If you have to add a bunch of preload just to get cracking pressure above .3 bar you are in BIG trouble.

Hey guys,

it's been a while. Had a lot to do with work and stuff, but I've reactivated my project.

The problem is/was I think for 99% the following --> see picture 444.jpg.

There was some "oil coal" building up under the heat shield under the turbine wheel. As you can see the turbine wheel was grinded by the shield.

Brought the turbocharger to the guys from TTE. they are about 10km away from the place I live.

Now I've got the TTE300 installed in the car. First run was yesterday. Unfortunately one of the coils died and it had misfires under high load.

I posted this, because maybe some of the new useres have some similar issues.

OK!

Did my first Log yesterday. Hardware should be OK now. Had the engine out in winter and did a lot of stuff to it. Now everything should be finde hardware-wise.

Finally I can start tuning... Cheesy

So, after the first log it seems that I have to work on the PID-Controller. The I-Value seems too high, so the boost is overshooting even out of the sensors range...

After having a look at the FR I understand it that way:

lditv_w is in between the ranges of ldimn and ldimx.
ldimx is determined by KFLDIMX.
ldimn = ldimx - value out of LDDIMXN

so I would reduce the values of KFLDIMX, is this correct?
