Well i just got boosted last weekend. d16z6, 14b, vafc, and supra 440's. the vafc is set at -40 -36. The idle is real boggy and shakes my car plus when i get on it, it stutters and pops at around 6200 going thorugh 1st and 2nd. but when i start in second it wont do it. I know theres only soo much a vafc can do but can anyone help me. just tryin to get my car to run decently. o ya the car doesnt fast idle no more either

 

get some sort of engine management vafc = the suck

 

thats what im saving up for right now but in the mean time would to be able to get it running decent on the vafc

 

are those injectors peak and hold or saturated?

 

try adding more fuel, when i had my vafc on my d16z6/14b i had my low cam at 1000 rpms at -21%

the rest of the low cam i had -37% across

and for high cam

<U>4000 </U>
-30
<U>4500</U>
-29
<U>5000</U>
-28
<U>5500 </U>
-28
<U>6000 </U>
-27
<U>6500 </U>
-27
<U>7000 </U>
-26

all cars are different though you can try this but i would at least get your afc tuned at a shop until you get your car properly tuned so your a/f ratios are good

 

u need to dyno tune

this may answer your problem other than tune, meaning you might need a resistor box to solve some of your problems.

 

they are peak and hold. I have inline resistors on them

or at least use a good wbo2 and try to get the afr's right on the street.
