I HAVE A VAFC ON MY B16 AND I AM ABOUT TO RUN THE VFAC HACK BECAUSE I AM TURBO N THE B16 BUT WHEN I PLUG THE YELLOW AND WHITE WIRES TO THE CORRECT SPOT THAT THE DIAGRAMS SAYS TO, THE CAR IDLES FUNNY. I KNOW IT IS HOOKED UP CORRECTLLY BECAUSE WHEN I PLUG UP THE TWO WIRES I CAN THEN ADJUST THE FUEL. BUT WHEN I PUNCH IT TO THE FLOOR THE CAR INSTEAD EXCELARATING IT DECELARATES DRASTICLLY. SO ONE HELP PLEASE I CAN RUN THE HACK OR TURBO IT UNTIL I FIGURE THIS ONE OUT THANX

 

I AM TRYING TO RUN THE VFAC HACK WITH THE 450 DSM INJ. YESTERDAY I REALIZED THAT THE YELLOW AND WHITE WIRE ON THE VFAC WERE NOT HOOKED UP SO I GOT THE WIRING DIAGRAM AND HOOKED IT UP WERE IT GOES AND NOW WHEN I GO TO ACCELERATE IT BOOGES OUT AND IF I STOMP IT TO THE FLOOR IT REALLY BOOGES OUT WHAT COULD CAUSE THIS IS IT THE TPS SENSOR OR SOMETHING

 

What do your plugs look like?

And I assume your using DSm 440s?
And i also assume your running the resistors?

 

i had this problem when i hooked mine up wrong. the cacuum sensor wire was wrong. make sure you have the right install diagram for the ecu and the harness, and make sure you tapped into the right wires.

 

NOT YET MAN, I CANT GET BOOSTED BECAUSE I CANT GET THE VFAC TO ACT RIGHT FOR ME. AND NO I AM NOT RUNNING THE 450 DSM YET. I CANT GET THE DARN THING TO ACT RIGHT LET ALONE PUT IN THE 450 INJECTORS. DO YOU HAVE ANY CLUE WHAT IS MAKING IT DIE WHEN I PUNCH IT TO THE FLOOR
