Did you check all the fuses?Anything else you may have electrical related like ground wires, that kind of stuff? Stereo equipment wired wrong?

I just replaced the ELD we will see what happens. . . 24hrs no check engine light so far. Im gonna put the safc back in and see what happens. Wish me luck , really need it!

damn damn damn.. So i went back and hooked up the blue & light blue wire to the vtm and the tdc or whatever the initials are and my car still after awhile wont let me rev past 4000 rpm's, when you try to go past 4000 rpm's it sounds like the fuel's trying to cut out PLEASSSSSSSE HELP!.. I called those idiots at apex'i and he was like the vafc II doesnt work for your car, he was like when we did a test we never got it right or something someone with some knowledge help a poor brotha out...

Make sure you have VTEC setup for type-3(low rpm engagement+pressure sensing) and make sure that Lo->Hi and Hi->Lo are within 200rpm range. It's what our car's been set up for from the factory.

If you follow EVERYTHING oin the first page EXACTLY it will work. If you did all that, you need to pull the battery and reset the ecu. This will also reset the vafcII prolly. Or just pull out the FI ECU fuse for a few seconds and that will also reset the ecu and clear the engine code. Then you should be fine. Leave the engagement point stock [****]

Ok fellas. I reinstalled the safc back at 7lbs running xtra rich(untuned of corse) and everything looks to be ok so far. No cel no stalling, no fuel cuts. Im gonna push it a little when i get off work to see if everything is still working normal.

Fyi to you new comers or anyone who wants an afc or any other piggy back. Please read the directions and install everything correclty the first time. Because of this an ELD was burned out in my fuse box. Be careful and boost away!

nice going everyone... its always good to get input from everyone...good luck sodjazero with your boosted motor.. and like gearbox said if you follow everything on the first page it will work.. dont listen to apexi....it has been tried trued and tested by both me and gearbox and i am sure a few others

SODJAZERO · 03-09-2005

FVCK. Ok fellas i give it up. It was working fine yesterday, but to day its back to the same dam fuel cuts. Im going back to my mf2/stock injects/and stock fuel system. Its too much for me to deal with. I just wanna run 7lbs rich, and i was doing just fine untill I decided to go returnline and ect ect. So it was hell while it lasted ill be posting my safc for sale on the for sale section soon.

xproductionz · 03-11-2005

have you tried returning everything back to stock and then connecting the safc?

SODJAZERO · 03-11-2005

Ok, geez this is getting frustrating. I removed the return fuel line and external pump that was installed by a local tuner shop. Everything seems to be running ok so far. .. . "knock on wood". Ill let you guys no when i get off of work. I still have the type s injectors safc and mf2. I have the type s injectors tuned for the low end(idleing, cruising ect..) and im using the mf2 injector controller for the top end(WOT, under boost). Everything is running ok as of last night. So when i get off work ill take it for a spin and see if i have any issues or malfunctions come about. Im thinking that the way they hooked up the external pump was causing problems.

OK, I hooked my civic up to a OBD DIAG tonight, I got a P1259.. any clue? MY car is still doing the fuel cut off at 4000 rpm's.. Thanxs again

Also keep in mind that it hasnt been proven true yet that the ecus on 03-04 actually counter the changes.. but based on a 1 or 2 peoples experiences they say it does.. we will find out soon enough when somone puts the vafc into there car and get it dynoed and then gets it dynoed again like a year later or so. ~xproductionz

is this also true for the 01 vic?

gearbox · 03-13-2005

I have an 02 and should be retuning in a couple months. I'll post up what they find.

xproductionz · 03-13-2005

yea my tune is still the same and hasnt changed from the day i installed my vafc2 with the ex head

parditty · 03-18-2005

Im so happy my VAFC II is working now, Got some questions now though. What does COR mean? VAI? & the other v thing? I think its like voc or something? The different displays is what i'm referring too

thanxs
