Hi,
My English is bad, sorry about this
The first time I used this program in version 2.1 free.
If I connect laptop to car and starting the engine, engine speed increases spontaneously. Then, fall and rise.
Restart the car's not helped.
Helped remove clamp from the battery.
Do You know what was causing this strange behavior of engine?

Thank You for any information.

My car: Fiat Punto 2, 2003, 1,2 8V

I had the same problem once in my Punto mk2b, 2006, 1.2 8v.

here too on fiat punto 2004 1.2 8v

It is a know "issue".
Someone (like me) fix it turning off the engine, someone else have to remove clamp from the battery.

I don't know why this happen, but it's not that big deal..

Is it possible that this happens after executing some actuator command?
Or it happens every time you connect to the engine (without executing actuator commands)?

I don't remember what I was doing, but it has been happened only once.

In my case i execute actuator test.
