Same here ppl, i have a 2001 b-93p lude and it smokes when vtec engages... it is especially bad when the engine is cold and at slow speeds...

One time, I threw a flame outta my exhaust when I hit VTEC. I was racing a friend of mine in his GSR and he said my car threw a flame out the exhaust....Each time we raced after that, he said it never did it again. Of course all he was seeing the whole time was the back of my car.....

yeah preludes actually run "too" rich... that is why a simple vafc tuned properly gives such good gains... rich means you bog.. but dont lean too much or youll detonate..

You shouldn't be hitting VTEC when your engine is cold anyway... I didn't think that the Prelude ECU would let you anyway.... hmmm...

My bad about the wrong color code... its b-95p... IHPrelude94, it doesnt hit VTEC but you can tell where it would... there is a change in engine sound, but not power rite when VTEC would kick in... but, regardless it smokes... thanks for the info though...
