SO my friend gave me this as a gift for my GSR.
I know u have to get it dyno tuned so it could work better.
Is there anyway i could throw it on right now in my car and not mess with it
just to see how my i rev and when vtec kicks?
Or do u have to mess with in when u barely put it on.
Cause i heard stories of ppl messing with the vtec engagement and messing up there car.
SO my question is can i just throw in on now just to see my revs and when my vtec kicks.
Thanks and yes sorry for the newb question

 

Yes, you can install it and leave the settings zeroed out without affecting anything.

 

Will it be easier if i buy
the plug n play harness
does anybody have a pic how it installs to the ecu Thanks

 

anybody
and what does the plug n play harness do thanks

 

ANYBODY??

 

Plug-n-play harness is just what it says it is. It allows you to install the VAFC2 without having to cut up the stock ECU wires, in case you were to get rid of the VAFC2 and sell the car.
