does anyone know how to tune your cars using this ?

 

unless there is something i am missing, a vtec controller only allows you to change the vtec engage point, so no tuning is possible.

additionally, here is a web page explaining roughly why piggyback devices are not suitable for tuning. http://mycomputerninja.com/~jo....html

 

i was tweeking with it earlier and my idle started to drop...
but thanks for the sight bro

 

the best thing to do with a vtec controller on most cars is throw it in the trash. Get the ecu tuned and you will be much better off.

listen to these guys they know what there talking about.for what u spent on that **** u could have gotten a chipped ecu for half the cost and still had money to spend.vafc/safc are nuttin but over priced **** that only ricers buy.

 

yeah ...
its coo tho, i got it for free soo no regrets here =D

 

What kind is it? If its a vafc you can tune your fuel maps but wouldnt suggest doing so unless you have a wideband. There is also something dealing with these things automatically advancing timing, witch is something you def want to look into before you started [freak]in with it. Get it on a dyno and it will work fine.

 

thanks for the advive bro !!!
