I was following my friend in his EK9 on the weekend and the 1st time he hit the V-tec Black smoke came out the back . Any ideas what he should check ?? He said it use a little oil but not much
 
black smoke is generally due to over fuelling.check ignition timing, fuel pressure reg maybe.is it stock?
 
sounds like its running rich .try replacing ignition components if it is really horrible. a tune up is most likely needed
 
What ecu are you running? stock?
