i forgot i started this thread,... :hmmmm:
here's a scenario,...
my vtec engage 5.2k
when tuned with vafc,... the tuner put it at 4.8k,...
as i was informed,... honda made the vtec crossover for a reason,... that is : at that point, or maybe a bit lower than that (engineers always tend to have a safety range) ur engine produces top power,...
lets say two cars : same car model with same engine,... after a few years,... with wear and tear,... the engine will not be exactly the same,...
so, tuning wise,... u might tune one car to have vtec engage at 4.8k,... the other might be suitable to hv vtec open at stock 5.2k,... it all depends on that particular engine,...
as bro shiro stated,... if ur stock vtec crossover point is at 5.6,... u might have it set to abt 5.2-5.4,... coz 4.8 i think is way too low,... unless ur engine is in stage four modification,...
my engine only stage 0.5 (shiro,... winked) hahhaaaaaaaaa!!!
