I have a 2000 si with an H22A and we are having problems with the vtec crossover. It is there but it is extremely weak. We have voltage at the vtec sylenoid and we have ran it with the wide band and everything seems like it is in place. You can kind of feel it engage but its definetly weak. We ran the same ecu on my buddy's CL and vtec hits hard. Any ideas??

 

my mates prelude had quite a weak crossover, it was normal tho apparently, they dont seem to be as noticable as the b16/b18.
