Sorry not wanting to start a new thread on this there will end up to many but;-
Don't know if its been mentioned before but, the Turbo vanes alter under load on this turbo.
So I reckon the Resistor would have to be variable.
Turbo vanes must alter with speed or measured pressure, surely the vanes would stay at a certain angle that related to given speed/pressure for a smooth operation.
I just spotted your post, you seem to be confusing turbo and swirl motor, they are both controlled seperately from the PCM with different functions.
The turbo has variable vanes as you have mentioned to give the best torque and bhp performance.
The swirl flaps are purely to lower emissions theoretically, but in practice are a waste of time, which is why they are removed/disabled on the likes of BMW VX etc.
The resistor is just simulating a load on the swirl motor to the PCM.
As you have discovered if the swirl motor fails or is disconnected the PCM throws an error and puts the car in safe mode, This is a combination of restricted turbo boost/rev limit and limited gears among others to enable the car to be driven whilst preventing potential damage.

Is your EGR blocked off Al?
That's brilliant MPG your getting.
The EGR and DPF are both still in use and I am undecided yet about disabling the EGR,
But in the interests of science I may try the resistor trick to see if it works.
The mpg is a few mpg more than the 300c CRD did. I get around 42/43 on a run up to the Metro,around 50 miles at up to 70+++ mph if you get my drift.
thats what I've been saying for years,you don't need it or the flaps
As you know Ray we have been trying to figure out how we could disable the swirl flaps/motor without going into safe mode.
Simons idea of a remote mounted motor was a sound one but needed a working motor that may fail due to normal use.
When the Emulator turned up on Ebay that looked like the solution but at £100 it seemed a bit steep although there was no labour involved in removing the old useless motor,and Simon did fit one to a members car with good results.
We had a few theories about the contents of the emulator being resistors but no one tried it out.
I then spotted the resistor solution on the Merc forum and reported on here,but still no one gave it a try.
Next D5UPE came up with his guage method and although it appeared to work it seemed a bit involved...so I decided to finally try the resistor method and as we now know it works for the cost of a 26 pence resistor.
So Ray at last we can do away with swirl motors as you have been trying to convince us for the last couple of years
The Following User Says Thank You to Boro al For This Useful Post:
Have you seen the components in a Swirl motor its a crazy bit of kit.
The position must be measured. But if the turbo actuator stays open then maybe the turbo is running constant. And not measured via the potentiometer.
The content of the swirl motor consists of the positioner and a position sensor,if the position sensor detects a fault ie a jam it sends a fault to the pcm by shorting the pcm signal to earth.
It is not telling the turbo what to do,that is controlled from the pcm.
If that error signal is not received by pcm then no error is reported and no safe mode....apparently!!

EGR blank off is easy enough to do,as long as you use good quality stainless steel about 2mm thick will be enough,DPf delete is down to your wallet I'm afraid

That's what I thought.
However, D5UPE reckons his car picks up better with his tugboat mod. I'm not sure why that would be.
