^^ it was a barometric pressure sensor integrated into the ecu.... so they did have a map sensor, just not one you could see lol

That makes sense.
You need a MAP of some description to modulate boost. The early 1.8Ts still ran the N75 boost control circuit I assume?
They just measured MAP in the ECU, as opposed to a remote sensor in the charge pressure pipework.

a bam engine with a throttle cable?
im beginning to think that might be an aum (?) with a s3/tt manifold!

Why would you think that? AUM was DBW too.

not a aum, agu i meant! doesnt add up why it has a throttle cable attached

That sensor on the inlet is the temp sensor not map

Map sensor goes before TB

Looks like its had a lot of corners cut and alot of TLC

where u located ?

Erm...would that be because it's in a Mk3 and running a non-OEM ECU?
I'm guessing that would explain it...it makes the wiring far more simple.

Yea emerald uses cable throttle and no maf and I think no map

And no knock control

I'm not a fan personally

The Engine is deffo the amk/bam you can see the charge pipe on left of engine

The Intercooler size looks ok but the piping looks horrific supirised it's not damaged that engine

Wouldn't go too big either as that's just bad for boost

Look on 600bhp evos at the Intercooler pipe work, it's not that big, about same as mine, stock size is what u need

Folk that go too big are making things worse bit like havin a too big Intercooler


Basically listen to what ess three said

I wonder if this installation runs a lambda sensor and Cat?

no lambda and no cat

100% definitely a BAM as its stamped on the top of the engine

[F17BAD]

mine runs no Cat either but i do run lambda sensors and all other sensors

i run on the Audi S3 ECU  but much dofferent set up to you as i have the RS2 Turbo, manifolds and a External wastegate plus fully forged internals

[hobbiniho]

yeh i went to have a look at you build thread but i think it will take me quite a while to read  i was really just interested in how it was all meant to run with half the sensors missing  but it does run and it goes well for what is a basically standard engine, i was thinking of upgrading the TIP and sorting the intercooler then getting it mapped to run properly on 95ron fuel as we dont get super unleaded here
