It does happens. Give it a try after again after you put in a new tank of fuel.
I am not sure about it... before I got the Engine check light, I have experience some rough idle....... fuel quality shouldn't be the problem in Hong Kong... so not sure if it's a problem on the wire or the plugs contact or the racechip unit.. I have been contacting racechip Germany for this problem..... but no luck... they have the poorest customer service... haven't got my problem solved.
