cp3 info

Bump.  Anyone got anything new and juicy?

Does any one have a source on the injectors?
I have a CP3 and was planning on doing this for a while...just have been to busy. I was looking for an adequately fast controller for it.

There is an open source ECU available that is better then the MS -> http://www.vems.hu/ quite a bit cheaper as well.
A bit of a discussion on this topic on the site: http://www.vems.hu/wiki/index.php?page=CommonRail

If any one has a lead on the 100V driver board that would be great. Also you need to know the timing on the injectors. I read earlier that some had 4 wires one set reporting timing on the injector, does any one have a part number for this injector? Are the injectors Pizo? or Solenoid?

I have a micro controller to create the whole system but I need more information on injectors, and he driver board.

I also know of a few cam timing sensors, Cherry builds one.

Keep the great info coming!

Thanks for the reply Helliouse-

A page or two or three back, someone posted e-bay UK link to Peugeot HDi fuel rail and injectors.  The link is no good anymore but I'd probably start there- the 4-cylinder ones looked (from the pics) to be similar spacing to the VW injector locations.  I think the injectors would require a machined adapter ring to fit the injectors in to, then fit them in the head and work with the VW hold-downs.  As far as I know, the early HDi injectors were Solenoid.

The 100v driver board I need to do some more research on.  :/

Good article.

I believe there is a relatively easy way to implement CR into a former VE TDI.  Before my collaborative project settled on using a native 16V CR TDI as a base, we put a lot of thought into how we would put CR in a VE TDI.  Since we wanted to build an engine for insane performance, we opted on a Duramax CP3 pump (this concept carries over for our new engine since the original pump will not give us the sufficient quantity we need for our 450 HP target.  For injectors and nozzles, VAG has a 5-cylinder CR TDI with 2V/head for the Crafter with the same valve layout and injector slant angle as the VE.  This uses DSLA nozzles and piezo injectors, which can be swapped for solenoid injector bodies from the VW (e.g. VW LT2.8 engine code BCQ) or other OEM parts bin if you can't or don't want to use piezo.  You can use a number of Bosch EDC16 ECUs, possibly hybridized across a number of different applications, or you can get one of these.  This standalone ECU can drive both solenoid and piezo injectors with multiple injections per cycle.  The rail can come from almost any 4-cylinder application like the VW CBEA 16V CR TDI but you may need to fabricate the high-pressure connector lines from the rail to the individual injectors.

Great information, thanks for that.  So a VAG CR 2V head does exist.    Good to know.

I've read that entire technical manual of the Skynam, and it looks absolutely amazing.  What I wish I could see is screenshots of the tuning software, and if it has the ability to analyze datalogs and adjust tune accordingly- sorta like TunerStudio for MS.  I'm also afraid to even ask how much it costs.  But it really looks like a nice piece.

I'm still on the fence about keeping the ALH TDI for the Scirocco, or selling the ALH and finding a CBEA.  Depends on budget I suppose, though my budget situation may be changing soon, for the better. 

Even though I've read all there is to read about the Skynam, I'd still like to know more about it.

Thanks much TDIMeister-

If you want to get a 8V CR TDI with 2-stage turbo project going, let me know.  I even have the cam for it.

[Helliouse]

I already have the Duramax CP pump. So yes I am on my way to doing it.

I am just wondering if I can fit a 2.0 CR 16v head on my ALH...I hope so! But haven't found anything to say I can.

[TDIMeister]

Why don't you just get a 16V long-block?  There have been many improvements on the bottom end with the newest TDIs like a larger big-end journal diameter for more strength that started with some of the 1.9 PDs.  You will have to bore out your ALH to take the 16V CR pistons anyway; they are not interchangeable.  Then you'll need custom rods to match the required small-end taper with the smaller big-end journals of the ALH crank.  In the end, you'll probably spend the same amount of $$$ to make an ALH work than to start out with a complete 16V CR long block.  What are your power goals?  I ask because I don't believe the ALH will sustain too much loading...

[lord_verminaard]

Dammit, you are making me not want to mess with the ALH now and go straight to the 16v CR.   

*searching junkyards now*

LOL!

[Helliouse]

I am looking for 400 ftlb or higher.
I would love to do that, but I already have a lightweight crank, and girdle for my ALH. I know they are not near as strong as some of the Newer PD engines...

So the 16v head would fit on? Valve clearances to cylinder walls would be fine, or is that the reason to bore it out?
The pistons bowl is shaped that different? or is it located in a different location? If not why the swap?

I am not opposed to getting a 16v. Just can't right now...But I will probably get one as well.

The above was done on a VE TDI with PD bottom end, bored out to 1968cc with 81mm pistons.  You don't need 16V nor common rail to get numbers like that.  TDIClub might have the answer as to whether a 16V TDI head with fit on an ALH head though, if you're hell bent on it.  I still think it would be a waste.  The reason why boring out and swapping pistons is a must is that the piston bowl in a 16V is centred on the piston while on the 8V it is not.

[Helliouse]

Good to know on the centering.
I will still build my 1.9 ALH bottom end as I have the most expensive part bought already...
The 16v will come later

A project to retrofit a VE TDI to common rail is being seriously explored:

Vote on the poll in the second thread link if you're seriously interested in this becoming a kit.  The number of interest will help the person who's funding the development to make a decision whether or not to go ahead with this.  We have as objectives cost-effectiveness and being as plug-and-play as feasibly possible.
