How is it not made for the 7th gen civc? and how does the first one not have a map or equivalent? My ver1 VAFC has two maps for not only my car but any car it is compatible with. It shouldnt need diodes either all it does is change the signals up or down in voltage to fool the ecu, its not changing flow direction...? I just need more info than, "it doesnt work, it trips the CEL"...

Peace

it uses different voltages thats the purpose of the diodes and resistors... to reduce the voltage/signal being sent/received which is throwing the check engine light

So it just doesnt have a sensor setting for the EM2? Even though I'm sure Honda's not going to change what they've been using...? And thats the purpose of the unit anyhow, to reduce or increase the voltage signals to and from the ECU...?
I know my ECU doesnt like it when I change my fuel more than +/-10% and sometimes it gives me a CEL but really who needs to adjust it more than that? Turbo? If you do you should move to a standalone or AEM EMS or similar right?

Peace

What about safcII Did anybady know it will work on D17 or not

gearbox · 01-03-2005

safcII is the same unit without vtec function, so it should work just fine. I think even the original safc would work, since the problem had to do with vtec engagement and not a/f changes.

Btw, xproductionz adjusted his fuel ALOT with the vafcII after swapping an ex head on the lx to compensate for vtec.

^^^.... what he said

hey its me again, i need to know what a/f settins to use cuz my cars doin a little stutter every time i shift in the warm idle circuit...help please??

gearbox · 01-17-2005

You need to get it dyno tuned, but I doubt that's why it's stuttering (unless you have turbo or something). Goto Garage Kwai in arlington heights.

u dont have any settings that i can use for right now?..i dont want performace, i just want that thing gone, i know why its doin the stutter, maybe im usin the wrong term, but the a/f mixture is too lean, which way do i go to make it not so lean?

if you know for a fact you are running lean then look at your rpms and at your a/f guage at the same time or try to.. look at your a.f guage then as soon as it goes lean look at the rpm guage to see where along the pwerband you are running lean.... then adjust anything from that point on and add fuel...but if your running a stock head there should be no reason why it does that... but if you did a head swap thats a different story

alright thanks

Im going to install my safc soon, i think there is a orange, pink and purple wire left?

Is this correct?

the only wire that shouldnt be connected is the VTC CAM SIGNAL wire... everything else shold be connected

^^ even if i dont have vtech?
