Nanocom- I think we have a problem

[discv]

I have yet to find anyone who has mastered the injector code issue using nanocom.
Testbook accepts the five digits stamped on the injector.
Nanocom reads [e.g] NG GB 3GA. 7 digits.

And nanocom will not respond to any questions on this.

Confusing!!!!!VERY confusing
i've realised that before with the V2.04 i had diffrent reading compared to new V2.05?
and i swear i havn't touched any settings......
Before After
INJECTOR1: LC LH 2-F-B INJECTOR1: LC LH 2-F-C
INJECTOR2: NE NC 0-M-C INJECTOR2: NE NC 0-M-A
INJECTOR3: LG NL 0-M-C INJECTOR3: LG NL 0-M-A
INJECTOR4: NM ND 0-M-C INJECTOR4: NM ND 0-M-A
INJECTOR5: LH NE 0-M-C INJECTOR5: LH NE 0-M-A

The only thing that changes is the last Letter BUT still 7 digits
Has anyone else had the same Problems?
Cheers

I think these changes are one of the issues addressed in V2.05.
It is only a small change. Your 5 digit code has not altered.
Your No1 injector will be stamped LCLHF.
So far as I can make out, if you were reinstalling this injector, you would enter LC in the first box- LH in the second box- and now it gets hazy.
I think you only enter one digit in the third. Not sure if it is 'F' or if you substitute this for a '2'.
I think that Nanocom then modifies that single entry to a 7 digit code.

thats the way it worked for me when i checked my codes

There are 3 types of injectors - it should allow you to enter what is stamped (single alpha/numeric character) then convert for the others

If all my theories to date are correct, I think that your list is the wrong way round.
I believe that the first column of codes is the correct/latest version.
If I am right- I've got the answers. And it is soooo simple.

[bluerazor]

Nooop It's this way round before & After update
This i can say for sure because i created a folder before and after
The first row dated back 14/05/2009 with V2.04 and the second row 13/06/2009 with V2.05 firmware.
I know it's confusing

Thanks for confirming what I thought. There is a problem with V2.05.
And Nanocom will not reply about this.
Your first column of readings makes sense- the 2nd is wrong.
Have you, by chance, got a record of the 5 digit code stamped on your injectors. [Not what Nanocom says]
Tony

[discv]

Bluerazor, Changed my mind! I'll tell YOU your five no. alpha/numeric codes.

Injector 1 LCLHF
2 NENCM
3 LGNLM
4 NMNDM
5 LHNEM
Why have I done come up with this?
Well unless there are 2 Bluerazors -your Italian might get me a response from Nanocom- and I need your help!
Tony

[bluerazor]

Ok I will contact Mattia "Nanocom for explanations"
I'll keep you informed.

Thanks. In the mean time refer to my post for some answers to your question. Saves me writing it all again.

Nanocom and injector codes. Answers. - Land Rover UK Forums

[LandyAndy]

Hi
The "A" coding was what I was told to do to my injector readings by my ECU upgrade supplier.
A code tells the injector to squirt a fine mist before the main shot.
My Nanocom with the 04 update would not let me write the A code,it always remained at C code.
My suplier tells me A is the way and need it to make my tune work correctly.
Now my Nannycom is caput as a result of trying to install the 05 upgrade I will need to get the new ECU coded using the supliers Autologic.ANOTHER TRIP TO THE BIG SMOKE:mad::mad::mad:

Hi Tony
I followed your link,but couldnt post as Im not a member.
See my previous post.A code is what you want,it delivers a fine pre-squirt of diesel to improve performance.Perhaps Nanocom have added it to suit Euro3 TD5s????

Have followed your post with interest. But something is wrong!
You cannot edit the 3 entries in the 3rd box on Nanocom.
They are tied together at the hip.
You may think you have changed something- but try re reading the codes.
For example, if you have a type 1 black top injector, 5th character C-
Nanocom will or should read 0-M-C.
This cannot be changed to 0-M-A.
I stand to be corrected!

Hi Everyone
Finally i managed to contact Mattia from "Nanocom"
Here is the answer Re: Injector Codes
Ciao,
Se usi il computer solamente le 5 cifre realmente scritte nel iniettore,altrimenti in standalone, noterai che le ultime 3 cifre variano assieme e dovrai trovare la combinazione che contiene l'ultima cifra del tuo iniettore non importa sia essa la prima la seconda o la terza delle 3.Questo perchè esistono 3 diverse serie di iniettori che variano solamente nell'ultima cifra

If you use the PC consider only the first five figures which are also shown on the injector, instead when in Standalone you will notice the last three figures changing all together, here you will need
To find the correct combination that corisponds to the last figure of your injector it makes no difference whether it’s the first,second or third figure This because there are Only Three types of Injectors that only the last figure changes

[discv]

Bluerazor, I seem to be following you round the world!
You seem to be able to get Mattia to reply.
Could you ask for comment on these 2 points:
1/ Nanocom is showing a code NG GB 3-G-A. An impossible code.

2/ Nanocom is showing no change in voltage on track 3 of the throttle with the engine running. That's on any car I have tried.

Thanks Tony

[bluerazor]

Hi Tony
I will try to contact Mattia for the Throttle issue...
Re: The injector codes don't be confused CONSIDER only the first Five readings
The last two figures are the Series "like Mattia explained there are ONLY three Injector Types on the market and are defined by these last figues/letters
Hope it's a little clear now

Vince, trust me NG GB 3-G-A is an impossible code.
The injector is stamped NGGBG. This should read NG GB 3-G-C.

This translation that the first 5 characters should match the injector is not correct. However, it would be true in the case of a type 3 injector.
I have type 2. Therefore the 6th character applies.

[bluerazor]

Hi This is what Mattia "Nanocom" wrote
To make things clear, there are three Existing types of Injectors fitted on TD5 Engine’s.
In the ECU it contains the same standard binary coding, although Alfanumeric codes have changed within these years
The First series had the last figures A-B-C-A with repect to 0 or 3-1-2. Subsequently these
Values where expessed directly in numeric from 0 to 8 and in the later generation indicated
With the following letters M E F G H J K L M the same as the numbers from 0 to 8. Therefor
An injector stored in the ECU with the third figure “3” would show up as follows depending on the
Injector type
NG GB A
NG GB 3
NG GB G

Nanocom so as to not make mistakes it writes all three together
NG GB 3-G-A cioè NG GB 3 or G or A

Up to Firmware V2.04 this was wrong with the first series Now fixed and checked with V2.05.
I’ve just noticed that the Manual is wrong it still shows the correspondence ABCA Wrong,
It should be CABC.


Accelerator Readings
The third track reading I’ve checked and works correctly, the only thing I point out is this is valid for euro3 models which have three wire accelerators, vehicles before 2002 don’t have the third wire therefore receives a false interference reading generate by the potentiometer.

[LandyAndy]

We seem to have 2 issues.
What the code is and Nannocom reads.
My ECU upgrade suplier DEFINATELY states A codes MUST be used with the upgrade,no matter what code they are stamped as.A code tells the injector motor to give a mist burst before the main squirt.
My Nanocom died with the latest upgrade so I will be getting my supplier to instal my new upgraded ECU when I go up to Perth next friday.
Will have another chat and let you know.

From Rovacom docs:
==============

Injector Grades 1 to 5: This is a 5 digit value which tells the TD5 ECU what grades have been assigned to each injector when it was tested at the factory after manufacture. The TD5 ECU then uses these values to compensate the fuelling in direct relation to the tolerances of the injectors fitted to each cylinder. The first two digits are an offset for the start of injection from nominal within the range of plus or minus .000127 seconds, the second two digits are the same as the first but for the end of injection and the last digit is a measured variance in idle performance.

If the Injector grades are lost or unknown it is possible to read them directly from the injectors themselves as the letters are stamped on the top face of their aluminium cover. However, to access the injectors, it is required to first remove the cam cover. When a code is read from an injector it is actually 5 letters you will get, but due to a change in the letter scheme used on later vehicles, for the last letter which actually has overlapping numerical values, we have chosen to show the real numerical value stored in the TD5 ECU to give our users the ability to program correctly in both schemes.

The valid values for the first digit are: A, B, C, D, E, F, G, H, J, K, L, M and N.
The valid values for the second digit are: B, C, D, E, F, G, H, L, M and N.
The valid values for the third digit are: A, B, C, D, E, F, G, H, J, K, L, M and N.
The valid values for the forth digit are: B, C, D, E, F, G, H, L, M and N.

Please be aware that the value you read with the Vehicle Server and then display is the actual numerical value which is stored in the ECU.
To translate the Alpha code value into the correct numerical value the following conversion can be used:

For scheme 1 (earlier - the early ECU would not store a value higher then 3)
A = 0 or 3
B = 1
C = 2

It should be noted that with the Rovacom Lite/Pro unit it is possible to enter a value of 3 in the fifth position. Whilst this is possible other test equipment will not be able to accept this and in this case the character A will be displayed.

For scheme 2 (later)
E = 1
F = 2
G = 3
H = 4
J = 5
K = 6
L = 7
M = 8 or 0

Anything greater than 8 is not a valid value.
Again it is possible to have a value, this time of 0, which other test equipment will not able to accept. In this case the character M will be displayed.
