Is it pointless to get a VAFC or SAFC if a motor (in my case, B16a1) is mostly stock? Which is a better application?

My car has been throwing a 'Check Engine' light code 22 (VTEC Pressure switch) for about 3 weeks now. I have been singling out all the possible problems, and none are it, except for, my guess, being my PW0 ECU crapping out.

I purchased a PR3 ECU, and it has seemed to fix my engine code problem. Only thing I dont like is the fuel cut-off and revlimiter. I have heard that a VAFC or a SAFC will get rid of both.

Now my question... which is better? Do I even need one? How hard are they to tune? Will it be O.K. on a B16a1 with intake, header, and a fuel pressure regulator? If anybody knows, or has a lot of experience with either of these Apexi products, please let me know... all help is much apperceated .

 

I do not believe a vafc allows you to change your revlimitter or fuel cut out...

If you purchase a vafc, spend some money & put your car on a dyno & have it professionally tuned.

I have seen too many people have problems when they install vafcs because they run them untuned with ghetto settings that they guessed would be ok to run on...

 

Thanks mtber... does anyone else have any experience with either one of these?

 

If you have VTEC, which you do, you want a VAFC. You can't change the rev limiter or fuel cutoff with it though, at least not that i've heard of.

 

To resolve your revlimitter issues & to lower your vtec crossover point I recommend you have your pw0 chipped out by a professional such as Kenji (email kenji211@tampabay.rr.com)
Or http://www.jdmshit.com/ecu/index.html
Or pacman from jhpusa.com
Or John from secret services might be able to do this for you also...

 

just curious what is the rev-limiter and fuel cut-off of a pwo campared to that of a pr3. no a vafc will not alter your fuel cut-off and rev-limiter to the best of my knowledge, as you should know it will adjust your v-tec engagement point . the fields v-tec controller will carry up your mph, this do not alter the fuel and the rev, (i think). the apexi is supposed to be better cause it has better tuning capabilities.
