Audi 2.7T Knowledge, Stock or Aftermarket ECU?
Discussion
Not sure if this should be here or in the Audi section, but asking on dedicated Audi forums didn't achieve squat, so:
I'm putting the twin turbo V6 in, essentially a kit car.
However I have very little interest in the engine tuning side really, chassis and suspension is my thing.
It's a horribly complicated beast, and I would much like to lose some of it, but that can wait I guess.
I see plenty of older turbo engines without the mass of hoses, pipes and whatever else, and they seem to run fine!
To be honest it could probably do with a good rebuild, but it's not something I can do nor afford to pay a company to do either for a while!
Anyway, I've bought an ECU for one of these, and still have the wiring loom
would it be a relatively simple job for someone to tweak the ECU to the application (de-immobiliser, gearbox sensors, exhaust stuff etc)
I'd still want to run a motorsport-type dash ideally, but could be tempted to run an Audi display instead.
Heard that the ECU needs it?
OR would I be better off sucking up the cost of a new ECU and a tuner, and go for an aftermarket ECU?
Emerald, OMEX, EMU, DTA etc etc.
Bare in mind the project is on a fairly budget (I don't get paid enough!)
There is a mid engine'd VW Caddy using this engine running an Emerald, it was Ultimate Dubs last year.
However that is all I or anyone else seems to know about it!
it's a very rare swap annoyingly, although not a huge surprise considering the size and weight of it
here's the b

d:2.8 has supercharger kits?
2.7 is biturbo as standard, with wee KO3s
I have heard a lot of good about Emerald, and yeah the K6 is up to 6 coils I think?
Engine is an ARE, it's '04ish vintage from an A6 Allroad
In what respect well:
This is the stuff of nightmares for me!
But a lot of it has been removed and boxed as per the previous (most recent) photo to clean the engine somewhat
I believe it has VVT yeah, but not exactly critical. I guess thats what the solenoid things are on the end of the heads
I must admit I'm leaning towards aftermarket ECU as you say, seems 'the right thing to do' to be honest, especially considering the car.
Also yeah stock power isn't expected to stay for long, I'd like to get around 400whp from it (2kg/hp)
have looked at MS, thought it didn't have knock sensing needed for a turbo engine?
It is relatively cheap, popular, simple?

It's not like normal car VVT (i think?), designed to assist spooling, which isnt something to complain about

Curious about DBW/cable throttle, how does it make the car less driveable?
is it not just the difference between using a bowden cable or a potentiometer and stepper motor to open the throttle?
is knock sensing just needed for tuning the car? I thought it was quite necessary to have
egr would definitely not be going back on. It will probably have a removable pair of cats for emissions
although had toyed with having them permanent with a diverter valve. not a lot of space for the exhaust mind

yeah i've seen a few forum threads where the most menial task requires taking half the car apart.
If it wasn't for their awkward Quattro system it would all be a lot easier to access
But for me i'm not likely to have any big issues with access!

Sounds like VVT won't be as complicated as i was expecting then, thats good
I see the benefits now, sort of, thanks. especially with the traction control and such i can see DbW would be necessary
Had a look at the S6, seems very nice indeed although the £1600 price tag less so
could I at least still use the stock sensors? Assuming that's not part of the initial cost.
Any idea about the tuning side? As buying the ECU is only half the battle really.
I can't help think that most of the hard work has been done already in the £120 stock ECU though
