When performing the injectors calibration, the engine MUST BE very but very warm!!! Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

What diagnostic tool are they using to do the injector learn? There was an issue with one tool manufacturer that had to do an update to allow the process to complete on the Puma, same symptoms.

Just got a call from the mechanic. They have updated the ECU and calibrated injectors
 - but without doing the injector coding - the 16 digit stuff…as it just won´t work…
They also managed to do the pilot learning etc. and been driving it for while without any injector noise. Could I be so lucky that the coding isn´t needed for the engine to work properly - as everything else is in place. Unfortunately I have to wait until monday to pick it up - fingers crossed all weekend… regards Christian 88 Ser. 3 1980 -sold Puma 130 - 08- sold 90 200tdi 1991 - sold 88 Ser. 3 1977 200 TDI 110 CC 2003 |

Entering manually the 16 digit injectors code is a workaround to the function "injectors learning" but the purpose is the same.
The first is the manual way to "tell" to the ECU some infos(the 16 digit code is the fuelling mass flow calibration plus more infos), the second is an automatic (and better in my opinion because it is also related to the single cylinder health state/compression value) calibration. The value is deducted by rpm irregularity and the current required to open the injectors (plus other actions). FOMOCO (Ford Motor Company) ECU is one of the most advanced (more than Siemens and bosch), similar to Denso System Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Thank you - great info - as I read it the entering of the code is not needed when performing the automatic calibration. I know that they did take the car for a ride before calibrating - it worked

Is injector learning a procedure that can be done DIY? .. and if so what kit is required? 2008 Defender 110 XS SW - M57N2 / 6HP28X

I think you can buy a kit at Ebay that allows you to use a laptop to do it.
Regarding calibration of my own defender - I sure think they succeeded Just picked it up and drove 50 km - no injector noise - at least not anything like before and the engine runs smooth. I am happy and think I will forget all about the new Mercedes Sprinter 4*4

Many (but not all) of the readily available diagnostic tools will do it. For example, BBS Faultmate will, but Nanocom (as far as I know) won't. It seems to be at the moment the biggest drop-off with the Nanocom, and hopefully a feature which will be added soon. |

I've just had the injector and pump learn done on my 2010 110 with 125K on the clock. Short story as to why it was necessary......engine has always had this horrible rattle sound at times but recently started jerking when cold as soon as I lifted the right foot.
Had a chat with an independent LR bloke here in WA (Rovertech at Bentley) and they said to remove BAS Remap and they do a full Autologic scan and update. This they did but then I couldn't reinstall the remap!  .
Got onto Pete at BAS and he advised I send him the new map and he'd recalibrate my remap. What an absolutely great service. All done in very quick time by Pete and back to the workshop I went and the above "learn" done and the vehicle is really running so much quieter. Only drawback is I can now hear the Cook having a go at me....... 
Good luck with your prob, I just had to post my experience here as previously when the stealer said they'd done the learning and updates they actually did nothing. AlanH ps. The pulling power of the vehicle is great especially when towing our van. |

Hi guys,
quick question regarding injector learning: My truck went for some mods recently and they left the battery unplugged for around 3-4 days while they were working on it and when I got it back it felt a bit sluggish. I've taken it back to the original factory map and back to the BAS v2 map, but it still does not feel as nippy as before. Is it possible that the ECU 'lost' the map? or does it need injector learning?
