LDA grind? - Nathan1305 - 25-01-2015
Just been looking at my new pump to get an idea of how they work and where things are, and I noticed the LDA pin looks a little different to standard plus it has DAN scribed on the bottom
has this been ground and if so is there a chance it's been Gov modded? [attachment=21331]

Not everyone that grinds an lda does a gov mod. Only way to know is either take pump apart or risk blowing engine by revving it really high
RE: LDA grind? - WiNgNuTz - 25-01-2015
Do you know who owned the pump before you? Just out of curiosity...

I'll look at how to take it apart and may give it a go

No I don't believe so, I've just noticed that there's someone on here called Dan who does LDA grinds so may be one of his
RE: LDA grind? - WiNgNuTz - 25-01-2015
Most likely, don't think he spends much time on here any more, but he did do a LDA grinding service for a while...he even offered to help me fit my Bosch to the DT, but I never managed to get that far with it!

Fair enough
I'm trusting myself to fit my pump but really not 100% confident in fitting it
RE: LDA grind? - WiNgNuTz - 25-01-2015
I'm not really one to say, but it shouldn't be that difficult if you've got all the bits required! My biggest stumbling block was that my pump needed rebuilding ideally before fitting, which is why it never happened. It got fiddled with (inb4giggidy) a few times, but never stripped it right down to clean and reseal.

You can tell if a pump has been gov modded as the throttle arm will feel considerably stiffer in the last 50% of its travel. Sometimes you can feel this through the pedal in the car, but if not its usually obvious when you operate the lever by hand in the engine bay.

From what I understand and have seen, the fitting is pretty straight forward, it's just getting it to start after. Some have problems as you can move the pump on it's mount to adjust the timing to get it to run right.

Yeah when I move the throttle by hand it moves around half way then becomes stiffer. Sounds like it's gov modded!

Haha Dan was the one who did the LDA grind
so at least it's done properly. And by the sound of it it's been gov modded as well so I should be good for some extra power! Just need a better turbo now
