[s-cars] Sport Quattro Engine cut off at 4000 rpm

[Frederic L'Huillier]

Joern,

The engine is cutting off at 4000 rpm even when the car is not running (=
you don't drive it).
Norbert is looking at the 2nd possibility this morning.

I think you can dream, even if he has to spent the next 96 hours without
sleeping, the car will have tons of boost for Le Mans !!!!
And to make it even worst, there will be at least another Sport Quattro as
well

Regards,
Frederic

Fred!
What is the boost pressure when it cuts,(if  it is boost related)or is it at

4000 rpms no matter what load/boost the engine has?

The most common fault is  to have the hoses to the electric wastegate
controller installed incorrestly and  the  engine  make  too much boost and
cuts due  to a preprogrammed value in the ECU.

If it  is not related to boost-conditions check the input signal from the
crank-trigger(counting rev/min @flywheel tooths) to the ECU with a VAG-COM
or
a VAG1551.

( I would like to  see some very low boost on this car, so I have a chance
to
keep up with him next wek @ Le Mans.......)
