Recently I had the software update mentioned in:
http://www.defender2.net/forum/topic1834.html?highlight=software This resulted in me having a new ECU because Land Rover could not successfully write the new software to my original ECU without it causing engine problems. Anyway, after about a 3 > 4 weeks of running with the new software I am discovering that (mainly when cold) the engine seems to have some hesitation around 1500>2000 rpm's mainly in the higher hears (extra load). I know most software maps have a different fuel to air ratio dependent on engine temperature so I am wondering whether it is the new map or the following fault codes: ( I have put my thoughts next to the ones I think I can explain) P0100 = Mass or Volume Air Flow "A" Circuit (Blanked EGR, worked fine before software update) U0155 = Lost Communication with Instrument Panel Cluster (IPC) Control Module (don’t know, is this the problem?) P268C - Cylinder 1 Injector Data Incompatible (don’t know, is this the problem?) P268D - Cylinder 2 Injector Data Incompatible (don’t know, is this the problem?) P268E - Cylinder 3 Injector Data Incompatible (don’t know, is this the problem?) P268F - Cylinder 4 Injector Data Incompatible (don’t know, is this the problem?) P167B - Fuel Injector Learning Not Done (don’t know, is this the problem?) P0404 - Exhaust Gas Recirculation "A" Control Circuit Range/Performance (Blanked EGR, worked fine before software update) P0606 - Control Module Processor (don’t know, is this the problem?) P1103 - Mass Air Flow Sensor in Range But Higher Than Expected (Blanked EGR, worked fine before software update) I have read somewhere that you have to teach injectors as a separate practice to installing new software, does anybody know how to do this? I just wanted to know if anyone can help me before heading off to Land Rover again? Thanks  |

In my opinion the scenario could be:
P0100 = Mass or Volume Air Flow "A" Circuit (Blanked EGR, worked fine before software update) Blanked EGR for sure!!! U0155 = Lost Communication with Instrument Panel Cluster (IPC) Control Module (don’t know, is this the problem?) Due to low battery during engine starting and/or OBD scanner usage P268C - Cylinder 1 Injector Data Incompatible (don’t know, is this the problem?) P268D - Cylinder 2 Injector Data Incompatible (don’t know, is this the problem?) P268E - Cylinder 3 Injector Data Incompatible (don’t know, is this the problem?) P268F - Cylinder 4 Injector Data Incompatible (don’t know, is this the problem?) P167B - Fuel Injector Learning Not Done (don’t know, is this the problem?) the dealer miss or do wrong injectors learn and calibration procedure P0404 - Exhaust Gas Recirculation "A" Control Circuit Range/Performance (Blanked EGR, worked fine before software update) Blanked EGR for sure!!! remember new SW could mean new controls parameters P0606 - Control Module Processor (don’t know, is this the problem?) may be related to U0155 P1103 - Mass Air Flow Sensor in Range But Higher Than Expected (Blanked EGR, worked fine before software update) Blanked EGR for sure!!! remember new SW could mean new controls parameters Discovery 5 td6 HSE Stornoway Gray Outback Engineering Limited Edition

Ok guys, I have cleared the faults re-installed the map and I am still getting the following:
P268C - Cylinder 1 Injector Data Incompatible P268D - Cylinder 2 Injector Data Incompatible P268E - Cylinder 3 Injector Data Incompatible P268F - Cylinder 4 Injector Data Incompatible P167B - Fuel Injector Learning Not Done I may struggle to get the dealer to do anything as there is no MIL light on? Pete at BAS any clues mate? |

Hi
Yup , tell the dealer to Go into service functions and do injector replacement using the injector codes on the top of the injectors - entering the numbers into the IDS screen. These functions are part of a process that should be done automotically when fitting a new ecu to your Defender. The old data is read from the original engine ecu as part of the process before the new ecu is fitted. But if your old ecu did not have the required data inside for IDS to retrive, then this part of the process will still be outstanging - hence the fault codes. |

Re the mil light and your dealer not re looking at your car unless its on, you could allways remove a connector from one of the injectors and turn the key on

Cheers Pete, is this something you could sort out if I brought it to you for a service in the next couple of weeks? |

The only concern id have is your warranty and me programming a new ecu that has just being replaced under warranty not knowing the full storey as to why they havent already compleated this procedure as part of fitting it.
But if you wish for me to try , im game 
It may be De-Ja-Vo but have i not already tried on your car with your old ecu and i suspected a possibile wireing fault ? Ive something simlar going round in my mind and cant put my tounge on it. Pete Last edited by bell-auto-services on 4th Mar 2010 11:20pm. Edited 1 time in total |

I'm just thinking of a contingency plan as I am out of warranty in about 4 weeks, I'll probably go to the dealer with what you've mentioned and get them to sort it out. I'll still be giving you a call for the service though so I can pop up and have brew with you (you can put it on the bill) |

Give your dealer a call and say,,,, you was in Ripon and the car was having problems so you went to Ripon landrover and asked them to take a look.
They told you it needed the injector codes relearning after interegation with there IDS, you promplty said you dont have time now you will speak with your local dealers to do it 
Failing that ill do my best for you when in for the service,, bring the chockie bikkies

Hi !
I'm a newbie on these aspects of "tunning" and stuff....
Hope ou don't mind I use this thread to clarify some doubts I have ...
But I've been reading carefully you posts on ECU remap and I have one or two questions .... 
By doing that aren't we gonna raise some problems regarding warranty issues? If I have a problem in the meantime can't they refuse to fix something beacause I did some changes to the ECU? What do "we" gain on doing such modifications to the ECU? I mean, why more horsepower and torque? For offroad use ? Can the dealer be the one to do this sort of thing if we ask too? And by the way, the puma brings the speed limited to 140 kmh? Thanks!

Hi lrmaniac
referring to your cars and warranty,the BAS interface lets you return your car to standard tune at any point in time you wish therefore it could be made standard before any dealer visits. The gains are tipicly 28bhp and 65nm of torque. The speed limiter is also removed as part of the tuning if you so wish. Pete |
