I bought the FlexiTune 2 for my Subaru Justy. Its working realy good, but I have problems with ColdStart. It takes long till the engine is starting, like there is no fuel. Normaly its working after 4 or 5 times trying to start up with button pressed 4 times (sometimes 5 times). When the engine is running, the car has small problems with accaeleration and when I release the accelerator pedal the engines goes off. When the engine is warm, its working perfekt. This monday we had -5°C and the engine did not start. I tried several times, but no starting up. First of all I changed all ignition coils and the fuel filter. Now its over 0°C, so I did not know. Starting is like described above.
Did somebody has any idea what to do?
Thanks a lot!
