i just got my vtec controler in and i dont knoe wut settings for my civic ex to make me have good prefoments, my mods are cai , fuel regulator , cat back exhost, and underdrive pully, so wut would be the bast setting for my vtec controler??

 

go to a dyno make a run on only the normal lobe then make a run only on the vtec lobe and where they cross theres ure optimum vtec point

 

what about my fuel do i have to do any thing to that ???

 

umm u have just a vtec controller? all that does is adjust where vtec engages

 

but would i have to addjust my regulator to compreent with my vtec for more HP???

 

every engine is different. if you dont tune that thing with a wideband O2 and a dyno you could be running super lean and cause damage... in GT3 things dont break... here you have to know whats up

 

i like that but with thoes mods dont wory stock fuel pressure will b fine

 

I am just trying to get our friend to realize the need for a 5 gas O2 sensor for proper tuning... you will get so much farther faster, safer on a dyno with the right person interpreting the data. 15-13afr is stoich or target... sometimes adding fuel helps also, I have no first hand exp with this aspect of tuning yet however, I have seen others do so in the shop. hope it turns out good.
