[audis2turbo]

Hello guys,
I have a problem with my IDLE Setting.
Car is a Audi I5 20V ABY Engine and 1000cc Injector Dynamics Injektors.
Today i use the 1.1.27 Firmware.becouse i have the best results with idle. With 1.1.81,1.1.88 and 1.1.92 the idle runs Kangorou :-( and the revs at idle is to high!
When i press trottle and go down from the trottle the engines stopped.I think the IDLE have to  low (speed)
Here are alot logs.

Never firmware much easier to get good idle than 1.1.27 imo.

Did not see any logs from anything than the old firmware there, but in general kybernetics when you experience jumping you need to decrease the P value. Try 10. In this case you probably also could try to set the I value lower, like 1 or 2.
For D value you can have alot more on a car. Try 200.
You could also try to reduce the freedom of timing to +- 8° and speed of advance increase to 40.

In the new firmware its a bit more settings to do to get a good idle, but it works pretty well, and if you have wheelspeed input, you should be able to obtain idle like a normal car.

Also you need to have the flyback under control by diode or internal diode or you will get nowhere! It seems like the IAC does not move much at all, only the ign is controlling the engine. You could need to look at the interaction between the idle-screw at the throttle body and the IAC valve.
60-70kpa at idle looks like a bit on the high side for this engine, but could probably still be ok.

Last of all, tuning idle is usually a bit time consuming  :)
