HELPPPPP NOS checkengine

Yo guys what up?

I'm from the Netherlands and got one big problem

I've got one problem with my HONDA civic SiR(b16a), about a week ago I installed a NOS kit in my car .
The first time I tested it , it was ok!
But today when I went to a track to test it for the first time my checkengine light came on. ( I switched it on in the 2nd gear) after that I reset the ECU and tested it again without nitrous this time my check engine went on again.

The check engine light flashes 7 times.

I really need some help!!!!!!!!!!

Could be any number of things!! My first guess would be a leak somewhere in your intake tract though. Anywhere along the tract from your intake to the throttle body. The reason I say check that first is because you just installed a n2o kit, so it may not have been installed perfectly. Meaning there could be a leak where the nossles are afixxed. Then again I'm taking crap shots in the dark here...TAKE IT TO THE DEALER OR SHOP AND GET IT SCANNED!!!

Just take it to a NOS specialist
