Unhappy HELP! VAFC2 installed, now car bogs down

so I just installed my VAFC2 and Im 100% positive I have all the wires soldered to the correct ones and soldered solidly.

I started teh car up after setting the inital settings( vtec type: 1 , cylinders: 6, throttle type: arrow up).

now it seems like the car is running rich as fuck. the car bogs down, isn't nearly as fast as it used to be. exhaust smells almost like pure fuel.

also the rpm readings on the VAFC are like 1000 higher than the readings on the rpm gauge.

any of you all with VAFC's have any idea or experience this before?

what do you v6 guys with the vafc have your settings at?

yeah that's the first thing i thought when I started up and it bogged. I went straight to "initialize" and initialized all settings.

I think it might have to do with the pressure signal. I think it's reading -49 Hg or something like that, ad that doesn't seem right.

yeah I got 06 06 on there, well I think I might not have initialized it right. I'll have to try that again since after I initialized it it still stayed at 6 cylinders. Hopefully I will get it figured out tommorow, or I'll haveto take it off and resolder the stock wires.

can you hear your vtec kick in? if you dont have it hook up the ecu will be adding the extra fuel for it which would cause the problem. a buddy had that prob. didnt wire wright ran it for 2mth befor he said f-it and took it to the pro's and you can tell the difference.

you guys are retards. you can't fucking tune it without starting up the car. I guess none of you even know what "tuning" is.

anyways, for those of you with hooked up VAFC's I'm pretty sure its' teh pressure sensor that's messed up. the rpms are correct now, but the pressure stays at -42 or -43 kPg's the whole time I'm driving. I'll look into it tommorw.

what should it be?

nevermind guys, I'm a retard. I soldered the pressure sensor wires to the wrong ends of the ECU wire I cut.

I'll be back in about 30 minutes to let you all know if that fixes it, which I'm sureit will.

sure enough it works fine now. I used the one on v6p.net also, but both the white and yellow wires were so incredibly short that I had to extend them with another wire which was red, so when I soldered those wires I got them switched around by accident.

what kind of gains can you expect w/ all the bolt ons except for the light weight crank pulley, (which will destroy your crank bearings by the way)

A tuned V-AFC can net you around 10-12whp across the powerband. 200whp is pushing it though with your mods. Most 6th gen AV6 w/ intake, exhaust, headers, pullies, CL-S cams, spark plugs, grounding wires, TB spacer, V-AFC tuned get around 190-195whp. Your car will be quicker for sure though.

Btw, have you install the UR pullies & TB spacer I sold you?

crank pulley doesn't really destroy it. I had mine for two years now. alot of people have no problem with it. I got 206 whp with all my stuff.

sorry bout that. BTW my h22/p28 settings are still in there so you will need to initialize the settings and check all others since init doesnt clear all the settings. Glad to hear its workin for ya.

do you happen to know what settings initialize doesn't fix? I went through all teh low cam and high cam settings and low and hi throttle settings to make sure there are no fuel adjustments.

also, I'm not completely understanding teh air correction menu's. where its' got NE01 - NE12, are those just the points I can choose to make the fuel corrections at? also there is a low and high for the air correction settings, those are just for the low and high cams right?
