S2 Avant MTM -> RS2 -> GT3071R -> CT355

That would be the setup if your going to only going to control the lower chamber only.

Aren't you going to use the upper chamber also?

What is the benefit of doing that? I have not yet looked into optimal WG setups, so please enlighten me

[Bram]

This evening we managed to get the separate WG pipe welded underneath the car with a Opel Corsa silencer

I will try to make some pics tomorrow.

Quicker spool, no wastegate creep as upper chamber gets pressurised.

You've read this but probably not had it sink in as it's in your VEMS turbosmart thread

[A80Avant]

also Bram, the settings i have sent you are for this setup. for normal setup they are slightly different,but i havent tried the normal configuration with the turbosmart solenoid,so you'll have to try,unless your tuner insists to go for aftermarket boost control

[a4kquattro]

I would also recommend actuating against the upper chamber with that valve. it seems to work nicer in my experience than the stock routing (less WG creep, etc as has been mentioned).

[A80Avant]

Marc, have you tried the turbosmart yet? seems very nice!

[Bram]

OK, very good. I will discuss this with my tuner. Thanks all for the tips

Thanks James. Welcome back!

I promised to post some pictures of my new dumptube (seperate WG pipe) setup. It's made from 1,5" SS with attached to it an Opel Corsa silencer. The end tip of the silencer seems rather close to the 3" exhaust, but it has 8mm of space which should be enough I think. I can always adjust that end tip
I have not yet given the engine WOT but will report on the screamer noise once the mapping get's done in 2 weeks time

[Bram]

And this is how currently the engine bay looks like. I still need to adjust the cam cover inside, so it slides nicely over the 034MS HO coil plug leads. Currently the cam cover does not close nicely

Also I am looking for a way to hang my catch can behind the main radiator. There is not much space......

[quattro84]

Nice job!
Who's gonna do the mapping?

[Bram]

Nice job!
Who's gonna do the mapping?

I will do it myself, and with help of a friend who has some experience in stand-alone ECUs for our cars

[MarT2]

Nice job Bram!

What are the differences between VEMS and original motronic? What's the cost of VEMS?

[A80Avant]

Look into the forum a bit more Mat, there are answers to the questions.
