Thread: Tuning hints for a TD5

Interesting, mine also has * for the last digit; its a stock standard ECU.

What would be interesting is knowing what these last digits signify; if A is for improved injection (pre-mist); then I am left wondering what C, O and * (etc) mean?

any ideas ?

SETTINGS FUNCTIONS
The TD5 ecu has the READ SETTING and CLEAR SETTING to read and clear the setting.
The settings available on that ecu are the injectors codes and the accelerator type, 2or 3 track.
The injector codes are composed of 5 characters, 4 literal and 1 that can be numeric or literal. The first 4
characters are coupled two by two and the last one is single (for example NN FG 5 ).
The last character can be different because there are 3 types of injectors built from year 1999 up to now.
Type 1 Type2 Type3
C - M - 0
A - E - 1
B - F - 2
C - G - 3
* - H - 4
* - J - 5
* - K - 6
* - L - 7
* - M - 8
The Nanocom shows all the 3 possibilities for the last character, but when you modify the code you have to
write the code as it is printed on the injector; the Nanocom will automatically check the 5° code.

So do I read this to say that you first need to know what type of injector you have before setting to 'A'? Or is it just the very last character present? I also assume that this doc has the three columns shown opposite to what the Nanocom interface would display - the number is always first...

These are my injector codes when my TRS ecu was installed.

Obviously nothing for me here

Could someone clarify.
Codes show in Nanocom as- typically- LH NE O-M-C

Yet here you are talking of- typically- NB NG A

Are the first two letters in the third box just ignored and left as they are?
Tony

Clarification time....

All my injector codes are OMA in the last box.

Eg...NB NG O-M-A


Looks like we are entering dangerous territory

I'm out

since the defender td5 is "detuned" from a disco td5, is it posibul with a standed ecu to tune it so it runs on a disco fuel/map tune or what ever they changed from the to??

Hi Stig
Yes,BUT you need the ECU changed to suit the Defender.
Mine is a Defender tune TRS item.
I bought it because the flash tune ECUs for manual TD5s are hard to get,mine was the 1999 non flashtune type,I now have that as a spare ECU.
I fitted it it ran Ok,but there were issues.
Full Boost very quickly(Defender has no turbo modulator)
No Temp gauge
No Cruise control
No Aircon(these 3 were SLABS issues)
I had the ECU re-set by the supplier in Perth to enable the SLABS and Turbo Modulator.Ive lost that instant turbo blast but everything else is much better.
Will be looking into a Discovery tune,it still lacks a little where I need it most,towing a heavy trailer.City driving,AWSOME IMPROVEMENT!!!

OK all very confusing.

May I suggest that postings indicate if they are referencing a Disco or a Def. (LandyAndy know yours & some others do).

I’ve got a TD5 Defender (2001 build) it’s had the Auto Logic chip upgrade.

So the steps I need to do are;

• Make sure I save my ECU setting/file to file (backup) so that it can be reloaded/restored if necessary
• write the injector codes down. Note the first injector being the front injector which is (1) in the Nanacom
• Check the Nanacom to see what codes the ECU is holding.

If the ECU codes don’t match the codes on the injectors then

• Input the correct injector codes into the Nanacom and then save to the ECU.

And or

• If the injector codes on the ECU as displayed on the Nanacom do match the characters on the injectors “BUT” doesn’t have “A” as the last character then substitute “A” for the last character and save to the ECU.

If I understand the “CHIP upgrades” correctly they work on the principal that the injector codes held on the ECU are “correct”? So they don’t interrogate the ECU and substitute “A” for the last character?

So substituting “A” for a Defender with or without a chip upgrade may/should give some benefits. The “A” substitution is not a Disco only modification.

Is this a fair summary of the situation ??

There is a significant lack of input on this thread from anyone I would regard as been particually knowledgeable with regard to TD5's let alone fuel maps. (Not meaning to be rude)

I would personally be avoiding changing any codes atall, beyond ensuring they match the injector, that could alter the fuel map without the advice of someone who knows exactly what they are doing.

Tombie, Bell Autos etc.

Tend to agree - haven't touched mine, I have the BAS upgrade map and would like some input from Pete - I'm sure that the fuel map is independent to codes but...
A quick Google on Sat night returned a lot of write-ups that contradict this theory – many stating that the last box is a calibration measure and the different types of injectors using a different set of codes. (but how good is their info??)

There are a huge number of possible combinations of injector types and ECU models and at this stage I find it hard to believe that there is a one fit all magic code…
