B16A

JDM Integra
ED9 is it? = JDM CRX SiR
EF9 = Civic SiR
JDM EK4 = Civic VTi-R

whats actually happening??? is vtec engaging? theyre a pretty quick motor
and being in a CRX you shouldnt be getting left too far behind if anything at all...

i suggest either removing the vtec controller as theyre basically pointless unless
your hardcore worked and/or see the track at least once a month...

Get I/H/E done all so perhaps??

check compressions
check plugs
check leads
check timing
use only PREMIUM fuel i.e V-Power, Caltex Vortex, BP Ultimate...

BTW thanks for all the help so far guys. Riviera to answer your questions - yes vtec is engaging, at 5500 according to apexi.

Ok so by basically everyones input - apexi vtec controller is useless. Why do people get them then? is it only for really worked engines? Also how does the vtec controller hinder performance.....?

Also, once i get it running off stock ecu, do plugs leads timing all small things etc, can i get it tuned somewhere locally to get it runnin optimally? will it make a difference?

ill check build date, numbers etc tomorrow and let you all know.

I appreciate all the help so far guys thanks heaps keep the input coming!

No tuning is needed or possible once your running the stock ECU with all the other useless crap removed.

Just reset the ECU by removing the ECU fuse in the fuse box under the hood for about 5 seconds.. replace and off you go

Thanks Luke.

Just wondering if anyone knows the answer to this:

ok cool u guys have convinced me to take out my vtec controller!

I had a look and its spliced into the wires running to the ecu. If i simply snip them from the stock wiring, will i be able to start my car??

I also have an immoboliser, its a pain in the ass to start.

Immoboliser has to be pressed with special prong tool twice, then turn on ignition, wait for apexi to load, then start the car.

will i experience problems if i take apexi out?

and also how much are apexi's worth these days?

does it just say apexi vtec controller?

Or does it say apexi vafc???

[skiiboy90]

does it just say apexi vtec controller?

Or does it say apexi vafc???

It says: "VAFCII Vtec Control Airflow Converter"

Blue LCD Screen with control know on the Right Hand Side.....

Leave it in untill you replace it with a standalone ecu,
Go & see someone who knows how to tune it.

u should have said vafc in the first post,big difference to just saying vtec controller.

in that case leave it in & get it tuned,but consider taking it out if your not gonna get it tuned.
