Changed:
The gold (8°C) engine starts nicely and rews about 1100rpm wery smoothly until the lambda get's in. Then the engine rews from 1000 to 1100 rpm with 1-2 sec intervals.
The cold (8°C) engine starts nicely and rews about 1100rpm wery smoothly until the lambda get's in. Then the engine rews from 1000 to 1100 rpm with 1-2 sec intervals.

The second smaller problem is with boost. When the turbo start's to make pressure, the boost jumps 0,2..0,3 bar over the set limit and then falls quickly down to set value. Can i do something about this? Here is the [log] file. Look at time 2384.995.

* [log] file. Look at time 2384.995.

** use 2 PWM solenoid valves, one to the bottom and one to the top chamber of the wastegate. Connect the valves in parallel electronically, but antiparallel pneumatically. That gives better response, and lower overshoot if tuned right. Higher D value can be tried if it gives lower overshoot.

Now with cold engine the car runns fine but after the temperature reaches to about 60C the iddling starts to go bad.
* 12.5 msec is very long dwell, it can easily cause problems. (probably only acceptable with certain ignition coils, during cranking, eg. VBATT=9V)
