tuned derv ZS update

[peterzs]

Keep everything crossed, for you.

Well Turbo is here.....






Hopefully the manifold being made up by some-one else for his ZR shortly by AMWautosport (used to be AAautosport), will be able to be used for me as well, as he is getting it jigged so it will be reproducible.

Then it is the controller, which has been sent off to get the pcb printed, so hopefully will arrive in the next few weeks.

then oil feeds, new downpipe, and possibly some actuator fiddling and/or clocking of the turbo pending how the manifold sites everything...

then get it running on current injectors and mapping then bump it up for some serious power afterwards.

I dont plan to go this high, but on the VAG's this unit has seen close to 250bhp, so I should get 200 with it, and more importantly not destroy itself

[peterzs]

Sounds good.

I don't come on here much Pete, but nice to see you're getting moving :P

Regarding the vane control computer, I'm being held up a bit - I've ordered some pcb connectors for the connections but a week on im still waiting :S I hope they don't all come through next week as i'm quite busy with remaps :/ be just my luck!

Once they've come it's the test power up and if the circuit checks out okay i'll start adapting the firmware to fit.

Might be a few firmware updates too as development progresses but it's as easy as swapping a chip from the board.



Do let us know how you're getting on with the turbo and all!

[p_b82]

Thanks for the heads up, no ETA on the manifolds yet myself, so we are not urgent time wise yet, but I'll be running the ZS up to Matt before I head off to the states mid sept.

If nothing has happened by then I'll put every-one in touch with each other and let you all work it out while I am away lol.

By the end of this year, I *am* going to use full throttle again though!

[dakta]

of course you will

the bits I were moaning about not coming have come, I spoke too soon! So things will progress at this end as soon as is realistically possible.

Well the car has gone back to the farm in Silverstone to have a nice stay with Matt and the VW in the unit next door!

I may end up having my own custom manifold made, as the lead time for AMWmotorsport is looking to be a bit longer than I need - partly down to the other guy taking a bit longer to get his hands on his turbo and partly Ade's workload... but we will see.

Plans as it stands for the car:

MOT & service
Waxoil and clear up the surface rust on the car - It was an advisory last year
fit the new Turbo
Fit custom exhaust manifold
Build and fit custom airbox
New exhaust downpipe - if the existing one can't mate up easily
Battery to boot to give more space for the airbox
Sort the cracked bumper it picked up last year with Matt
Have ECU remapped to suit the new VNT controller - done by post with failsafe values to start with
Fit the VNT controller

This will take a few months at least I am sure, as things have not been able to fall into place for a quick turn around I was hoping for, but should be done before the end of teh year.

Then I will get some more injectors made up, and then book it in for a long dyno session to remap again to suit these new injectors - smoke being an issue for VNT's and the vane getting clogged, but more fuel = better spool so there is a balance to be had!

[p_b82]

Right so been an age since I updated this.....

So the car went for the holiday for:
MOT & service
Waxoil and clear up the surface rust on the car

It also got another respray for 'free' - Matt paid for it himself as the job done previously was so poor, and the guy went out of business, Matt wanted to get it done right for me

I got the ecu mapped to take a shed load of fuel out for current HG longevity....

But here is the new part....

The new exhaust manifold has been fitted with a gtb1765v on another car, and the controller is doing it's thing and so far no explosions.... so....

I've put in an order for the manifold, new downpipe and oil drain.. I can get my hands on my own controller in a few months too, so then it is just fitting it all together - with the moving of the battery to the boot and the new airbox.

the great news, is that my map has taken the requirement for the MAF out so, I now have a simplified process for the airbox..

then decide on remaping with the current injectors, or to just throw in the larger 200TDI's and be done with it in one go!

[ZS Phil]

Matt sounds like a good guy to deal with.

Who is it you get to do your mapping?

I saw Charles' VNT install at POL, the manifold looked awesome but he was saying that you cant get to 2 of the bolts in the middle due to the pipe routing. He reports no leaks though.

If you are worried about soot, I'd go for the SDIs to be honest. Getting the 200 tdis completely smoke free with the VNT will take some real dyno time I would have thought. That said, I really do think its possible... really pleased with the way mine are performing at the moment.

[dakta]

Excellent stuff pete.

I'll get you a controller built, I do want to revise the hardware slightly but nothing major. Charles's controller has been very comfortable to work with, functionally speaking.

I can build you a replica controller to charles, so you can have one in as little as a couple of weeks but I am making a change (simply due to availability of parts) so you might want to hang on. Up to you really.

As discussed, you can get rid of maf sensor, no need for it at all. Your egr is disabled in the soft also iirc.
