Injector timing adjustment (near Worcester ?)
In an attempt to cure my intermittent 'pinking' rattle I have had excellent advice from you guys.

Fuel wise it makes no difference whether I use cheap or premium fuel with or without 2 stroke. Power and mpg are not lacking and I've changed fuel and air filter recently. The EGR is fine with nice quiet 'chukkas'. Its had four oil+filter changes in 26k km. But on long journeys I still get this annoying rattly pinking sound on moderate acceleration.

On Lorryman's advice I was at the dealer today for an injector learn and a pilot correction relearn. According to the dealer the 16 digit hex code was correctly assigned to the EMS and there was no evidence of fuel rail pressure being too high. They talked about running it through various 'cycles' on their diagnostics. They said its spot on and runs beautifully. But of course on the way home it was exactly the same !

This leaves one thing. I'm convinced the injector timing is slightly out and I want to adjust it a bit as others here have done. In July we're going to Malvern, Worces. again for two weeks on hols (long story). I'd love to get Alive or BAS to do this adjustment but York and Grimsby is too far really. But I will if I have to !

Does anyone know if there's any good LR tuning specialists within an hour of Malvern, say B'ham or Oxford for instance ?
Thanks !

Did the dealer do everything in the correct order?

Injection pump learn/re calibration
Injector Numbers
Injector Piolt learn (this must be done last)

I would not change the timing from standard - and in my opinion, although I'm sure tuners will try and dissagree - you should not (and in fact there should be no need) to have the timing adjusted.

Engine timing is critical, and Land Rover spend millions developing and mapping the optimum timing (and there is more than just one map that most people adjust). But apparently people tweaking in a workshop can make it better??? The fuel system, set up and control is critical to the running of a Puma Engine. And any tweaks to Pulse width or timing on a Torque based strategy is wrong.

More often than not, issues like this can actually be down to injectors themselves, with a fault that only shows up under a certain load/condition.

thanks Porny
Actually the dealer said they hadn't done a relearn before so the info in your post makes me suspicious. I see you're in Sutton Coldfield and looking at your tuning credentials is this something you would be interested in checking out ? I don't want 500nm though ! Laughing I just want to get a diagnosis from someone who knows this kind of stuff inside out which you obviously do . I can always phone IRB and book it in nearer to July if thats OK.

Rossy,

as mentioned on other posts I couldn't recommend enough that you pull the MAP (and MAF) sensor(s) out and give em a clean with carb cleaner. for the sake of 2 mins its a no brainer in my opinion.

Thumbs Up

If you're in a fix go here, they are an excellent independant with a great reputation! They will sort you out! I still use them on occasion and they're two hours from me! Ask to speak to Steve and explain your problem. They have sorted another couple of people out in a 'fix' last minute if you read the feedback.....

I also had exactly same heavy pinking issues . Whilst getting the turbo hose replaced after the recall I told them to upload the 2013 software . Bingo - no more pinking issues . Same silly rev probs and gear changes but much smoother . Can't wait to get to BAS though .

Caterham - thanks I'll do that. Thumbs Up

K9f - I'll give those guys a look in they sound great (and they look a bit posh !) Thumbs Up

Keith - yours is a 2.2 I think. I asked the dealer the other day and they said there were no software upgrades for a MY11 2.4 on the system so I'm guessing the 2.2 has already needed one !

Hello There Rossy,
I am currently facing the same problem with my defender. Did you manage to fix this issue? If yes, can you please share how you went about fixing it.
