==> if you're looking at something that controls the airflow and VTEC engagement, u can consider APEXi AFC-Neo or VAFC-II.letdoit wrote:Hi,

adjusting air input will con ur ecu into richening your car. vafc n neo will do that. If you want injector control .. you will have to go for slightly more advanced ecu pigs like emanage.letdoit wrote:anyone advise what is afc neo for?
beside can control Vtec, can it control fuel as is under fuel managment .
but reading the spec, every setting is about air and not fuel setting. can this also adjust how much fuel without adjust the air?

Hi,
wat abt the difference btw unichip-q (or any other versions..) and apexi afc neo?
Do they perform the same task.. as in getting one of them will do or they have different functions?

Pls elighten..
Im using a piggyback vtec controller just like the spoons vtec controller.It controls the vtec and nothing else.
To get the best engagement. U need to dyno it. Set it to engage at 7k rpm and look at the chart. the point where it dips it where the vtec needs to be engaged. U need to locate the highest rpm at which the hp dies on the non-VTEC lobe...then set it at that rpm then - 200rpm.Mine peaks at 5300k and i set at 5100k
Before anyone starts to recommend the Best VTEC Switchover Point for ur engine read this.
http://www.team-integra.net/sections/ar ... ticleID=59
Section IV.
But its still not optimize until u set the wide open throttle fuel map. So thats where the vafc,unichip and the others come in handy.
Im just happy i see the vtec light on
