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.

u can

just have to cut the wires going to the vafc,but u have to join the vtec & map sensor wire back together for the stock ecu.

at least with it out of the car u will be able to get the car running mechanically right,then put it back in & tune it,or sell it & get that standalone it seems u r after.

with the standalone, will i see big power improvements? I have headers, catback, and pod. Nothing major, but yeah. I should get away with just using the stock ecu yeah? im not gonna do internals or anything like that....

i figure stock ecu is a good idea as honda woulda spent big $$$ making the best point to make power for the vtec to kick in yeah?

You'll see improvements once your vafc tuned correctly but not huge gains and thats a big difference to a VTec controller by the way lol

Anyway ether remove completely and get your car running right as CRXer has stated or go to someone who knows what there doing as Adrian (TODA) has stated.

I'd say if your able to, remove the crap and put everything back to stock and see if that fixing everything..

If fixed leave it till you can afford a good tune and have the vafc re-installed by them at that point..

u will never see "big" improvements to a honda series motor with just bolt on gear & a bit of tuning. There is slight improvements to be had,depending on the quality of gear bolted to the motor & the quality of the tuner tuning the standalone.u really have to do some internal work to see big improvements.

u really also only need a standalone when doing internal work or boosting the motor.

if cash is an issue,considering u already have the vafc,just make sure your motor is running properly on the stock ecu,then reintroduce the vafc & get it tuned properly by a reputable honda tuner,like TODA above.

EDIT: shut up luke,stop copying what i say then posting it before me lol.

to the OP.

stop thinking a stock crx with b16a is going to give you ballistic performance.

its a 1.6 4cyl. get a reality check please.

sure its a nice point and squirt car. I know cos i have a crx with b16a.

but please don't think its gonna give you drag car performance.

To me it sounds like your engine is fine..... (the vibe i'm getting from reading this thread)

It also sounds like you're expecting too much out of your car.

solution - save up and buy a faster car.

**skiiboy90** · 24-04-2009 06:13 AM

thanks for all the help guys, like i said im new to the honda world.

I just say i get the feeling the b16a isnt running 100% because im not keepin up with my mate in his stock dc2 integra. should i be beating him or at least close?!

im aware its not going to be a rocketsled but by the same token i want it to be running as good as possible.....

Yes, all that need to be done is to initialize the unit.
Then it will have no effect.

No need to cut any wires...

yeh but adrian,how can u eliminate that a faulty unit could be passing thru a dud MAP signal?

not saying ive ever heard or seen this happen,but id be at least rejoining the MAP wire & getting the car running properly,then reintroduce any extras.
