B16A in CRX '88 running slow any ideas?

[Riviera]

if i get the vtec controller profesionally tuned, will it be better than the stock ecu guys?

no remove, sell


or get the motor rebuilt with forged internals, stage 3 cams, I/H/E ITB's perhaps???
then use your VTEC controller

[delsol9000rpms]

even then you dnt need it because an aftermarket computer should control it LOL

ok cool u guys have convinced me!

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?

cheers.

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

Just wondering if anyone knows the answer to this:

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

What dose the Block serial number start with?

Cable clutch?

Build dates stamped on the head anyway

I have the SiR ll out of an 93 EG6 170hp/125kw and she feels very punchy

Hydro clutch
Block Serial start with 5xxxx
Transmission: S4C

Ready this http://hybrid.honda-perf.org/tech/b16a/

And for gods sack loose the VTec controller!!! Honda knows exactly where the VTec crossover point should be...

ok my serial number stamped on the block is: 5016763 "B16A"...............

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