I have a pro tuner in mind, but what are the best/safest settings and vtec settings? Or will the tuner decide all this? I also heard I can set the vtec to cut off at maybe 9300 rpms in case of an accidental over-rev?

 

Your tuner will determine the best settings for the VAFC based on your Air/Fuel ratio and dyno numbers. He will also set your vtec engagement point for the best performance, your vtec doesnt cut off at high rpm it is a fuel cut off. This will stay at 9000 rpm, a vafc cannot change your redline.

 

the settings are the best ones for your car as determined through A/F logging and dyno tuning.......

 

vtec is gonna be around 5700rpms, you can get away with -5% from 3k-redline without leaning the car out too much and feel a noticeable difference.

 

Dyno #'s Deathsled?

 

221rwhp

 

every car is different, the best settings are the ones that make your car the most power.

 

you can tune it yourself on a dyno.you dont need a good tuner or anything.just make sure your a/f isnt over 13.5 and not less then 12.8 for the power gain.try 13.5 then 13.0 if the power is the same richer is safer.

 

so these are proven to work?? not trying to bring up an argument or anything but I could have sworn reading people state they had no gains or something??

If this is untrue im going to start looking at these again

 

i gained 9whp with my tune... and a considerable amount around red line where the AP1s power drops off due to running really rich.... my vtec is at 5700.
