump, drawing more power and flagging the error. That'd be handy to know when you need to change the fuel filter. Also I'm pretty sure the EKP can only handle 20A anyway and the fuel pump fuse is 20A.

I'll do up a guide soo as I know there are a few N54 owners with this issue. Maybe only E90 LCI vehicles use the EKPM3 and everything else uses the EKPM2 because most don't have this issue.

bradsm87,
Im glad you got it sorted out and on your own. Cheers

FYI:
MAXIMUM FUEL PUMP MOTOR VOLTAGE [VOLTAGE_V=(DATA*23)/1023]
So, AA=170=3.822091887V
and 45=69=1.551319648

And if you interested here are a few of the CHARACTERISTIC CURVE.

I saw that conversion formula used for the EKPM2 coding which looks completely different to the EKPM3 coding. 3.82V doesn't seem right unless it's referring to voltage drop but i sorta doubt it.

Do you think the axis on the characteristic curves mean? One looks like RPM. Not sure about the other.

The CC graphs are pump speed vs Liters/hour and liters/hour is scaled, 0-245 to the pumps output.

Hello Guys,

does anybody have the File for the N54 ? I wrote bradsm87 but he didnt answered, so the last chance to fix my Walbro 455 Problem is, to get this File :/.

Thanks !

Sorry I got your PM when I was out then completely forgot by the time I got home. The file is on my home computer and I'm away until Tuesday so will grab it as soon as I get home. Sorry again for forgetting!

I ended up finding the file on my laptop. I don't know what's going on with my EKPM60_3.C13 file but when I now try and open it on ncsdummy, I get an "Unknown Parameter Keyword" error. I've kinda forgotten pretty much everything about this since I did it so I'll have to refresh my memory. I'll have a play with it and report back.
