Besides the V-tech feature what is the difference between the V-AFC II and the S-AFC II.

Specs on Apexi are quite diffrent

VeilSide AP1

They pretty much do the same thing just different in some aspects they are both used for fine tuning of Air/Fuel ratios

The VAFC Modifies manifold pressure signal and alters VTEC engagement points on Honda VTEC engines for example: stock VTEC on an AP! kicks in at 6000rpm's well you can adjust itto 5000rpm or 7000rpm its your call they are really good on N/A cars, I know because i had it on my EG aka 93 Civic hatcback with a fully built bottom end Ls-VTEC set-up. But you gotta know how to use it if not its as useless as a can of food without a can opener

The SAFC also Modifies and monitors air-flow meter signal (pressure signal in some vehicles) to optimize fuel-air ratio Vacuum.SAFC go well with Boosted cars thow some people rather go with other brands such as Greddy,HKS that can also alter air flow and what not. i actually sold one of these this week

Unless you like the way these things look in your interior, they are a complete waste of money. If you want to tune your car, get an EMS. I've never seen any noticable benefit to changing the VTEC crossover on an N/A F20C.

Pretty much agreed...

You MIGHT have some luck w/ a greddy.. but by FAR.. the EMS is the optimal solution....

Yeah - just need to find a EMS at the right price. Agree - a lot more functionality even though at this point not thinking about FI.

can anyone recommend a good shop to take the car to and have it programed with the VFAC-II, preferably one with a dino.
sorry, the post was already open and i got too lazy to do a search.
