Allright guys Ive got an SIR-II swap, and I just got a VAFC since I'll be turbo'd in a month or so... I hooked up the VAFC tonight and everythings wired right I guess since all the all the sensors work and I can stall the car by giving it too much fuel.
Question is though, it runs like **** now and I can get it running better if I use like +15% through the rpm range, but even then the A/F gauge reads super rich and it still has a lot less power then before. It runs even worse if i try and use -% numbers.
Just wondering if anyone has had this prob before and what the solution was? The cars loud and constantly bogging just on idle. Help!!!

BUMP!

my best suggestion is if you have any dyno places nearby take your car there. But try taking off the VAFC and running it stock again and see how the car idles and runs. If it still runs persistant and the way you like, than im thinking it's the VAFC if you bought it used.

GPoodle

The VAFC was bought brand new, and it is wired correctly. I dont see why at zero fuel correction on the unit, the car runs richer then ****. I'm deff not paying a dyno after spending 220 on a vafc!

well for hondas the leaner the better.

slixxracing

True that, but the leaner you go the more money you better have to assist you in the near future.

GPoodle

Well the cars runs shitty, but better at like +20% all acrossed, than at 0%

This fuckn sucks

Unplug the VAFC totally, hook the wire that you cut back together and see if the car runs normal again. If it does... then its one of 2 things.

1. The VAFC is installed wrong
2. The VAFC is defective.

That's basicly what your down to.

aight heres an update ... Ive spent the last 2 hours ******* with this thing, and after soldering the wires and NOT changing anything, it now dies right after starting ... ******* a

sounds like its wired wrong or the vafc is defective.
im leaning towards wiring htough.
its too easy to mix up one wire and make it run weird.

WTF is the point of getting a VAFC if your not going to dyno tune the car?
VAFC= tuning equipment.

GPoodle

Of course I'm tuning it.....

I was refering to the fact that there was no way I'd pay to get it tuned when everything was set to zero correction and the car ran like ****.

Anyway got it working .... topic done...

you dont know what your doing bro, sorry but you dont need to be tinkering around in there if just a simple VAFC is giving you problems. Your going to get yourself into more motor problem. Best advice: dont touch any wiring!

GPoodle

Sorry man you shouldnt judge someone without knowing them.

I've built 2 OBD1-&gt;OBD2 harnesses, both working flawlessly, swaped 3 motors, and installed about 20 stereo setups. Also I've built different home electronics like computer fanbus' and small electronic stuff of that sort. Also, have gotton to AC/DC electronics 3 (involving calculus 2).

Sorry to brag or whatever, but yeah i was suprised and stumped that 10 wires could **** me over so bad , anyway though I should have read other posts and scraped the **** Apexi sends for connecting wires - i ended up un-doing the wiring, and soldering/heatshrinking everything and its works great now.
