cheers

 

It's flashing because you have engine knock. The settings are adjustable, but you should probably tune out / fix the knock.

 

What could cause knock bro im still new and in a country that doea not speak english
iv put a few new parts on it could a bad ecm cause it cause i have a few elec issuses

 

Hard to say in your particular case. Here in the states we have poor fuel and the stock ignition timing is too aggressive, so we get knock on the stock tune. Most likely you need to tune the car to eliminate the engine knock. You should also make sure there aren't any mechanical issues like boost leaks etc.

 

Running 95 did do a hose change but it was not running that good when i got it compression is good is running a little rich as i can smell it

 

Just in case...
