ok been doin some logging with VAG-COM
(or been learning
how to use it properly
)
The MAF sensor seems to be logging ok
with RAIDHP maxflow induction kit the idle air mass in is sitting around 4.5-4.7 g/s (high end of normal but there is an induction kit on it) peaking at 166 at its highest point.
the most disturbing reading is the requested boost and actual boost under load
a particularly bad example is
requested boost - 1860 mbar
actual boost - 1320 mbar
this is obviously a leaky hose somewhere although i can't find it
Run o2 adapt is sat at a constant -0.8%
idle o2 adapt is sat at -6.4% for ages and then goes up to -7.1% after a bit.
any clues on which hoses are gonna be favourite?
also what do you listen for?
is there an obvious hissing from where its leaking
i am dropping 1/2 a bar under load at the worst point in soft limp mode so must be a big hole somewhere
