Can anyone advise me how to increase fuelling on my 1y engine please?
I'm not expecting much it wanted to try a few tweaks for some local roads. Engine is 45k on it and burns zero oil and zero smoke.
Cheers

As no-one else is replying, and I don't have the knowledge you need for a 1Y engine, you could try this link http://www.vwdiesel.net/forum/index.php ... 391.0.html" onclick="window.open(this.href);return false;

The article is worth reading as a whole, with emphasis on engine breathing first of all.

Cheers matey

I don't know why it is so hard for the diesel boys to share info on here, personally I don't do diesel so I don't reply but there are dozens of happy 1Y boys, be good if they could do a wiki article if there isn't already one put together

has any of the 1Y possee got time to do it ?

Aye aidan...... Not exactly feeling the love

The problem with the 1y install is that most of the time its fitted with the cs/ky exhaust which is too restrictive for the 1.9.
Any aditional fuel is going to increase cylinder temperatures and if yhose temps get to high it can lead to the pre combustion chambers getting too hot cracking and falling out of the head if this happens then yout 45k engine becomes scrap.
The first thing to do with diesel tuning is to fit an exhaust gas temperature gauge so you know exactly whats going on back there.

So, using the standard manifold is ok, but a custom exhaust to help it breath better is a better starting point? Canny timing as my exhaust is looking ropier than Jordan's gooch!
I'm guessing there is no off the shelf exhaust upgrade?

MGP makes a good point here, that tinkering with diesel fuelling can lead to unintended consequences. It might not be a "lack of love", but more like not wanting to lead into more problems.

The fuel settings on an injection pump require expensive calibration equipment to set up correctly, and I have left the settings on mine (it's an AEF, so very different setup) absolutely as standard for that reason. I always get my pumps set up professionally on the very rare occasions when they need tinkering.

None that im aware of. Just had to make one for my aaz with non standard turbo £155 for materials, bought a 24" × 5" stainless box some manderel bends and straight pipe in stainless from ebay a reel of 316lsi wire in the mig job done. Just worried now that the urge to give me box a good rub aint too much for me to resist.


If it were mine i would probably go with 2 1/4" pipe

I accidentally nudged the spindle whilst fitting Brickwerks' throttle lever. Took me ages and lots of fiddling to find a spot where it's not revving it's nuts off too much nor going slow as a potato up a hill.
I could do with getting mine professionally set up. Any ideas where to get it done? Is it a set up on vehicle on rolling road job or send pump off to specialist job?

Keytouch: If your van's driveable, they would probably do the spindle in situ. Whilst you're at it, a spindle seal probably wouldn't go amiss.

I have used "City Auto diesels" in Plymouth for years. Yes I know that's not in your area, but if you do a websearch for "diesel injection specialists" in your area, that should find a similar company. They will have all the data for setting up the pump, which is all contained in the numbers stamped on the plate on the pump body. Just as well to have those numbers ready when you contact them...........it shows you're serious. Best of luck!

This is to clarify where some of the components are, and how to adjust your pump..

Below Pictured is the non turbo no altitude compensating pump


The major difference between this, and the turbo/altitude compensating pumps is the addition of the "LDA" on top as pictured below


The most common asked question is usually about turning the fuel up or down.. Adjusting the smoke screw so to speak.. This adjustment is pictured below.. If your pump has never been tampered with there will be a steel collar crimped over the threads.. Remove that collar by some manner and loosen the 10mm jamb nut.. Best method on the car is trial and error, typically a quarter turn at a time.. When you get close you may need to use eighth of a turn increments.. But this can vary pump to pump pending on wear and such..

Turning the screw clockwise increases the fuel injected over the entire rpm range.. Turning the screw counter clock wise reduces the fuel.. Keep in mind that when increasing the fuel you may need to decrease the idle, and when decreasing the fuel you may need to increase the idle. (If you overdo it you won't be able to get the revs down at idle, and the pump may "run away with itself", revving progressively faster - be cautious!)


Idle adjustment is pictured below, it's the screw closest the engine.. The screw that is further away from the engine is the max RPM adjusting screw.. Both of these adjustments are pretty self explanatory.

Great link there buddy, I left my van with my pal yesterday (diesel mechanic) and he had a mooch about. Van is much better on the hills, yeah it's not a transformation but it's better! He is going to build me a custom exhaust toom
