Guys,

I need some help. I am going to get the car tuned shortly, and need some direction on how to do it. I am planning on using my VAFC, and tune the cam gears. I will be using a Dyno with a wideband. Is their an order in which I should do things? When I look at the A/F mix, how do I adjust with the VAFC?

Any help/direction, greatly appreciated.

Cheers,

YV

Well, once you can get printouts of your A/F ratio after you run the car on the dyno, you can tune the vafc to adjust the fuel curve to the best way that makes power on YOUR motor.

To tune the vafc correctly, you would look at the A/F printout to find the high/low points from stoich. Then adjust the vafc +/- to level it all out.

After that, you run it again and see how you did, then readjust until it is perfect.

The actual button pushing process is laid out in your vafc manual, or from apexi's website.

 

Oh... and you'll have to tune the gears and the A/F at the same time because as you adjust one thing (valve timing, ign. timing, fuel, vtec point) another will need to be changed. Make sure you can get in 5-10 pulls at the dyno.

 

Honestly man the best tuning advice I can give is to take it to someone who knows what theyre doing. Not only someone who can work your device, but someone with experience tuning your specific setups/car.

Tuning is no joke, and has everything to do with experience. Ive seen good tuners do the impossible, and its solely based on their knowledge of how things happen and experience in making setups work. I would have a professional tune your car.

 

Thanks guys......


thats what I needed to hear.
