When you see a long pause, wait and count the number of blinks again. If it is the same number you are only flashing one code, if you have a different number of blinks after the long pause then you have a second code. Repeat until the same number of blinks occur after each long pause.
You can find the ECU codes online with a search.
Hope this helps.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
